Abstract Located on the proposed Delhi-Mumbai industrial corridor, the city of Surat plays an important role in the production and exportation of textile and diamond in the world market. It is known as the diamond capital of India, and one of the fastest growing metropolis in the world. The rapid development of industries led to an explosive population growth of 2 million people in the past 10 years.The high demand for accommodation and further industrial development has put huge pressure to the city, causing congestion in the centre, spreading into the urban periphery, and fragmenting the rural agricultural landscape. Therefore, the design looks at creating an integrated urban network at the periphery of Surat to facilitate the projected urban growth of 1 million habitants. We explored how the forty-four existing villages and settlements can be utilised, and reorganised to form a series of inter-dependent community clusters, which together caters the multiplicity of urban growth such as migrant population, cultural diversity, meaning of transportation, and job demand.

DMIC “Delhi-Mumbai Industrial Corridor is a mega infra-structure project of USD 90 billion with the financial & technical aids from Japan, covering an overall length of 1483 kms between the political capital and the business capital of India, i.e. Delhi and Mumbai.� (DMIC, 2013)
Located near the western coast of India, Surat is the second largest metropolis in the state of Gujarat. In the past ten years, Surat has grown to become the 8th largest city in India, it is also one of the fastest growing cities in the world.
[Introduction to the Surat City, India - General Context of Surat]
Being located on the proposed Delhi-Mumbai industrial corridor, Surat is very well connected with the rest of India through two national highways. The national highway no.8 connects Surat with New Delhi to the north, and Mumbai to the South; while the national highway no.6 (also known as the golden quadrilateral) connects Surat all the way to eastern India. The construction of the two sea ports, as well as the Surat airport provided another level of transportation, and together with the highways, they made Surat a competitive location for industrial developments.

Since India started its economic reform in 1991, privatised small scale manufacturing industries were encouraged all over the country. With the advantage of transport connection through national highways and sea ports, the city of Surat replaced Mumbai to become the largest production base for textile and diamond industries in India. During the past two decade, 40,000 small industries were opened. in the city. Surat is now known as the Textile and Diamond capital of India. It produces 50% of man-made textile in India and polishes 90% of diamonds in the world.

Demand of accommodation and amenities
Although the process of industrialisation has boosted the economic growth, it has also put the traditional agricultural production pattern under threat. As a city that is surrounded by rich and fertiled soil, agriculture has been the dominant industry in Surat, and it has supported hundreds of local villages throughout the history. However, due to the rising demand of industrial workers, a large percentage of farmers have given up their agricultural job, and transferred into industrial workers for better and more stable income. While industries are craving for skilled workers, agricultural industry is losing the labour force and starting to decline. The rapid growth of industry has not only attracted local farmers, but also external migrants from nearby cities. This has led to an explosive population boost in Surat, which at the same time, dramaticly increased the demand for accommodation and amenities.

What has come with the population boost, is the increasing usage of private cars, and other vehicles like richshaws and motorbikes. It is said that the growth rate of vehicles has been over 6% per annum in Surat (JHA, A, 2013). In order to cope with the rapid urbanization and to ease the traffic pressure, a mechanism for smooth flow of traffic need to be evoloved. Therefore, urban highways and flyovers have been continuously planned and constructed during the past seven years. Today, Surat is known as the city of ‘flyovers’ by having the highest number of flyovers in India. It is planned for Surat to have 94 flyovers built by the end of 2015, and 63 of them have been built so far. The flyovers have cut down significantely the travel time for people going into the city and the surrounding diamond and textile districts (WIkI, 2013)

The images to the left show two major examples of flyover in Surat. One runs over the Majura Gate, which is located at the old city centre. It is one of the very few multilayered flyovers in India. The other one is the eastern expressway. It is one of India’s longest flyover under city municipal limits in the four lane category.

The boost of industries facilitated the development of a number of industrial units around the city, ranging from large scaled special economic zones (SEZ), to small scaled private entrepreneurs. Due to the continuous high demand for new indus2012 trial lands, and the associated accommodation needs, the agricultural area at the periphary of Surat has soon started to be urbanised. By seeing how the economical benefit of industrialization overcame the traditional agricultural industry, more and more land owners in rural area become wilful to sell their agricultural land to real estate developers for quick income, especially in the villages that are located near existing infrastructures.

[Introduction to the Surat City, India unorganised urban growth and isolated rural villages] While the villages that are located adjacent to existing infrastructure have been engaged in the rapid development, most of the rural villages, which scatters across the agricultural field and being located further away from major roads, remain relatively isolated due to the lack of infrastructure. They are left out of the development process without any benefits.

In fact, lack of infrastructure is a serious problem for the development of rural villages in India. In terms of infrastructural coverage, statistic from the India Rural Infrastructure Report (BHASIN, A 2007) shows that, infrastructure distribution in the rural area is significantly lower than the cities in quantity as well as quality.

Public transportation is also severely insufficient in Surat, which is one of the major contributors to the congestion in city centre. Comparing to London, who has a similar amount of population as Surat, 500 buses are used with 9,500 bus stops to serve 8,174,100 inhabitants, where in Surat, there are only 125 buses running in 44 routes, serving a population of 6,462,002 (ONS,2011).

In order to relieve the congestion in city centre, and to provide more accommodation to cope with the population growth, the governenment proposed an 66km long Outer Ring Road (OTR) around the city. It includes the expansion of a 37 km long existing road that currently encircles the city, which will be converted and upgraded, and the construction of a 29km long new road to close the circle. The finished Outer Ring Road will be 90m wide, which is equivalent to 22 traffic lanes. The new part of the Outer Ring Road will be running through the rural area, affecting more than 20 villages, and a large amount of agricultural land. within 500 meters on both sides of the 90-metre wide road, the land will be converted into residential zone through formation of new TP schemes. The proposed residential apartments have a hight limit of 23 stories, meaning that if the scheme is fully developed, it will be able to provide enough accommodation for nearly another 9 million people to live along the Outer Ring Road. That is 10 times more than the projected population growth by 2025 (Times of India, 2013).

[Outer Ring Road - two major deficiency of the proposal]
Although the development of the OTR will provide sufficient accommodation and improve the north - south connection at the city periphary, it is not considered to be the best way to deal with the city’s rapid urban growth. First of all, the OTR is a one dimentional approach since the whole traffice load will be concentrated on only one wide road. The picture to the left shows an exapmle of what a 22 lane road would look like. Without the support of secondary road networks, any accidents that take place on the ring road will easily lead to a traffic break down, and create severe congestion in the surround area.
23
Architecture Associations | Landscape Urbanism | 2012/13
Another deficiency is the lack of designated streets for different road users. Cars, buses, bickycles, richshaws, pedestrians, road venders and cows will all be sharing the same road, just as most of the major roads in Indian cities now.This is a major factor that is causing constant crowding and chaos on the city streets. when out ring road proposal comes true, and when the high residential
apartments are fully developed alongside the ring road, thousands of inhabitants will be living closeby to this giant infrastructure. All their needs of streets life, such as the need for smooth transportation to work, the need for safe cycling, the need for pleasant pedestrian walks at so on, will all be relying on one road as there are no other designated networks.

[Outer Ring Road - two unconsidered layers: the current industrial and agricultural strucutre]
Aside from the two major deficiencies, there are another two layers of transportation that have not been considered by the OTR proposal: the textile industries and agricultural production, which are the two major economic activities on site. This diagram indicates the two main types of industrial system - the Special Economic Zone (SEZ), and industrial parks. Both of the systems are privately owned, often located at the periphery of the city. Currently, the required raw materials are imported from outside of the city into the industrial zones indicated below for production. The final commodities are shipped to the central market once produced. Most of these industrial zones are previleged with power source and dedicated transportation routes within their gated communities, aggrevating the extreme contrast with the surrounded villages which are often suffering from poverty and insufficient public amenities. The government proposed ring road would only benefit the already previleged industrial communities, while the surrounding villeges remain to be poor and neglected.

The other major activity on site is agricultural production. It is also an independent system that runs parallel with the industries. The distinctive co-operative agricultural system though is one that unique to many of the Indian cities. Although farm lands are owned by private individuals, once crops are harvested, the crops are often sent to their designated talukas which manages the rest of the sales and distribution of the product. This systsem allows farmers who own smaller plots still get benefits from selling to the bigger market as crops are sold collectively.

In order to obtain a better understanding of the impact ring road constructions on urban formation, examples of ring road cities of various scales are chosen as case studies to analyse the issues regardding sprawling, urban fragmentation, congestion, arable land consumption, and the cost and effects of this tpe of mega infrastructure. Beijing is used as a precendent to analyse the relationship between ring road and urban sprawl, where infrastructure become increasingly difficult and expensive to build due to sparse and inefficient development. The idea of segragation is also explored. Studies of Mexico and Moscow city focus on congestion issues and the linear approach of ring road infrastructure. Since road roads are built one after another whenever the car population exceeds the capacity of the existing ring, the ring road construction is indefinate because it does not actually solves the reality of the problem. Cairo’s ring road proposal is a fail attempt to preserve arable land. Contrary to the goverment’s intend, after the ring road was built, the aceage of arable land in the city is reduced drastically. Cost of the ring road is also being examined, cause one to reconsider the twisted priority of the government’s proposal for ring road construction, while many urgent issues more closely related to the general public are pending.

One of the major problems that a ring road causes in city like Beijing and many other sprawling cities is the increasingly segregated condition between the inner and outer ring area. As the city grows it would innevitablly expand beyond the boarder of the ring, forming informal settlements such a slums or poor communities close to the fringe of the ring, while luxury, privatised gated communities develop far away from the city center and the traffic ring, making construction of infrastructure extremely difficult and expensive

[Government Proposal OTR]
On one hand, the Outer Ring Road proposal has neglected the impact to its surrounding settlements and agricultural landscape. It suggests a mere top down remedial solution for traffic and population growth. On the other hand, by connecting north and south of the city through one straigt line, the Outer Ring Road in a way is giving red carpet only to the few industrial nodes, and the few villages adjacent to it. Most of the rural villages and settlements are unbenefited from the development. Therefore, the prosoal is a one-dimensional approach, that will eventually aggravates the degree of segregation between urban and rural relationship, and creates uneven distribution on social and economical resources.

[Our Proposal]
For our proposal, by taking an infrastructural design approach, we look at how a multil-layered road network can be created to reorganise, utilise, and activate the forty-four existing villages to form a series of inter-dependent community clusters. The proposal will address not only the traffic and accommmodation demand, but also cater the multiplicity of urban growth such as migrant population, cultural diversity, meaning of transportation, and job demand. Major aims of the proposal will include: - Provide multi-dimensional road network to accommodate the traffic demand(2,104,407 cars by 2025) - Promote public transportation and cycling. - Provide accommodation and social facilities for 1million people - Provide opportunities for inter- dependent relationship between agriculture and industries.

For infrastructure, instead of providing only one highway for all modes of transporation like the ring road model, a network which caters to different modes of transportation is introduced. The core strategy of the design is a polycentric model, which is shaped by the loop system of food supply and employment within each cluster to accomplish self-sustaining model within each cluster. The two major componments of a cluster, the core and the village, perform a different role in the two types of clusters - industrial and agricultral,. For the core, for both type of the cluster, provides primary urban amenities for its villages, Specific to the industrial cluster, the core also perform as textile trading and techonology hub. And in turn, the villages, as primary agricultral production, provides raw material and labor for the industries. As in agricultral or community type clusters, the core act as a resource collection and distribution hub like the Talukas, and in turn the villages provide food supply and employment to the community.

For our proposal, the aim is to not merely paying attention to solve traffic issues, but approcah the project in terms of social, economical, political as well as environmetal aspects. Suggesting a multi-dimensional solution to the urbanization of the periphery of Surat city. This proposal aim to tackle four major issues of the site which includes infrastructure and public amenity development, as well as food and employment supply of the individual communities.
Polycentric Proposal
DESIGN STRATEGY
The condensed diagram explains our design strategies compare to the one proposed by the government. The one dimensional solution to decongest the city is to put in a 90 meter wide ring road, connecting point A to B where the current SEZ hubs are, empowering the already much privileged industry. By simply widening 500 meter on each side of the ring road for 23 stories high residential development, ignoring the affect to the surrounding villages and its existing fabric, as a solution to accomodate the expected population growth.

In order to give a structural organisation to all the scattered villages and settlements, we first studied the existing settlement pattern at the periphary of Surat, and their relationship to the essential service points. Based on the study, all existing settlements are catagorised into 4 different hierarchies: 1. The central textile and agricultural market is the largest unit. as it works as a central point for textile and agricultural goods exchange. 2. Talukas, are smaller town centres that provides social facilities to their nearby villages. 3. SEZs, a special economic zone that facilities hundrds of industrial companies. 4. Finally, all the existing villages and informal settlements are identified.

After the exsisting villages are identified, we indexed the movement of workers travelling from home to each destination point, including the central textile and agricultural market (image to the left), the talukas and industrial SEZs (middle 5 images). There are two base information used in this analysis: 1, the major existing roads that have paved surface, and 2, where existing roads are insufficient, we designed the shortest route to go through the nearest village. All the individual indexes are then put together into one combined analysis drawing (image tothe right).

From the combined indexing drawing, we first analysed how many times each existing village is passed by travellers, i.e. the frequency of being used as a transitional point for the most effecient journey.These few villages become the potential community cores. Then we either kept, or adjusted, those cores to the best location according to existing site situatikon, such as the scale of the village, and the amount of exsiting facilities they have. Image to the left shows the proposed final location for village cores. After village cores are located, a number of village cluster are then formed by addressing the rest of the villages to their closest, or most reachable cores, as shown in the image to the right.

after The proposed village cores will Agri - Industry be working as talukas (hubs), that Interdependency provides urban facilities to their nearby villages. According to the location, villages cores are classfied as either agricultural cores, or industrial cores. As the green cores are located in the agricultural area, they will provide agricultural research facilities to support the development of agriculture, and work as talukas to server goods distribution and exchange for local farmers. The increased number of talukas will enhance the existing agricultural communication, encourages the diversity of agricultural planting, and thus bring balance back to the market. The orange cores that are closer to SEZs, will be designated to provide industrial facilities such as technical reserch centres, IT hubs, resource collection and exchange centres to support the industrial development.

[Design development stage 1 - the proposed highway network]
Upon on the finalisation of village clusters, the first two hierarchies of the overall transport structure are created at the city scale.
national highways
primary roads
The most prior road hierarchy is the national highways. They are the primary network for crop transportation, so they are specifically designed for heavy vehicles. They are well connected with the existing highway system to enable the shortest time for raw materials to be transfered amoung farmers, industries, ports and other cities.
The second road hierarchy at this scale is the primary road system. They provide a straightforward network through all village cores, while trying to avoid other secondary villages. The aim is to provide the most effecient connection between each village cluster and the highway system.

[Design development stage 2 - the polycentric relationship within one cluster] The proposed 1 million population will be evenly distributed into each village clusters. For village cores, we aim at developing them up to a radius of 1.5 km, that will accommodate 13,000 inhabitants. While for each village, the development radius will be 0.9km, and accommodate 8,000 inhabitants. Taking this industrial cluster as an example, there are three villages attached to the proposed village core. The core works as the primary urban facility hub, that provides all sorts of required services to its villages, such as resource collection and distribution, goods trading points, technology hubs, etc.Villages on the other hand, accommodate residential communities, provide workers to the core and futher industrial hubs, provide agricultural production to support the demand for textile raw materials, and other food supplys.

[ Cluster Scale General Road Structure and Hierarchy] After the estimation of future population to be accomodated, the general structure of roads and its capacity are designed according to the different population density distributed between cores and villages. Bundling technique is applied when formulating the hierarchy of the roads. This technique also materializes the constructed geometry, giving weight and spatial quality to the overall fabric structure.

[Design development stage 2 - master catalogue of the proposed road system] According to the proposed road hierarhcy, the catalogue of road system is developed for the cluster scale. It includes three major catagories. For transportation between villages and cores, highway junctions will be built to enable non-stopping, smooth transportation for the transfer of goods, and buses. As the roads start to peel off from highway junctions, they spreads into the urban area in a lineal form, that enables most direct connections to other areas.

[ Chosen Plot for Development ] The core of the cluster is taken to demonstrate the strategy for laying out the base geometry for the fabric of each village. The two main objective to the method is: 1. constrain the size of the develop plots, and 2. allow aggregation ability for when new plots are to be developed and joined to the previously developed one. Because most of the villages are now laid out with agriculture plots, the plots are used in this strategy to be regenerated as a new geometry for better adaptation to fabricate city layout. The very first step is to choosing the plots for development according to the population needed to be accomodated.
63
Architecture Associations | Landscape Urbanism | 2012/13
[ Radius for Development ] In order to constrain the plot sizes, a gradual enlarging radius are inserted. Plots to closer to the center are smaller, which mainly be developed as smaller scale and residential program in order to create the least contradition with the existing village. Plots further from the center would increase in size to house mix - use and other commercial development.
64
[ Plot Point Aggregation ] In order to allow aggregation abilities, corner points within the designated radius range are taken to create the base geomtery of the fabric. So when next plot is bought up to be developed as the community expanse, the fabric could be joint with the old.

[ Design Development Stage 3 - Case Study of Singapore Road Distribution for Vehicles ]
In order to gain a better knowledge about how many roads need to be introduced to our proposed villages in Surat, we took Singapore and Copenhagen as two example cities to researched into the distribution of vehicle roads and bike lanes. For each case study, we analyse the population, density, and the general hierachy of a particular type infrastrucutre.Then we make a comparison to find out that, for each type of infrastructure, the average length, spacing, and the no. of road required to serve that particular amound of people. This exceries helped us to gain an insight about the amount of roads we should propose to suit the population density. Singapore is a country small in land but large in population. It was chosen for the study of cars because it shares very similar problems with Surat, such as traffic congestion, narrow roads due to the historical urban planning and the rapid urban growth.

Copenhagen is known as the bike city in the world. Around 52% of all daily trips in Copenhagen are made via bikes, and every day, people travel 660,000 km by metro but 1.2 milllion kilometres by bike, which almost doubled the amount.This means that more than 1/3 of the population in copenhagen commute daily by bike. Copenhagen has more than 390 km of biking lanes and bike traffice lights, these lanes range from the dedicated bicycle highways to small bicycle friend roads.The infrastructure is built on the fact that a bike is not only the cheapest and helthiest way to get around the city, but also a very important factor in reducing carbon emission (VISITCOPENHAGEN, 2013).

Image of a rural village in India
[ Design Development 4 - Study of the Traditional Indian Village Layout ] In order to design the building typology for villages, studies were carried first to gain an knowledge about the traditional Indian village layout, building typology, and meaning of public spaces. Traditionally, village means a small settlement of either one big caste group, with a couple of smaller castes, or a number of medium sized caste groups. They are generally small in size, with a population less than 1000. The layout of villages varies in a number of different forms, typical ones include shapeless clusters in a compacted nuclear form, lineal / rectangular form, dispersed form, and form of isolated homesteads (NANDI,S and TYAGI,D,S. 1969) But regardless of the forms, one thing in common is that people, especially migrants, tends to stay within their own caste groups, or the ones that is in the same social class, and share similar religion, language, or culture backgrounds.

[ Design Development 5: the Development of Highway Junction Typology ]
Based on the previously explored catalogue of highway junction design, a initial design of the vehicle cirulation was carried out with a proposed junction at the edge of a village core. As shown to the right, the junction roads are designed to enable multi-directional movement between two main roads. The section above shows how a slower traffic lane (yellow), which requires smaller turning radius, can be added in to create a terraced, and multi-layered junction complex. The section is designed to be halfleveled, providing entrances and opening on both side. This allows to create a car zone on the side of the building, while keeping the other side of the building only for pedestrians.
87
By applying the section along the highway, retail, commercial, and residential programs are generated along the roads. Carparks are created with entrance only from the same side of the road, while all areas inside the junction circle are to be used only by pedestrians. Two ovals are create in the inner side, which can be used as public open spaces, and a central plaza is created as the two circles touches, to provide pedestrian, as well as bicycle connections through different ramps. Therefore, instead of constructing the conventional type of highway junction, which would eventually take up a large amount of land, this design transforms the wasted junction spaces into a multi functional complex, that provides retail / commercial spaces, residential areas, public open places, and a large central car parks that serves not only the visitors, but its surrounding residents.

[ Transforming the highway junction into a multi-tasking hybrid mechanism... ]
In many cases of highway junctions, the space required is often large for the sufficient radius to ensure smooth flow without reducing the traveling speed. A distance up to 60 meters of from these junction constructions are usually unusable due to the poor sound mitigation or safety design. When these junctions happen within city areas, it would be a waste of land resource if many of the junction voids are left as non-functional spaces. To better utilize the junction voids in an land thirst city, we proposed a design solution to transform highway junctions into a multitasking system combining with traffic, functional complexes, and public open plazas. Depending on the different junction sizes, various programs could be inserted into the hybrid mechanism where high speed traffic and pedestrian activity co-exisit. If the junction is constructed further away from the city at industrial zones, the prototype of the junction complex could be apply, possibly with a different modulation to cater for goods loading and storage, commercial vehical parking, or any other industrial related facilities. In the case presented here demonstrate an example located in an urban area, with commercial and residental complex facing towards an open public ground on one side; and on the other, connecting with car route as well as pedestrian corridors leading into the city center.
[The Informal Pockets ] In between the busy intersecting network of different movements, with scale large and small, intimate pocket spaces emerge and spotted around the city. Because intricate circuit constrains and divert the movement of car traffic, pedestrian friendly spots like this could be generated more easily. Since social and street life is key to India’s everyday life, the informal social spaces offered people more options to interact within the communities.

[Cluster Core Masterplan ] Ultimately, our proposal has created a city with sufficient infrastructure which not only ensures smooth traffic, but also activates and empowers the surrounding villages, which would otherwise be wiped out or neglected by the government’s ring road proposal, by injecting infrastructure that caters to different user groups. Instead of relying entirely on the city central for urban amenities and public infrastructure, communities at the periphery of the city of Surat are powered by cores of each clusters. Hence, traffic going into the city from the periphery would be greatly reduced and the city center would be decongested. The over lapping circuit generated here allow the city of Surat to grow coherently. At the same time, with the layering of programs on top of the intersecting network of different scales, out proposal has allow another social dimension to emerge.

[ Outer Ring Road Model Circuit ] With the Outer Ring Road model as the Surat government proposed, the illustrated circuit of the area revealed the imbalanced activity of the site. The completetion of the ring road (the left half of the ring was part of the existing road network) only enhanced the linear connection between the north and south of the site where the industrial groups were located. Since the surounding villages, especially the ones in between the new ring road and the existing national highway, are so poorly connected, this A to B connection would further previleged the gated industrial communities with almost exclusive tranportation route, leaving the area even more segregated. The segregation aggrevates as the villages or communities located closer to the ring road would developed sooner than those who are further away from the benefits. Some would even be completely wiped out for the construction of the half ring. As the white circles indicate, the potential interaction point (where majority of the traffic and activities meet) of the site are almost all located on the ring road and the national highway. As all communities immediately adjacent to the ring road need to cross the ring into the city for services, these junctions would become overwhelmed with traffic and eventually break down at points. If one interaction point collapsed, the entire ring is hauled; and since the ring is the only formal road connecting the outter and the inner city, all the adjacent communities outside of the ring road will be seriously affected.
Interaction Point Village and Community
[ Polycentric Model Circuit ] One of the distinct contrast between the ring road circuit and the poly-centric circuit is that the latter creates a more evenly distributed fabric. As we have discuss at the beginning of the project that one of the primary issue that slows down India’s development is the lack of infrastructure. Many of villages are connected to formal road networks, and even if so, it is often poorly designed roads that lacks designated purposes catering to different user groups, causing constant chaos on the roads with all kinds of vehicles, pedestrian and animals packed on one signle road. The poly-centric model connect clusters of villages with network of different hierarchy. While assuring the sufficient fast routes for industrial tranportation, smaller scale circuits are interweaved in between to serve pedestrians and cyclists for safer and smooth travels. Poly-centric model also meant that the ‘‘center’’ is now dispersed throughout the site in contrast to just one center like the outer ring road model. The center, or core, within each of the clusters act as a provider for infrastructural services, accomodations, public amenties, as well as job opportunities to its adjacent villages. In return, the villages provide people and food crop to the core. Ultimately, the clusters are self-sustained. This change would help ease the congested city center by decentralizing services into a smaller scale in the periphery of the city, while the original center could continue serving the existing communities in the inner city area. The interaction points in the poly-centric model not only are more but also are more well distributed. When one of the points break down, there would be more options for alternative routes, with another service provider in a shorter distance compare to the previous model.
[ Outer Ring Road Model Breakdown Influence ]
Breakdown Point
Influenced Area
These series of diagrams demonstrate the size difference of the affected area when interaction points break downs in both the outer ring road circuit and the polycentric model. For the outer ring road model, three sets of interaction points were chosen for analysis: interaction points on proposed ring road, interaction points on national highway, and smaller junctions within the informal village roads. Less option for roads and public tranportation, when interaction points on ring road and national highway breakdown, large areas are affected. Another cause that aggrevate the impact of the breakdown for the outer ring road model is that the all the main service provider is located at the center of the circuit. So if networks leading to the center is interrupted, all the communities serviced by this network are affected.

[ Polycentric Model Breakdown Influence ]
On the contrary, polycentric model provide more than one service provider disperse around the site.Therefore, when on cluster is disrupted, its closest cluster center could be the temporary provider for the affected communities. Moreover, since there are more road options for different user group, negative impact reduces to minimum when breakdown occurs.

[ Distance From Village to Facility Provider Comparison ] By comparing the distance required to travel for each village to reach urban amenities, the efficiency of the two models, outer ring road and polycentric, could be visualized as the chart on the left. For the outer ring road model, the existing city center is the main provider for urban amenities, public infrastructure, as well as jobs. In order to access these services, communities at the periphery of the city would need to reach the city center by the only route option - the outer ring road. Since most of the villages outside of the ring are not immediately connected to formal roads, the time to travel from village to the ring could be lengthen. Moreover, the outer ring road does not provide different route options to cater different modes of transportation; Therefore, people are foreced to reach the city by car, which would not only lead to induced traffic but also putting the only connection to town at risk of congestion or even breakdown. Hence, the travel distance and time to access the services increase. On the other hand, for the polycentic model, each of the village is connected within their designated cluster with a core as service provider from within. Traveling long distance and hours to the center for amenities are no longer necessary in this case. As a result of more refined connections in small scale within each cluster, distance from each village to their service provider, or its core is much smaller. Within the smaller network, route options for other modes of tranportations are abundant. Since the distance are much closer, walking or cycling could be the options for most of the people to reduce car traffic. Distinctively, the polycentric model offer alternatives for communities to access. Because villages are closely knit from within the cluster and well connected in the larger scale, if one of the core breaksdown, people could easily travel to their closest cluster for services.
