This thesis project proposes an urban model solution to ease road traffic gridlocks and bottleneck junctions, by using an on-demand eDrone taxis with the aim of integrating the mobility network in a 3D urban grid. eDrone taxis are autonomous, electrical, affordable, environmentally friendly, offering flexible routes, and offer time saving solutions for transporting people from point A to point B in a matter of minutes. eDrone taxis are fully integrated with the existing road transportation network at the city level, achieving a more efficient road mobility network and thus providing more free land area which can be re-purposed, contributing towards a more self sufficient and sustainable urban environment.
Cities are dynamic, constantly in motion and transportation is fundamental to their social and economical development. From the historical times the means of mobility has evolved, we have come a long way from the invention of the stone wheel in 3500 BC to the 21st Century’s ‘wheel of autonomy’. As the technology advanced so did the options of transportation and the demand of the end user. Today the conventional modes of transportation are over exploited. The ratio of the number of vehicles on the roads and the capacity of the roads to carry vehicular traffic is unbalanced resulting into gridlocks i.e. road congestion, bottlenecks and traffic hotspots and road collisions. This also impacts the environment and the people living in close proximity.

WHEN?? 2001- 2015
WHERE?? European Union
Site Selection Criteria The study of gridlocks, traffic index, carbon emission with respect to the mode of transportation along a last few years in the continent of Europe will be useful to get a clear picture of the present situation and propose a solution for the problem. Thus it is important to study these statistics of the effects of conventional modes of mobility and its impact on their surroundings.
WHAT?? Issues Fatalties Carbon Emission Traffic Index
After studying the statistics it is important to find solution for the existing current situation. Urban resilience can be an answer but there is a need of completely different mode of mobility network which is environmental friendly, technologically driven, time saving, on demand and user friendly. The finalised Site is in the city of Hamburg City driven by the research.

A decade ago, driver-less cars seemed a little more than a futurist’s vision. Today, nearly every auto-maker and manufacturer is investing billions in their development. Likewise flying cars may seem like difficult to establish worldwide, the near future is ready to give the answers.

Using cardboard as the structural material the goal is to create a light weight pavilion. Pixels Pavilion is an honest effort to create a structure out of cardboard as a soul material. The methodology used was that of part to whole approach by creating modules and interlocking them to create a porous volume. To start with a basic square piece of cardboard is used to study and experiment the strength of the material it was evident that if the cardboard is folded against ribs it is stable and transfers the load equally from the ridge along the slopes. Also we switched from a square piece to a octagon because octagons have 50% efficiency with more edges and best inclination of 45’ for load transfer. (4/8 sides + 0.5 x 4 sides.) For the form finding a Cube with dimensions of 2500 x 2500 x 2500 mm in Length, Breadth and Height respectively is taken. This cube is then rotated on an angle of 45° on X axis. This cube is again rotated on an angle of 45° On the Z- axis to rest on the ground and form a base. A puncture is created by scooping out a portion to make the pavilion accessible. The key elements to the success of this pavilion is its part to whole approach, minimum material wastage, easy to fabricate the modules thus mass production is possible, optimized time consumption, Interlocking modules without the use of adhesives or fixtures gets stiffer with every added layer of modules and building Strategies.

Starting from the idea of how can we design and produce a chair that can be multifunctional only with the change in its position, this is how Animalitos was conceived. The design objective was to keep it simple and clean, such that the form accommodates multiple functions. The varying angles of the back rest were achieved by the base form designed. Exploring different positions that a chair can have; working, resting, or just sitting. Using Karamba as a tool, the structural and shell analysis played a role in form finding of the chair. The digital analysis and the physical testing of the chair made the fulproof of its stability. The final shape is a wooden skeleton made by five principal elements that are the main profiles, followed by ten secondary elements that are the ones that created the seat, or the supports, depending on which position the chair is.

The Chair
The design process is based on the structural analysis of the selected form in 2D frame. Conisdering the 2D frame as a beam the tests of bending moment and axial forces are carried out. The results for each positions are overlapped to get a 2D profile of the chair. The shell analysis is carried out to check the utilization and displacement of the 2D frame to check the stability of the frame. With the study of force flow lines and tension and compression lines the the location of the perforations is located.
The final shape is a wooden skeleton made by five principal elements that are the main profiles, followed by ten secondary elements that are the ones that created the seat, or the supports, depending on which position the chair is. The joineries are made with metal rods and nuts, situated in strategical parts of the chair; as it was mentioned, where the material can be removed, bringing to the chair the stiffness and rigidness needed so it can work. Because rawness is beauty as well, we decided to give this finishing to the final product, mentioning that we implemented ergonomics in order to understand the commodity of the user in each position, bringing Animalitos as the multifunctional chair.

Nowadays the notion of urbanism is in a full state of decay. As a result of fast urban growth without proper municipal planning, many cities are not able to absorb the dynamics of change, creating an urban fragmentation and lack of mobility infrastructure with poor pedestrianism and high vehicular traffic congestion. This urban fragmentation is irregular and arbitrary; it tends to separate the elements that conform a city. Can we create a new type of mobility in which the infrastructure acts as a strategic connectivity network for optimization of pedestrianism and public transport? The solution is to organize the urban fabric by intervening the actual site and generating an architectural proposal that establishes a direct dialogue between the existing and new infrastructure, static and dynamic spaces, layers of density, and urban and human scales, all of which will maximize the pedestrian and public transportation flow.
At the perinode we noticed two main features, the conjuctions of different levels of mobility, mainly the railway and highway, which greatly affected pedestrianism and vehicular traffic. They caused a huge barrier throughout each quadrant of the perinode the other thing we noticed were unused expanses, abandoned buildings and unused parking lots, all these spaces are not very developed, not very pedestrian friendly, but have potential of being a center of interest. The lack of pedestrianism and high vehicular traffic congestion due to lack of mobility infrastructure became fundamental to our argument and a base point for our project. that is, we wanted to create a futuristic and optimized mobility on the site. Instead of having the current vehicular-oriented mobility, we went the opposite and focused on a 100% car-free zone with pedestrianism and future drone public transportation. In order to do this, our aim was to optimize different tiers of travel through the site. we started by creating a grid system first by setting points of interest or entrance around the site every 0.25 km.

Our solution is to create a new type of mobility in which the new infrastructure acts as strategic connectivity network for optimal travel paths. The urban proposal is to create a 100% pedestrian and future public transportation city. The volumetric design is a continuous ground flow between densities, which maximizes the pedestrian and public transportation flow.

Gahininath Gadh was built in the late 16th century. Till date the followers come to seek blessings of the saint Gahininath and his disciples with the same belief and devotion in their minds body and soul. The plight is that today there is no proper coordination between the activities performed and facilities provided. Lack of open gathering spaces and pause points at regular intervals is one of the major issues, The result is that the devotees are forced to gather elsewhere during festive times. Administration also poses a problem as the social activities carried out by the trust are scattered. Monitoring funds, allotting spaces and maintenance becomes much more feasible within a campus. The project aims at providing a unified campus that encompasses all the activities of the temple complex as well as other services provided for the pilgrims and the locals. The spaces provided are functional, conceptual, climate responsive and have a humane approach. Thus, considering all the important aspects the proposed design is vernacular with a hint of modernity at the same time.
