The spatial impact of smart mobility solutions

The spatial impact of Smart Mobility solutions Exploring the spatial impact of Smart Mobility solutions on the existing urban structure in cities The Smart City movement has gained popularity powered by technological innovations.

Smart Mobility solutions are one of the main facets of a Smart City, and many new technologies are being developed and applied . This research provides an overview of various Smart Mobility solutions and the spatial consequences of these solutions on the existing urban structure in cities using ďŹ ve research methods : literature review, trend analysis, interviews, policy analysis and data analysis . Six Smart Mobility solutions have been analysed which include Bike!Sharing, Car!Sharing, Autonomous Vehicle, Public Transport, Electric Vehicle and Multi!Modal Mobility. The short term spatial impacts of these solutions are li&le as they only slightly reduce the current parking pressure, and the infrastructure for Electric Vehicles is not aesthetically pleasing. However, the long term spatial impacts are positive as they will reclaim space used for street!parking and perhaps even parking garages . For older cities these innovations provide an opportunity to, at least partially, return the city to its original structure . The innovations will free up space mostly in the city centre which can be used to accommodate pedestrians and contribute to a higher quality of life .

1. Introduction The first ideas on smart cities came about in the 1850’s and started growing in popularity soon after. From the very beginning both sustainability and the use of new technologies were key to develop smart cities. One of the most wellMknown concepts is that of the garden city by Sir Ebenezer Howard dating from 1898, which was a vision on a healthy and functional city opposing the cities of the early industrial revolution (Angelidou, 2015) . New transport solutions such as the railway and the automobile made it possible to live away from the city in a more sustainable seYing . Table 1 shows how the Smart City concept has developed over time .

Table 1.Historical over view of the Smart Ci ty con cep tbased on (Angelidou, 2015) 1850’s First ideas on Smart Cities 1898 Garden City concept by E . Howard, focus on healthy versus industrial 1904 T . Garrier: ‘Une cite industrielle’, includes newest technology advances such as hydropower 1909M1916 Futurist movement, focus on machines and industry 1919M1932 Bauhaus, focus on mass industrial production 1922 Le Corbusier’s ‘Ville Contemporaine’, using new construction materials 1939 Bletchley Park, United Kingdom, first intelligent city using knowledge and information in spatial proximity (Komninos, 2011)

Post WWII New Towns movement, planned cities using new materials and construction methods 1960’s New technologies inspired thinkers and designers:‘PlugMin City’ (P. Cook), ‘Walking City’ (R . Herron), ‘Electronic Urbanism’ including teleMworking, Mcommunication and Mspaces (T . Zenetos) 1980’s Use of terms such as ‘Networked City’, ‘Cyber City’, ‘Intelligent City’, ‘Digital City’ etc .

1990’s Internet causes globalization, which will result in the disappearance of physical cities. Birth of Smart City term 1991 First mentioning of the Internet of Things Mid 1990 The future city will have ICT as city management 2009 Smart City becomes central theme in the development agendas of large cities Global hubs of innovation, knowledge Now management is everywhere . Small scale Smart City pilots, driven by a technology push and a demand pull Many researchers state that there is no agreed definition of the term Smart City in literature (Angelidou, 20 15; Cuddy, et al ., 2014; Grip, 2015; Hollands, 2008; Knowles & Rozenblat, 20 16; Lee, Hancock, & Hu, 2014; Letaifa, 2015; NeiroYi, et al ., 2014), which hinders literary research as it is difficult to compare different research

results. A distinction can be made between two main approaches. The first approach, most prevalent in literature, focusses on the implementation of information and communication technologies (ICT) at different scale levels .Peter Hall, a well¿known town planner and urban geographer, described the ‘Smart City’ as the result of an increasing complexity due to material wealth and communication technology and characterized by a shift from an economy based on production to one based on consumption (Knowles & Rozenblat, 2016) . Whereas Grip (2015) sees the Smart City as the collision between two trends : digitalization and urbanization, resulting in an extra digital layer onto the existing infrastructure.

Hollands (2008) has a similar view as according to him ‘smart’ implies a positive urban¿based technological innovation . NeiroÔi, et al . (20 14) state that the Smart City uses ICT based solutions to improve sustainability, but also invest in human capital . Letaifa (20 15) takes a more neutral stance, describing the Smart City as using technology, or at least moving in a forward way . Lee, et al . (2014) oppose this as they state that ICT is key in all concepts and variations of the Smart City .

The second approach focusses on the quality of life, working with existing solutions and communities.

Marsal¿Llacuna and Segal (in press) argue that a Smart City will not become the best based on technology, but by optimizing resources, efficiency, environmental protection and including social factors. Joris Scheers, a spatial planner and sociologist, claims that the Smart City is about listening and acting in a community¿ sensitive way (Grip, 20 15) . Whereas Cuddy, et al . (2014) recognize the potential of ICT, as it can provide insight into, and control, the various systems, they also stress the importance of focussing on quality of life.

Finding a shared definition is difficult, not only because different cities have different contexts (NeiroÔi, et al ., 2014), but also because Smart Cities can be seen as hybrid between different city types that originated in

the 1980’s (see Table 1) (Lee, et al ., 20 14) . Letaifa (2015) suggests that the Smart City is a hybrid between the intelligent city, with a top¿down approach focussing on technology, and the creative city, with a boÔom¿up approach focussing on community based solutions.

What all of the definitions have in common is a focus moving forward and using sustainable solutions to generate economic opportunities.

The Smart City can be divided into different facets.

Giffinger, Haindlmaier & Kramar (20 10) distinguish six different facets : Smart Economy, Smart People, Smart Governance, Smart Mobility, Smart Environment and Smart Living . Literature indicates that Smart Mobility is most prevalent in current cities (Hollands, 2008; Lee, et al ., 2014; NeiroÔi, et al ., 20 14; Letaifa, 20 15) . This is because technology in this field is more mature (NeiroÔi, et al ., 2014) .A variety of applications is already available to indicate vacant parking spots and real time traffic information (Mazhar Rathore, Ahmad, Paul, & Rho, 2016) .

Our daily paÔerns of movementsaremuch morecomplex than 60 years ago: people move further away from home and most travel occurs between cities (Nabielek & Hamers, 20 15) . Existing research focusses on various aspects of Smart Mobility such as computer modelling to increase traffic flow, autonomous vehicles (Zhang, Guhathakurta, Fang, & Zhang, 2015), multi¿modal transport solutions, the impact of electric vehicles on the Smart Grid (Calvillo, Sánchez¿Miralles, & Villar, 2016), fleet management (Horn, 2002), demand responsive transport (Horn, 2002), car¿sharing models, the use of renewable energies as fuels, and Smart City policies (Angelidou, 2014) . And though some mention that Smart Mobility innovations have spatial consequences (Hollands, 2008; Angelidou, 20 14; Ricci, 2015), none describe what these spatial consequences entail .

Especially in the western world, where there is no need for new cities but where existing cities are regenerated

(Angelidou, 20 14), these innovations can have a great impact on the existing urban structure. Therefore more research is required in this field, so the creation of Smart Cities can happen in a controlled and well designed manner . This has to happen simultaneously with research into Smart City solutions to prevent cities from becoming a hodgepodge of different technologies after their implementation .

Smart Mobility solutions can be applied at different scale levels .Giffinger (20 10) describes Smart Mobility as the accessibility on a local and (inter)national level, with the availability of ICT infrastructure and sustainable, innovative and safe transport systems. Table 2 gives an overview of the most commonly described solutions that will be used as a theoretical framework throughout this article, to describe the spatial implications of these solutions. It is important to note that they cannot be viewed separately, as often, multiple solutions are implemented simultaneously.

This article aims to give an overview of the (possible) spatial impacts of various Smart Mobility solutions by answering the following research question : How do Smart Mobility solutions affect the urban structure in existing cities?

In order to answer this question, five different methods of research were chosen : literature review, trend analysis, interviews, policy analysis and data analysis.

In this research, only existing information and data has been used .

The results from this research will not only clarify the spatial impacts of the various solutions, but will also serve as a guide for policy makers and urban planners who are developing Smart Cities .

2. Methodology Research approach This research aims to define the spatial consequences of six Smart Mobility solutions. These solutions (see Table

2) came forward from an extensive literature review and will function as a theoretical framework throughout this article. Information derived from the research methods will describe the spatial influence of these solutions.

For this paper secondary research has been done, as the information and datasets were already available.

This research, however, combines existing research at a higher level of abstraction through a meta=analysis.

Methods Five different methods were chosen to determine the spatial consequences of the six chosen Smart Mobility solutions. All methods will be discussed shortly, describing both advantages and disadvantages . As no direct research has been done into this topic, the different methods containing indirect clues on the spatial consequences are combined .

Literature review An extensive literature review provides information on current developments in science. Recently, a lot has been wriGen on Smart Cities, how they should be ranked (Giffinger, et al., 2010), and how to create them (Angelidou, 2015) . Within this field of Smart Cities, a lot is being said on Smart Mobility solutions .It is especially interesting to see Smart Mobility solutions that have not been (fully) implemented such as the Electric Vehicle and its charging infrastructure, the Autonomous Vehicle, and new methods of arranging Public Transport . Literature discusses technical aspects such as modelling software and related problems, but also explore how upcoming services such as Car=Sharing and Bike=Sharing can be optimized .

The initial literature review resulted in the six Smart Mobility solutions described in table 2 . The more in depth literature study that followed resulted in spatial outcomes of such solutions. For this, journal directories such as ScienceDirect (www .sciencedirect .com) and the

online library of Eindhoven University of Technology have been used to find relevant articles. The initial literature study also provided keywords which were used to find more information on specific topics. The articles scanned for relevant information, and then labelled based on which of the six Smart Mobility solutions it provided information on .

Trend analysis The Trend analysis provides information on which solutions and developments within the field of Smart Mobility are seen as interesting and upcoming. The usage of various solutions is interesting as this indicates what is trending for users, but also for businesses . A different perspective is provided by looking at what is trending in the research and development field where scientists and corporations are working on new Smart Mobility solutions. Traditionally, trend analysis looks at data over a period of time to observe trends. However, Smart Mobility is such a new topic, that its spatial consequences are not yet known and neither are historical trends. Articles predicting future developments therefore form the main source of information for this analysis.

Interviews Existing interviews have been used to provide various perspectives on Smart Mobility. These interviews have been conducted by the chief editor of Infrasite at e Keet . nl (e Keet .nl, 2016) . The topics of the interviews vary depending on the specializations of the interviewees.All interviews have been obtained via the Infrasite website.

Interviews are a qualitative research method, used to obtain descriptive information .One of the disadvantages is that the interviewee is (unconsciously) influenced by the interviewer . It is therefore very important that the interviewer is well trained to minimize this influence.

As the interviews were obtained from a blog, the skills

of the interviewer are unknown which can decrease the validity of the outcomes. Another disadvantage is that interviewees may favour a politically correct or socially desirable answer over the truth . However, due to the nature of the questions in the interviews, which are focused on facts and future speculation, and do not include any controversial topics, both disadvantages are expected to have had li£le effect on the results.

Policy analysis Policies of three Dutch cities; Amsterdam, Eindhoven and Utrecht, have been analysed to find existing Smart Mobility solutions, current developments and how these are being implemented . Some of the cities also have future goals which include Smart Mobility solutions, which have been included as well . This provides indirect information on spatial implications of these transport solutions. It also shows the perspective of the policy makers and city planners on what their view on the future city is. This source will mainly provide information on current available technologies and their implementation .

Data analysis The data analysis will provide information on the usage of Smart Mobility solutions, and indicate the preferences of users. The data can also indicate shifts in usage due to the implementation of a certain solution or innovation . Existing data sheets have been analysed, together with a dataset provided by KiM Netherlands Institute for Transport Policy Analysis (Hoogendoorn Lanser et al ., 2014) . Excel and SPSS have been used to analyse the data .

3. Results The spatial impact of Smart Mobility solutions depends greatly on the existing urban structure of the city.

In 1947 barely 1 in 10 families had a car (Hall, 1989) .

In the 1960’s the car became widely available and cities (or neighbourhoods) built from this period on have been designed with a prominent role for the car (Marsal×Llacuna & Segal, in press). Older cities, which have been designed for pedestrians and other forms of non×motorized transport, have been invaded by cars affecting the original design and structure .

A general tendency towards more efficient space use can be observed . Grip (20 15) predicts that most spaces will be hybrid and serve multiple functions either simultaneously or at different times during the day .

Literature review Bike×Sharing has existed for around 50 years, but has grown exponentially over the last decade (Bree, et al ., 20 10; Corcoran & Li, 20 14; Ricci, 20 15). The system differs from bike rental as it is used for short point to point journeys (Ricci, 20 15), creating a spatially dispersed difference in supply and demand that varies during the day . More bikes and docking stations are needed to cope with this growing demand, and whereas now the docking stations are usually next to public transport terminals, Bree, et al . (20 10) found that there also is a desire for other locations. They also highlight the issue of availability of space, as in some locations, particularly at large public transport terminals, there is no space to expand .

In general, the shared bicycle is part of a multi×modal journey that includes other forms of public transport, which in most cases use one integrated Smart Card for all different modes (Ricci, 20 15). Bree, et al . (20 10) do mention that even with a Smart Card, this intermodal transition needs to be smoother . Future technologies will generate ‘Smart Bikes’ with GPS and pollution and noise sensors which can provide real time data and information through an app (Marsal×Llacuna & Segal, in press).

Car×Sharing also grew exponentially over the past

two decades. There are three main business models: business to consumer (B2C) with a fixed parking spot, business to consumer with a ‘free floating’ system, and peer to peer (P2P) Car×Sharing using apps and websites where people can sign up their own car for sharing (Dieten, 20 15; Driel & Haÿamp, 20 15; Schmöller & Bogenberger, 20 14). The growing popularity can be partially a ributed to the flexibility of having access to a car without having any fixed costs and burdens (Baptista, et al ., 20 14; Dieten, 20 15; Glo ×Richter, 20 12).

Literature appears very positive about the influence of Car×Sharing in reducing parking demand and congestion (Dieten, 20 15; Kaspi, et al ., 20 15), some stating that one shared car replaces anywhere from 3 to 11 privately owned cars (Baptista, et al ., 20 14; Driel & Haÿamp, 20 15; Glo ×Richter, 20 12; Loose, 2009) . It is questionable whether these numbers are correct, as it is difficult to measure . Car×Sharing replaces a privately owned car for 90% of the users (Glo ×Richter, 20 12), but it often replaces a second car or other modes of transport which is more difficult to measure (Baptista, et al ., 20 14; Nijland, Meerkerk, & Hoen, 20 15) . It becomes even more speculative when people who never owned a car but might have bought one if they did not start Car×Sharing are included .Driel & Haÿamp (20 15) claim that including this group of people every shared car will replace 9×22 privately owned vehicles.

In theory however, this would create a lot of space, especially in the city centre . In the city of Bremen, 1500 cars have been replaced by Car×Sharing in one year (Glo ×Richter, 20 12). Loose (2009) states that in theory the replacement of 4×8 cars would free up 36×84m2 of space . Combining this information suggests that in one year 13500m2, or roughly two football fields, has been freed due to reduced parking demand . Loose (2009) already mentions that though in theory Car×Sharing should reduce parking pressure, in city centres the demand is so high that other cars take up the ‘free’

spaces . Driel & Ha amp (20 15) confirm this by stating that Car&Sharing does not necessarily lead to fewer cars .

One of the most promising Smart Mobility solutions is the Autonomous Vehicle .Though the technology is there in principle, some hurdles, such as safety, still have to be overcome . Siemens (n .d .) describes the implementation of the Autonomous Vehicle as a three step process . First there is ‘connected transport’ in which for instance the users smartphone is connected to the car system . Second is the ‘Co&operative Intelligent Transport System’ where

the vehicle communicates with other vehicles and the infrastructure, in this system the vehicle can brake

and park itself without human input, up to the point where only limited human input is needed . Third is the Autonomous Vehicle in which no human input is required at all .Alessandrini, et al . (20 15) have visualized a similar process in Figure 1.

The increased automation will lead to a less private relation to the car (Glo;&Richter, 20 12) . This provides

great potential for the Autonomous Vehicle to create a synergy with Car&Sharing . Such Shared Autonomous Vehicles are like a taxi on demand (Fagnant & Kockelman, 20 15; Zhang, et al ., 20 15) . These vehicles will have a tremendous spatial impact as they can be parked in depots which takes up only a quarter of the space of a regular garage (see Figure 2) . One Shared Autonomous Vehicle is said to replace 11 privately owned cars (Zhang, et al ., 20 15), but like regular Car& Sharing it is unlikely that it will result in less cars .

Fagnant and Kockelman (20 15) argue that there will be a higher demand and wider user base, as the elderly and children are able to use such vehicles as well . Also, Autonomous Vehicles are much more efficient than regular cars as they do not ‘cruise’ looking for free

Figure 2 . Con ven ti onal garage vers us a uton om ous car dep ot (Alessan drini, e t al ., 2 015) Current developments in Public Transport focus on more efficient transportation using special bus lanes (Debnath, et al ., 20 14), and transitioning to the use of electricity as a power source (Calvillo, et al ., 20 16) .

Electric Vehicles, though at the moment not widely used, will replace most of the carbon fuelled vehicles in the coming decades (Loose, 2009) . A synergy with B2C Car&Sharing using fixed parking places is easily found as these parking spots can be fiued with the required charging infrastructure . Currently only 9% of the vehicles used in Car&Sharing are electric leaving much room for growth (Baptista, et al ., 20 14) .

can be auributed to an increased demand for individual mobility due to varied lifestyles, increased importance

of leisure activities and liberalization of working hours and conditions (Alessandrini, et al ., 20 15) .

Bike Sharing is growing in popularity, and demand increases especially at public transport terminals (Nabielek & Hamers, 20 15; NS, 20 16) . A payment system

A development that is still trending and widely applied is the use of renewable energies for transport fuels (Neiro½i, et al ., 20 14) . Currently the focus is primarily on business related drives who account for 95% of

Public Transport and especially MultiéModal Mobility , should be developed further (Boerrigter, 20 15; Meijl, 0 15) as it offers alternative travel options during rush 2 , hour (Schulõ van Haegen, 20 13), and though it is more expensive, it has a large capacity (Weijer, 20 15) .

Electric Vehicles are to replace existing vehicles for Public Transport with the primary goal to reduce

the city centre (Gemeente Eindhoven, 20 13; Gemeente Amsterdam, 20 13; Mansveld, 20 15) . Subsidies are used as an incentive for people to use clean transportation

emissions (Schulõ van Haegen, 20 13) . One problem is charging these busses as they are always moving .

However, it is possible to install wireless chargers at bus

stops, so that at every stop the bus charges a liýle (Meijl, 0 15) .

2 Lievense ( 0 13) stresses that though Electric Vehicles 2 are a good start, conceptually we should look beyond to other possibilities . Schulõ van Haegen (20 13) agrees by stating that it is most important to keep options open for further development, and not to change the infrastructure in such a way that it only facilitates one technology .

Policy analysis Policies tend to focus on pedestrians and other forms of nonémotorized transport such as bicycles (Gemeente Eindhoven 0 13; Gemeente Utrecht 0 15a) . A new , 2 , 2 concept in policy making is the use of hybrid spaces, for example space used for delivery trucks in the early morning and terraces in the afternoon (Gemeente

Amsterdam, 20 13) . BikeéSharing, more facilities to accommodate bikes and the integration with a Smart Card for payment are seen as important (Cuddy et al . , , 0 14 G 0 13) .

2 ; emeente Amsterdam, 2 One of the common goals is to reduce the amount of cars in city centres . This is done by actively promoting CaréSharing (Cuddy et al . 0 14; Mansveld 0 15; , , 2 , 2 Ministerie van Economische Zaken, 20 15; Waard & Meijles, 20 15), and reducing the amount of parking in

methods, such as CaréSharing, Public Transport, Bikeé Sharing and Eébikes instead of fuel powered vehicles ,

(Waard & Meijles, 20 15) .

A seamless connection to Public Transport is seen as key in the city centre (Gemeente Utrecht, 20 15a) .

For 2 ; M n ster e van conom sche Za en, 2 Public Transport a fast charging system at bus stops can ensure that the vehicle is fully charged at the end of the line (Cuddy, et al ., 20 14) . A possible technology for this, which also has great potential for CaréSharing, is inductive or wireless charging which can be integrated invisibly (Filho & Koýer 0 15; Mil et al . 0 16) avoiding ,2 , ,2 , the “significant diversification in townscape” caused by conductive charging stations (Filho & Koýer, 20 15) .

Data analysis There is a greater demand for all types of vehicles including bikes Eébikes mopeds cars Electric Vehicles , , , , , and motorbikes, but also a greater use of Public Transport (CBS, 20 15; Gemeente Utrecht, 20 15b; KiM, bike 0 15 ) C li i 2 a . yc sts have expressed the des re for fast lanes in the city of Utrecht the Netherlands (Gemeente , Utrecht, 20 15b), which is not surprising as the bike is the

most popular way of transport for short distances (see Figure 3) (CBS 0 15; HoogendoornéLanser et al . 0 14) . ,2 ,2 The data on CaréSharing appears contradicting . Caré Sharing replaces other modes of transport such as the

privately owned car (40%), train (35%), or is a ride not done without the availability of the service (16%) (KiM, 20 15b) .Yet 65% of the users of Car=Sharing services have

a Public Transport plan, as opposed to 35% of the non= users (Gier & EEema, 20 14), which suggests they use Public Transport more . Different datasets do find some commonalities . Car=Sharing users drive less kilometres

various policies, though Car=Sharing also is a popular topic . The datasets used mostly provided information on Car=Sharing, and the use of other transport modes as it is limited to currently employed technologies .

Answering the second research question How do these Smart Mobility solutions aff ect the urban structure in existing cities ? requires a more elaborate approach .

on average (KiM, 20 15b) . 50% of the users do not own a car, and for 37% the service replaces a second car (Gier & EEema, 20 14; KiM, 20 15a) .

Though the KiM (20 15a) admits that liEle is known on the effects of Car=Sharing, it does bring out some interesting estimations on the service . As of 20 15 120 .000m2 of

The increasing popularity of Bike=Sharing requires expansion of the existing docking stations and the implementation of new ones . At some locations this

parking spaces have been ‘freed’ due to Car=Sharing, as one shared vehicle replaces 4=8 privately owned and up to 36=84m2 parking space .Shared vehicles take up equal

space as regular cars, but are used 62 minutes a day on average as opposed to 30=45 minutes . So privately owned vehicles spend more time idle, but this piece of data suggests that one shared vehicle replaces two privately owned ones .

Surprisingly 88% of drivers in the morning rush hour , drive alone, and 80% in the evening rush hour (CBS, 20 15) providing great potential for ride=sharing . , Comparative analysis It is interesting to note that information on the six Smart Mobility solutions is not equally distributed among the different research methods . Literature focuses on Bike=Sharing and Car=Sharing systems but also on the , technical aspects of the Autonomous Vehicle and the Electric Vehicle . The trends mostly concern Bike=Sharing

and Car=Sharing whereas the Autonomous Vehicle is limited to tech companies and car manufacturers . The interviewees described the Autonomous Vehicle to have a lot of future potential . For now, however, the main focus is on optimizing Public Transport and Electric Vehicles . A similar viewpoint as can be observed in

expansion can be problematic as there is liEle physical space to expand, which would imply taking away space from pedestrians to accommodate this growth .

Modality requires that docking stations are in easy reach of other modes of transport .

A lot of the information on Car=Sharing appears false or somewhat contradicting .It is especially unclear whether Car=Sharing leads to a reduction of cars on the road and a decrease in parking pressure . Assuming that it does have a certain impact, albeit not as big as suggested, Car=Sharing has the potential to affect the city structure in a positive way . This is especially the case for older cities, in which the reduced number of cars can be compensated by reducing the number of road=side parking spots, restoring the original street scape and freeing space for pedestrians and cyclists . Naturally , these effects will grow as Car=Sharing gains popularity .

A successful ride=sharing system could enhance this effect tremendously .As 88% of cars during the morning rush hour and 80% during the evening rush hour have single occupancy, ride=sharing has a vast potential to not only reduce the amount of cars on the road, but also the amount of privately owned cars .

The Autonomous Car can possibly fulfil this role by creating a synergy with Car=Sharing . In a perfect world where everyone uses Shared Autonomous Vehicles

there would be no road side parking, cars cruising for parking or traffic jams . Cars will be parked in large depots outside of the ity entre whi h frees up not only c c c space currently used for road side parking, but also (underground) parking garages .

Of ourse reality will never be like su h an utopia and c c , even the large scale implementation of the Autonomous Vehi le will take de ades . But developments towards c c the Autonomous Vehicle will have spatial impacts in a shorter time span . The Co operative Intelligent Transport System provides the technology through which cars park autonomously, and hence can be parked closer to each other which can create more space in parking garages to repla e street parking . Real time c information on available parking pla es an redu e c c c ising reating more spa e on the roads themselves . r u c ,c c 4. Conclusion The Smart City is a trending topic and many of its facets are being researched . Not only does it include technological innovations, but the use of human capital and focus on the quality of life are key aspects of creating a Smart City .

Within the field of Smart Mobility six solutions are often

des ribed in literature and these have been taken as the c , theoretical framework . They are in no specific order : 1.

Autonomous Vehicles Public Transport Electric Vehicles / Bikes Multi Modal Mobility

These solutions cannot be seen separately, as they function like a Venn diagram, with many touching and overlapping elements .

Though all solutions within the framework were des ribed throughout the various resear h methods c c , Multi Modal Mobility does not appear to have any

dire t spatial impa t other than influen ing the lo ation c c, c c of other solutions such as docking stations for Bike Sharing . It operates more as a connective element between the different modes of transport . The Ele tri c c Vehi le in most ases forms a synergy with one of c c the other solutions . However, it does have a direct spatial impact due to the charging infrastructure that is required proving it to be a relevant ategory . The , c remaining four categories concern the main modes of transport: the car, bike and Public Transport .

An additional Smart Mobility category that has not been des ribed above is the pedestrian as walking is a form of c transport . Furthermore, in the city centre the pedestrian is the main fo us of poli y makers and this will likely c c in rease in the future . Other Smart Mobility solutions c will not only reduce the amount of cars, but will also make transportation more efficient .For older cities these innovations provide an opportunity to at least partially , , return the city to its original structure . The innovations will free up space mostly in the city centre which can be used to accommodate pedestrians and contribute to a higher quality of life .

This research provides a first step in discovering the spatial impacts of Smart Mobility solutions . Though more research is required so that policy makers, urban planners and others working on the implementation of Smart Mobility solutions know beforehand what the spatial consequences of these solutions will be . Ideally this information will be gathered in a comprehensive modelling tool .

It is essential to obtain more information on the effects of these Smart Mobility solutions on usage . Currently this information is un lear as an be seen with the results c , c of Car Sharing which, in theory, should lead to a great reduction in the amount of privately owned cars and parking demand, but clearly fails to do so .Technological innovations within other fa ets of the Smart City an c c perhaps be used to gather such information .

Another crucial knowledge gap is how these Smart Mobility solutions affect the quality of life in a city , which is relevant for policy makers and urban planners working on the Smart City . The same can be said for the other Smart City themes as described by Giffinger, Haindlmaier & Kramar (20 10) . Though they describe Smart Living as the determining facet for quality of life, it should not be underestimated how much the other facets affect this too . It is of paramount importance to know the different impacts of these facets in order to design the cities of the future successfully .

5. Acknowledgements In this publication I made use of data from the Netherlands Mobility Panel administered by KiM Netherlands Institute for Transport Policy Analysis .

The MPN is a household panel, which main objectives are to establish short run and long run dynamics in travel behaviour of individuals and households, and to determine how changes in personal and household characteristics and in other travel related factors (e .g . economic crisis, reduced taxes on sustainable transport,

changes in land use or increased availability and use of ICT) correlate with changes in travel behaviour (see Hoogendoorn Lanser et al . (20 14) for more details) .

Starting July 20 13, respondents 12 years or older from 2 500 complete households recorded their travel data , using a three day travel diary . For each respondent, the diary provided information about all trips (stages) the respondent had taken (transport modes, trip purposes, travel companionship, delays, parking costs) . Between

20 13 and 20 16 this will be repeated at least yearly , with the same respondents . At the same time different , questionnaires were filled out offering a large amount of background information on respondents and their households .
