This study examined the factors related to travel mode choices in the Dallas-Fort Worth Metropolitan Area. Changes in population, life style and economy of the Dallas-Fort Worth region over the last few decades demand a careful re-examination of travel demand tools and methods. The purpose of the study was to provide an understanding of transportation modal choice in the region. Those demographic variables best predicting the choices were identified. The Home Interview Survey, a set of disaggregate data from the 19 84 North Central Texas Council of Governments (NCTCOG) Regional Travel Survey, was analyzed using logistic regression. The major findings of the research indicate that about 97 percent of the travelers in the study area used private cars and 3 percent used public transit. Household income and cars-vans were significant explanatory variables. The impact of household income and number of car-vans available upon an individual's decision for travel mode choice were very important. The number of car-vans available in the household, and age of respondents were significant predictors in travel mode. Household members with incomes of $30,000 to $39,000 and those with incomes of at least $50,000 tended to use more private cars than did other income groups. Also, household members with incomes below $9,000 used more public transportation. People reporting a lower preference for cars were younger than 26 years or older than 55 years of age.

New York’s transit system serves millions of riders each day; the local newspapers complain about the lack of funding for infrastructure projects; and the City Council regularly hosts hearings about Bus Rapid Transit, bike-share, road safety, e-hail taxis, and gondolas. Transportation issues matter to New Yorkers, but these debates, at the policy level, often focus on technology, budgets, and regulations rather than the needs and experiences of passengers. This focus on “technical” matters allows planners and politicians to confine transportation debates to the realm of experts rather than engage the broader public in them. The failure to address the needs of passengers in Brooklyn and Queens has led to the development of dollar vans. Dollar vans are hybrid bus-taxis, also known as jitneys, that provide vital transportation links to more than 120,000 riders per day and operate beyond the control of the formal transit system governed by the Metropolitan Transportation Authority (MTA). While this ridership pales in comparison to the daily ridership on the subway or bus, it does rival bus ridership in cities like Dallas and Milwaukee and dwarfs the 50,000 peak ridership achieved by Citi Bike, New York’s celebrated bike-share system. More important, the durability of the vans reveals the failures of the existing formal system to serve all New Yorkers. I argue that this failure is important for three reasons. First, the vans respond to a geographically specific problem: adequate access to inadequate service. The vans thrive in busy transit corridors where MTA-owned buses come too infrequently, are overcrowded, or are regularly stuck in traffic. On these busy routes, the vans provide a more reliable ride and alternative for transit-dependent populations looking to bypass the faltering bus system. Second, regulations fail to reflect daily practice. This gap between practice and policy leaves van operators and passengers in an awkward limbo that criminalizes an industry and jeopardizes the mobility of entire neighborhoods. Third, since the vans operate outside of the formal system, traditional metrics, such as ridership, travel time, vehicle revenue miles, etc., are not collected and compared against the metrics of other modes operated by the MTA. As long as the vans remain an unknown quantity, it is impossible for the City and State to serve transit-dependent populations in Brooklyn and Queens. In this dissertation, I use a mixed-methods research design to probe the world of the vans and argue that continued regulatory uncertainty, long the friend of the vans, has the potential to upend them as development pressures and capital investment in Central Brooklyn intensifies.

This thesis explores the ways in which the concept of &ldquo / city junction&rdquo / has been considered as an element of the urban image within the network of circulation. The aim of this study is to make an historical analysis of urban transformation in In&ouml / n&uuml / Square at Ankara, instigated by the respect to recent traffic problem-centered nodal interventions in the area. Akay Junction, which is thought as 1930&rsquo / s representative space also having historical power as well as being a node where two significant axis intersect, is studied in its social, cultural and political context, through written and visual historical sources, with its relevant physical spatial components and relations to space and its nearby environment. Presenting the interactions within the historical process and considering the traffic based physical transformation, the role of the concept of city junction in the formation of urban public space in terms of architecture is questioned. Based on the material research the thesis presents the existing and the possible alternative models together with a proposal, regarding the further possible transformations especially with the extension planned for the underground rail transport to the area. The alternatives indicate the qualitatively different results that will be got with respect to providing a viable urban public space as such a node.

In recent decades skateboarding has expanded from recreation into a form of transportation. Skateboarders appear to use roadways much as other non‐motorized modes do. However, there is little academic research on the needs and characteristics of the skateboard as a mode. This research reports demographics, multi‐modal and travel behavior findings, and other data from an exploratory mixed‐methods study of skateboarding as a mode of transportation.

Thesis (PhD)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: Suburbanisation is a world-wide phenomenon and is characterised by the decline of central business districts and accelerated growth of commercial activities in the suburbs. The impact of suburbanisation is wide-spread and multi-dimensional, affecting the whole urban system in terms of its structure, activity and transport patterns. In South Africa, suburbanisation, together with the impact of the former group areas policy, has made suburban developments less accessible to the low-income groups living on the edges of the metropolitan area. Planners have proposed various urban densification strategies for the rather unique problems of the spatially inefficient South African cities, including corridor development along main public transport routes and the development of activity nodes. In order to implement these urban densification strategies successfully, it is important to understand the locational choice behaviour of business managers, and the factors that will attract them to locate in a certain area. This will enable metropolitan authorities to evaluate and implement the best policies to promote development of priority corridors and nodes The research for this dissertation was motivated by the extensive problems of suburbanisation, the lack of knowledge on the relative impact of land-use transport factors on the locational choices of businesses, and the apparent limited application of stated preference (SP) survey techniques and discrete choice models to spatial choices of businesses for urban planning purposes. The main objectives of the research were to determine the locational choice behaviour of retail businesses in strategic spatial terms, and how this knowledge can best be used to manage suburbanisation. The dissertation reviews intemational and South African studies on the planning and policies of the main role players in the urban system relating to retail suburbanisation, i.e. the planning authority, retail firms and consumers. The dissertation discusses the results of the market research that was done among Cape Town retailers located in the CSO, and in low- and high-income suburbs. The survey collected quantitative information regarding the locational choice factors of retail managers, importance ratings of choice factors as well as stated preferences for CSO and suburban locations. The calibration results of various discrete locational choice models are discussed, including elasticities of choice factors obtained from model applications to the SP data. The development of a spreadsheet locational choice model based on typical characteristics of CSO and suburban locations is subsequently discussed. Elasticities of choice factors from the application of the spreadsheet model were determined and the model was also used to test a decentralisation trend scenario and a managed suburbanisation scenario. The dissertation makes conclusions and recommendations regarding the most important locational choice factors of retail managers, and the most effective policies and strategies for metropolitan authorities to manage suburbanisation and promote urban densification. The performance of SP models applied to spatial choices are also evaluated and recommendations are made regarding their application and further research needs. / AFRIKAANSE OPSOMMING: Stedelike desentralisasie is 'n wêreldwye verskynsel wat gekenmerk word deur die verval van sentrale sakegebiede (SSG) en die snelle groei van handelsbedrywighede in voorstede. Die impak van desentralisasie is verreikend en multi-dimensioneel en beïnvloed die hele stadstelsel in terme van sy struktuur, aktiwiteite and reispatrone. In Suid Afrika het desentralisasie saam met die impak van die voormalige groepsgebiedebeleid voorstedelike ontwikkelings minder toeganklik gemaak vir die lae-inkomstegroepe wat op die rand van die metropolitaanse gebiede woon. Beplanners het verskeie stadsverdigtingstrategieë, insluitende korridorontwikkeling langs hoofvervoerroetes en die ontwikkeling van aktiwiteitsnodusse voorgestelom die unieke probleme van die ruimtelik ondoeltreffende Suid-Afrikaanse stede die hoof te bied. Om hierdie stadsverdigtingstrategieë suksesvol te implementeer, is dit egter belangrik om die liggingskeusegedrag van besigheidsbestuurders, sowel as die faktore wat hulle beweeg om hulle in 'n spesifieke gebied te vestig, te verstaan. Hierdie kennnis sal metropolitaanse owerhede in staat stelom beleid te evalueer en die beste beleidsopsies te implementeer om die ontwikkeling van voorkeurkorridors en nodusse te bevorder. Die navorsing vir hierdie verhandeling is gemotiveer deur die omvattende probleme wat deur stedelike desentralisasie veroorsaak word, die gebrek aan kennis oor die relatiewe impak van grondgebruik-vervoerfaktore op die liggingskeuse van besighede, en die klaarblyklik beperkte toepassing van verklaardevoorkeuropnametegnieke (V V) en diskrete-keusemodelle op die liggingskeuses van besighede vir stadsbeplanningsdoeleindes. Die hoofdoelstellings van die navorsing was om die liggingskeusegedrag van kleinhandelbesighede in strategiese ruimtelike terme te bepaal en vas te stel hoe hierdie kennis gebruik kan word om stedelike desentralisasie te bestuur. In hierdie verhandeling word 'n oorsig gegee van die internasionale en Suid- Afrikaanse studies oor die beplanning en beleid van die belangrikste rolspelers in the stadstelsel wat desentralisasie van kleinhandel betref, naamlik die beplanningsowerheid, kleinhandelfirmas en verbruikers. Die resultate van marknavorsing onder kleinhandelaars vanuit Kaapstad se SSG en lae- en hoë-inkomstevoorstede, word bespreek. Die opname het kwantitatiewe inligting oor die liggingskeusefaktore van kleinhandelaars, die belangrikheid wat hulle aan keusefaktore heg, en hulle verklaarde voorkeure ten opsigte van vestiging in die SSG of die voorstede, ingesamel. Die kalibrasieresultate van verskeie diskretekeusemodelle word bespreek, insluitende die elastisiteite van keusefaktore wat deur die toepassing van die modelop V V-data verkry is. Vervolgens word die ontwikkeling van 'n liggingskeusemodel in 'n spreitabel wat op tipiese kenmerke van SSG- en voorstedelike liggings gebaseer is, bespreek. Elastisteite van die liggingsfaktore is bepaal deur die toepassing van die spreitabelmodel, en die model is ook gebruik om 'n desentraliasietendensscenario en 'n bestuurdedesentralisasiescenario te toets. Ten slotte word daar gevolgtrekkings en aanbevelings gemaak oor die belangrikste liggingskeusefaktore van kleinhandelaars, en die mees effektiewe beleidsopsies en strategieë wat metropolitaanse owerhede kan volg om stedelike desentralisasie te bestuur en stadsverdigting te bevorder. Die werkverrigting van V V-modelle wanneer dit op die liggingskeuse van besighede toegepas word, word ook geëvalueer en aanbevelings word gemaak oor die toepassing daarvan en verdere navorsing wat nodig is

Urban transportation networks are inefficient due to sub-optimal use by travelers. One approach to counter the increase in urban transportation demand is to provide better information to travelers, which would allow them to make better use of the network. Existing traveler information systems do this to a certain extent, but are limited by the data available and the scope of their implementation. These systems are vertically integrated and closed so that using any external elements for analysis, user interfacing etc. is difficult. The effects of such traveler information systems are reviewed via a comparative analysis of case studies available in the literature. It is found that information availability has a definite positive effect, but the social and environmental benefits are difficult to quantify. It is also seen that combining data by integrating systems can lead to additional uses for the same data and result on better quality of service and information. In this thesis, a regional platform for multi-modal traveler information is proposed that would support the development of traveler information systems. The architecture incorporates a central processing and storage module, which acts as an information clearinghouse and supports receiving, managing and sending data to and from multiple sources and interfaces. This setup allows sharing of data for analysis or application development, but with access control. The components are loosely coupled to minimize inter-dependencies. Due to this, the source, analysis, user interface and storage components can be developed independently of each other. To better develop the requirements and understand the challenges of the proposed concept, a limited implementation of the system is designed for the midtown Atlanta region, incorporating multiple data sources and user interfaces. The individual elements of the system are described in detail as is the testing and evaluation of the system.
