Why did Melbourne keep its trams, especially during the 1950s and 1960s when other Australian capital cities, the major cities in New Zealand, the UK and Ireland, and most US and Canadian cities didn't? Melbourne now has the largest tramway system in the world, as measured by route length, though not by passenger numbers. This paper will explore how the automobile clubs and bus lobbies campaigned to get rid of trams. What is it in Melbourne's topography and political culture which enabled its tramway system to survive, while Sydney, with a bigger system, closed its entire network? Cities abandoning their trams promptly turned to buses. Only a handful of 'heritage' tram lines survived, though there is now a resurgence of light rail in some cities, and of all places, on the Gold Coast. The paper will set the analysis in the context of the coming of mass car ownership in the 1950s and 1960s, and the apparent attraction of getting rid of trams in the name of modernity.

The disutility of transfers in multimodal public transport goes beyond the additional walking and waiting times. Although the magnitude of this pure transfer penalty has been proven to be an essential element in the structural design of public transport lines, the scarce available research reveals a wide range of values. The aim of this paper is to develop and apply a framework to estimate the value perceived and assigned by commuters to this penalty. This framework includes all the other elements considered by users in the case of a trip involving (potential) transfers, in order to obtain the impact of each one. The framework is based on the discrete choices paradigm and applied to data collected in Madrid, Spain. The results show that the pure transfer penalty is comparable to a 15.2-17.7 equivalent increase in in-vehicle minutes; i.e. longer trips may be preferred to faster alternatives with transfers, even if the additional walking and waiting times are zero. As well as the pure transfer penalty, the model also captures the effects of habit, crowding, walking, waiting and in-vehicle times, information, and the additional effect of intermodality on transfers.

As it is considerably difficult to identify specific changes by using a single numeric parameter, improvements gained by a new urban public transport (UPT) facility or by an operation policy is still a challenge in the decision-making process with respect to transportation planning. Although some indicators such as service quality, capacity usage ratio, service kilometers, passenger kilometers or seat kilometers are used by planners and policy makers, these indicators may not always reflect the total gain of trip makers: to access a facility providing a specific utility. Thus, this study aims to evaluate accessibility measures as performance indicators in the UPT planning process. Three scenarios that consist of timetable regulation, central business district restriction and integration with bus rapid transit are investigated using accessibility perspective in addition to the conventional indicators obtained by using VISUM™ travel demand modeling software. The results show that the first scenario leads to a more effective UPT system in terms of accessibility. Hence, a more distinctive measure is obtained for the decision stage of UPT planning.

El problema de la movilidad urbana en el actual modelo de crecimiento de las grandes ciudades puede considerarse como uno de los grandes retos políticos del siglo XXI. En este contexto, el sistema de transporte tiene que desarrollar sus estructuras sobre un territorio fragmentado institucionalmente, de manera que los ámbitos territoriales de las redes de transporte y de las instituciones político-administrativas que ejercen el poder no siempre coinciden. El problema se centra en crear una oferta única y coordinada de transporte colectivo para el conjunto del ámbito metropolitano en las grandes ciudades puesto, que de forma espontánea, no se regula. Entre los usuarios finales y las empresas operadoras que suministran el servicio se encuentran las autoridades: Centrales, Regionales y Locales, que regulan la organización del transporte, con la creación de organismos propios que asumen las responsabilidades en materias de transporte En España, la Ley Reguladora de las Bases de Régimen Local LRBRL, (Ley 7/1985), considera el transporte urbano colectivo como un servicio público de obligada prestación por parte de los ayuntamientos en sus respectivas áreas de influencia territorial. En este contexto, los servicios públicos locales, incluido el servicio de transporte colectivo urbano, pueden gestionarse de forma directa o indirecta, por sí mismos, o en asociación con otros municipios. En este trabajo, se analizan las diferentes formas de gestión y organización de los servicios públicos de transporte de viajeros para caracterizar los modelos de las principales ciudades españolas. Partiendo del concepto de servicio público describimos las posibilidades que nuestro derecho administrativo nos ofrece para, posteriormente, contrastar estos modelos con los efectivamente aplicados. Para ello hemos revisado las diferentes fórmulas aplicadas en las principales ciudades españolas.

One of the sectors hit hard by the outbreak of the coronavirus at the end of 2019 was air transport, which experienced a significant crisis and a drop in traffic in 2020 and 2021. With this context in mind, the aim of this study is to examine the impact of the epidemic on a specific site, Debrecen International Airport, and to identify the changes in the airport's traffic. The results show a significant decrease in passenger traffic both in 2020 and 2021, and a change in the distribution of traffic by type of air transport (scheduled, chartered, and other). With regard to the distribution of passenger traffic by month, the impact of the restrictions in force is mainly noticeable. The importance of each destination also shifted as a result of these changes. The significance of the longest-established destinations (London/Luton and Eindhoven) was maintained, while flights to summer holiday resorts (Larnaca, Palma de Mallorca) became very popular in 2021. Flight occupancy rates varied widely both by month and by destination, but was generally lower than in 2019.

With the aid of recent technological advancements, seamless integration of shared mobility services and public transit may offer efficient and affordable connectivity to the transit stations in urban settings, thereby enhancing residents' mobility. A previous research mainly focused on car-sharing services as a self-standing mode of transportation. However, due to rapid urbanization acceleration and regions' extension, commuters often combine the fixed-route/fixed schedules public transportation and carsharing service in one journey. To this end, we study a one-way, station-based electric car-sharing service interaction with public transportation. We propose an integrated route choice and EV assignment model to address the potential of car-sharing services as a feeder to the public transit network. e integrated model consists of two components, operations of the car-sharing service and the commuter's route choice and the associated mode choice. e service provider decides on the resource levels, allocations, and relocation strategy in the first component. In the second component, the travel options for the commuters are modeled. e two-component model was simulated in an agent-based simulation based on a case study from the state of Qatar. We further extend the integrated model to include the carpooling option, in which multiple passengers sharing the same route can share the same vehicle. Extensive simulation analyses show that the integration can considerably enhance urban mobility and increase public transportation accessibility through enhanced first and last miles linkages. Moreover, the influence of transportation supply and spatial characteristics on the individual mode choice was estimated. Results indicate that public transit ridership can increase up to 17%. Moreover, adding the carpooling option can significantly decrease the number of relocations operations at a minimal impact on the commuters' trip performance.

This paper analyzes the cost structure of the Swiss urban public transport sector in order to assess scale and scope economies. A multi-output cost function has been estimated for a panel data set of companies operating trolley-bus, motor-bus and tramway systems. The results suggest increasing returns to scale and economies of scope. This analysis has important policy implications in view of the ongoing reforms in several European countries in which competitive tendering is occasionally used to assign the provision of transport services to unbundled franchised monopolies. The significant scope economies provide some evidence in favor of integrated multi-mode operation as opposed to unbundling.

The public transport system of Santiago de Chile presents several deficiencies in terms of accessibility, especially for people with reduced mobility. However, there is no official guideline or prioritization on how to value these improvements on accessibility, making them a costly expense. This paper values accessibility elements in the urban bus system of public transport in Santiago, Chile, through a stated preference experiment. The attributes included in this experiment are: audiovisual information at bus stops, elevation of stops, buses' access ramps, and time of travel. Based on the data collected from the survey, discrete choice models were estimated to obtain the preferences and valuations of individuals for the elements, with a focus on people with reduced mobility. The results show that individuals with reduced mobility value at least twice the accessibility elements than people without reduced mobility.

2024, World Development Perspectives

Many Indian cities are investing in mass transit projects, such as metro rail networks and bus rapid transit (BRT) systems. In addition to mass transit, the development of an effective public transport network also requires the integration of many thousands of local paratransit operators who provide mobility in areas poorly served by the formal public transport system. In New Delhi battery rickshaws have emerged as one such mode in a dramatic way. In 2010, there were no battery rickshaws, but by 2013, there were an estimated 100,000, operated primarily by individual owner-drivers. This proliferation came despite a complete absence of state involvement: battery-rickshaws operated outside the ambit of the regulation, and in defiance of the city's very highly regulated paratransit market. This paper aims to identify the causal factors behind their emergence, spread and eventual formalisation based on fieldwork carried out in New Delhi in 2014-2015. In doing this it makes arguments about their role and political-economy. It uses survey data to show that battery-rickshaws provide "last mile connectivity" to metro stations, a market in which they are out-competing all other modes including low-cost cyclerickshaws. It argues that the demographic advantages enjoyed by battery-rickshaw operators enabled their constitution as a voting bloc in the Delhi Legislative election in 2014, which effectively guaranteed formalisation on concessionary terms. Regulators must consider the role of paratransit as an employer, rather than focusing on legality, as they seek to meet the rising demand for last-mile services in urban areas of the developing world.

Poor access (last-mile connectivity) to metro rail systems in India has contributed to lower-than-planned ridership, causing the underutilization of over US$25 billion in investments in the sector. There is little understanding of what metro commuters seek from their last-mile commute. This paper draws from a three-city survey of 7,200 metro commuters to understand current metro user demographics and last-mile choices and preferences. Our data shows that Indian metro systems attract young, middle-income commuters. Indian metro commuters are highly sensitive to last-mile wait times and costs. The paper suggests that robust, periodic data collection and analysis are required to plan viable commuter-centric last-mile services.

Background: Prambanan Ekspres Railway is known as one of the commuting modes in Yogyakarta, Indonesia. Sufficient egress modes do not support this railway. Due to lack of urban mass transit facilities, the commuters independently utilize a reliable mode for their mobility, for instance by owning a motorcycle and using overnight parking service facility in their non-home-station. Objective: This paper aims to understand the commuters’ behavior on their egress trip when they decide to use the train as their main mode. Methods: A direct interview survey on the train was conducted during peak hours from Monday to Friday. By implementing stated preference survey, a logit model was used to analyze mode choice decision from the railway station to activity end destination. Results: The results indicate that walking distance to the parking area and bus-waiting time have a more significant impact compared to the walking distance to bus stop and in-bus travel time. Furthermore, the high cost o...

The railways are a priority transport mode for the European Union given their safety record and environmental sustainability. Therefore it is important to have quantitative models available which allow passenger demand for rail travel to be simulated for planning purposes and to evaluate different policies. The aim of this article is to specify and estimate trip distribution models between railway stations by considering the most influential demand variables. Two types of models were estimated: Poisson regression and gravity. The input data were the ticket sales on a regional line in Cantabria (Spain) which were provided by the Spanish railway infrastructure administrator (ADIF – RAM). The models have also considered the possible existence of spatial effects between train stations. The results show that the models have a good fit to the available data, especial the gravity models constrained by origins and destinations. Furthermore, the gravity models which considered the existence ...

Whereas in some cities ropeways already belong to the transit system, in Germany they are better known from skiing in the alps or as tourist attractions that were implemented in relation to expositions as in Koblenz or Berlin. Nonetheless, a ropeway system has several advantages, which make it an interesting alternative in urban public transportation. In this paper, we investigate the varying attitude of residents and commuters towards a ropeway system and its potential on a route in the north of Munich. To get an impression of their opinion, we conducted an online survey focusing on route choice depending on transit mode and travel times. In general, the respondents had a positive attitude towards this novel option and rate it with similar attractiveness to subway. To investigate the demand for the ropeway, the results of the survey were used to add a new transportation mode in the VISUM model for transit in Munich.

Transport is the most important parameter of rural, peri urban and urban land use change. Paratransit modes are mostly used for trips with shorter journey length, link trips and marketing and educational trips. They are also essential to feed the main roads with the feeder roads. At the beginning Kolkata was designed on pedestrian movement and mass transit in the form of tram. That time cycle rickshaw and hand puller rickshaw were the principle mode of transport to connect main road. Later on with development of new technologies the use of environment friendly rickshaw got reduced and promotion of taxi and auto rickshaw began. Present study will focuses on the spatial expansion of Kolkata city toward south along the auto rickshaw routes and an emphasis will be given to find out their reciprocal relationship. This study reveals that auto rickshaw is both the boon and bane of Kolkata city, as it can move through both the arterial and major roads. But in congested areas this has create...

One of the key challenges on the road to sustainable mobility is the development of low/zero emission urban public transport (UPT). This is crucial in order to meet environmental requirements aiming at reducing greenhouse gas (GHG) emission. In some countries (e.g., Poland) reduction of air pollution is also an important reason behind the implementation of low/zero emission UPT. The aim of this study is to investigate the factors and mechanisms influencing the development of modern electromobility in Polish UPT. We have examined all 242 UPT systems in the country in terms of the characteristics of the relevant urban municipalities, such as size, economic prosperity, level of human and social capital, development paths of urban public transport in the long term as well as the institutional context and proximity and connections to other cities with experience in electromobility. Classification and statistical methods are used based on a variety of approaches, as assigning a score to v...

This study analyzes the accessibility of commuters to bus stops within Kaduna metropolis. Bus stop accessibility is a vital component of a successful transportation system. The research evaluates accessibility to bus stops within the Kaduna metropolis. The source of data for the study includes a structured questionnaire, satellite imagery, and a Global
Navigation Satellite System. The study took a socio-demographic dimension and obtained data from the structured questionnaire; the data included variables such as; walking distance, passenger fare, waiting time, bus availability, and means of accessing bus stops. Purposive sampling was used to select 12 bus stops with the highest activity within the study area. 400 bus commuters were purposively interviewed, those waiting to board or alight buses at the bus stop using a schedule. For a presentation of the summarized data, descriptive and inferential statistics were used. A
regression model was also used to determine which of the variables on the questionnaire are significant in showing problems of accessibility. This revealed that trip fare, place of access, waiting time, and walking distance are positively significant problems of accessibility. The study concluded that using socio-demographic characteristics to determine accessibility is quite essential as not only a spatial analysis is used to determine accessibility.

The phenomenon of urban sprawl has been a huge issue since the beginning of 20 th century and is characterized by rapid and unbalanced settlement development, with transportation network, particularly in the suburban areas. Academic researches have explained the linkage strategy between transportation network and urban planning. However, insufficient empirical verification has been carried out to reduce this phenomenon by using the integrated approach of space-transport development. This paper focuses on analyzing the improvement of public transport (PT)system strategies. The research is analyzed by using microscopic data and by distributing questionnaires in order to assess the impact of settlement development in the suburbs. The impact of PT improvement has an effect on the settlement. The conclusions reveal that the requirement to improve PT-system should be facilitated together with the expanding settlement development. The combination of PT-system has to be involved to reduce 35% in travel time and to increase doubling of the use of public transport.

Commuters' travel pattern to their desired destination mainly depends on the availability of public transport facilities. Especially in developing countries, various infrastructure planning projects are being implemented to meet public transport commuters' needs. Public transportation facility is witnessing transformational changes globally and locally. This study aims to identify the commuter's preferences of feeder modes for their firstmile and last-mile connectivity. The study was carried out in Kochi city focusing on the metro corridor. The data were collected using a stated cum revealed preference questionnaire survey from various locations, including various metro stations and public transport station points in Kochi city. Collected data were initially cleaned by removing the non-logical data and missing information data from the data set. The results obtained from this research work are case specific. The findings from the study show that the majority of commuters prefer autos and e-bikes as their feeder mode option for first-mile and lastmile connectivity. The least preference is given for the bicycle mode of feeder service. The findings from this research will aid transportation planners in providing appropriate and efficient feeder services to improve the public transportation system's first and last-mile connectivity.

People face different barriers when choosing to commute by bike. The predominance of these barriers in users' perception could explain the low cyclability rates present in many cities. An investigation of cyclists' perceptions is developed using the data set obtained through a survey made to individuals from Quito, Ecuador. This study is aimed to evaluate the perception of a group of individuals about barriers to bike use, in particular, assesses how perception varies according to the available information and the different profiles. Using ordered probit models, the study compares the overall evaluation of bike acceptance before and after making individuals reflect on the importance of certain variables (e. g. lack of bike infrastructure, city temperatures, etc.). The main results show that to improve bike use acceptance, enhancing multimodality or providing facilities like electric bikes must be considered. The results also demonstrated a high heterogeneity of individuals' perceptions caused by their socio-demographic characteristics and the environmental context.

La principal herramienta en la modelación de la demanda de transporte durante muchos años ha sido el Logit Multinomial (MNL), pero sus limitaciones, fundamentalmente el supuesto de independencia de alternativas irrelevantes, han motivado diferentes mejoras, destacando entre ellas el Logit Mixto (ML). El ML permite mayor flexibilidad en las preferencias individuales, aunque no por ello ha colmado las expectativas de los modeladores, ya que el objetivo es representar la realidad de la forma más veraz posible. De este modo, se ha planteado la inclusión de elementos subjetivos, a través de modelos de utilidad híbridos que consideran atributos tangibles, fácilmente identificables para cada alternativa, así como elementos intangibles asociados a las percepciones y actitudes de los individuos, expresados a través de variables latentes. El principal objetivo de este trabajo es identificar las variables latentes relevantes en la modelación de la elección modal en el ámbito urbano, así como l...

School is one system activities that generates movement and will attract movement from settlements as student residence. The objectives of this research are, to analyze the attraction of school students, to analyze the factors that influence the selection of public transport modes towards schools, analyzing the selection of student public transport modes and to formulate the direction for effective plan for developing school transportation in Bogor City. The methods used are flow mapping method, binary logistic regression method, proximity analysis, and descriptive analysis. The results show that the attraction of elementary students is sufficiently appropriate because they followed the zoning regulation which can be seen from the majority of students come from designated zone, while the result of junior high school student’s attraction show relatively insufficient because the majority of the students come from outside the designated zones. The estimation results of factors that sig...

This paper examines the impact of the perception of bicycle infrastructure on the choice of the bicycle as a feeder mode to access train stations in the Netherlands. The latent factors act in addition to traditional travel time and cost variables, describing the quality of cycling infrastructure at and around railway stations. The analysis is based on a large scale revealed and stated preference survey in the wider metropolitan area of The Hague and Rotterdam (n ¼ 1524). Hybrid choice models for access feeder mode choice were estimated, where the attitude toward cycling to affected the users' perception of the cycling infrastructure, which in turn affected the utility of cycling. The results show that both the quality of cycling infrastructure and latent factors, describing the perceived quality of cycling infrastructure, station connectivity and the general attitude toward cycling, have a significant impact on cycling to the station. The effect of the travel time and cost characteristics on access mode choice significantly changes depending on the perception of the quality of the infrastructure, as well as the attitude toward cycling and frequency of train use. Bicycle parking cost and distance to the platform is the most critical observed factor influencing bicycle access choice to the train stations.

Promoting mobility by public transport, rather than individual automobiles, is a worldwide accepted and promoted sustainable solution. Traditionally, cycle-rickshaws have been the backbone of localised transportation in cities of India, thus a key component of ’Last Mile Connectivity’ (LMC) in the urban transport sector. However, in the last few years, there has been an attempt to replace cycle rickshaws with battery-operated ’e-rickshaws’ to make cities smarter. This paper examines the feasibility and consequences of such change in Ranchi, the capital city of Jharkhand state in India, its impact on traditional cycle rickshaw pullers; and how they fit in the overall urban transport sector. This paper presents Passengers’ and Drivers’ overall experience of E-Rickshaws and Cycle Rickshaws in promoting last-mile connectivity. Data collected through in-depth interviews with twenty e-rickshaw drivers, twenty rickshaw pullers, and twenty passengers in Ranchi highlights the user experiences of erickshaw and advantages, disadvantages, as well as the effectiveness of e-rickshaw on the streets. The study shows that E-rickshaws and cycle rickshaws may remain a viable Last Mile Connectivity in the urban transport sector.
