Background Variable message signs (VMS) have been widely applied to alleviate traffic congestion by providing spatiotemporal information related to traffic and network conditions to drivers. There is a debate on whether the VMS information would lead to the less-alleviation of congestion or congestion transfer to the adjacent roads in the different traffic congestion situations due to the inappropriate

The effects of social interactions on individual behaviour have been observed in many social phenomena, including travel-related behaviour involving direct or indirect contact with other agents. However, most formulations of urban transport policy assume that individual behaviour is independent of each other, which likely results in policy evaluation bias. Therefore, this study aimed at urban parking

Transport poverty is a growing concern in many developed countries. However, research on the determinants of transport poverty is relatively scant. We contribute to the debate on the determinants of transport poverty by presenting the first study to empirically examine the effects of ethnic diversity on transport poverty. Using 12 waves of longitudinal data from the Household, Income and Labour Dynamics

This study proposes an urban Bikeability Index (BI) to assess and prioritise bicycle infrastructure investments, and in turn, improve accessibility for cyclists. The contribution of this paper is twofold. First, we construct a BI that addresses particularities of the roads in cities of the Global South and considers the preferences, perceptions and socioeconomic characteristics by type of cyclist.

Denmark is one of the world-leading countries in terms of bicycle infrastructure and has a relatively good public transport system. Yet, a large share of commuters in the Greater Copenhagen Area still uses the car on a regular or semi-regular basis, causing severe problems of congestion and pollution. This article seeks to understand to what extent individuals’ perceived mobility necessities (PMN)

Government sectors often provide guarantees in build-operate-transfer (BOT) roads to attract private investments. Since a fiscal burden would be incurred from the contingent liability of issuing a guarantee, charging a fee for the guarantee is considered an effective remedy for management of contingent liabilities in practice. This study incorporates the charge mechanism for minimum traffic guarantee

E-scooters are rapidly changing transportation in US cities and university campuses. Hailed as a convenient, inexpensive solution for “last mile” and other short trips, e-scooters are available in over 100 US cities and were used for nearly forty million trips in 2018. Yet relatively little is known about e-scooter use, including who uses them, for which types of trips, and the perceived benefits and

This study examines planners’ views of transit sexual assault in two transit systems where sexual assault is widespread, but little action has been taken: TransMilenio Bus Rapid Transit (BRT) system in Bogotá and Soacha, Colombia and informal transit in El Alto, Bolivia. In both cases, many planners lack information about transit sexual assault in their city, and the agencies do not systematically

China's Belt and Road Initiative (BRI) has attracted much attention in the field of transportation research. With a primary goal to improve regional and global connectivity, the initiative proposes a massive development programme of transportation infrastructure (TI) linking China with the rest of the world. While it creates a tremendous development opportunity, the unprecedented scale of TI construction

Highly automated vehicles (AV) are in the early stages of deployment and are likely to have significant impacts on the United States transportation system. In particular, a broad deployment of shared, on-demand AVs might significantly impact vehicle ownership and transportation energy consumption; projecting these impacts is essential for climate, infrastructure, and policy planning. However, it seems

The co-existence of traditional docked bike-sharing and emerging dockless systems presents new opportunities for sustainable transportation in cities all over the world, both serving door to door trips and accessing/egressing to/from public transport systems. However, most of the previous studies have separately examined the travel patterns of docked and dockless bike-sharing schemes, whereas the difference

Drawing upon Flyvbjerg's (1998) insight that planning is defined more by the political than the rational, we examine the experience of parking reform, as attempted by municipal officials, in Vancouver, British Columbia. The literature offers a broad consensus that minimum parking requirements represent a misguided and inefficient policy producing excess parking in the wrong places and reduced housing

While most consumers agree that adopting more sustainable mobility behaviors should be a priority, this attitude often fails to translate into actual behavior. We argue that this is because sustainable mobility products do not sufficiently satisfy consumer mobility motives. To investigate this issue from a multi-modal perspective, we first synthesized previous research into a general measure of superordinate

This study aims at quantifying preference heterogeneity in transit service desired quality to better-informing service quality improvements. The analysis is performed using a validated dataset elicited from 906 respondents through an online survey. An unlabelled Stated Preference (SP) experiment was utilized in a Latent class Choice Model (LCM), and an Error Components interaction model. The results

China Railway Express (CR express) refers to the regular container trains transporting between China and European countries under the Belt and Road Initiative (BRI). This paper aims to conduct the systematic and in-depth research on the importance ranking of logistics nodes across the complex CR express network from China’s national plan of the BRI perspective, with consideration of the connectivity

Although the last decades have seen an advance in equality and empowerment for women, there are still numerous challenges to be addressed. Among them, and particularly pressing in cities, are issues of gender-based violence, including sexual harassment in public spaces. Despite the numerous effects that street harassment has on women, and the high incidence of it in different countries, this issue

Peak-avoidance has been suggested as a strategy to ease congestion and improve the travel experience in the road traffic system. However, commuters’ trade-offs when choosing whether to avoid the peak in the context of subway use have not yet been explored. In highly concentrated megacities, high demand during peak hours in the subway leads to long queues waiting to enter stations or platforms, as well

Detailed ridership analytics requires refined data on transit ridership to understand factors affecting ridership (at the stop and/or route-level). However, detailed data for stop-based boarding and alighting information are not readily available for the entire bus system. Transit agencies usually resort to compiling ridership data on a sample of buses operating on the various routes. We propose an

In this paper, we investigate the economic effects of deregulation in Japan’s intercity coach industry. Specifically, we examine the intensity of competition in the industry using a unique dataset, to evaluate the economic effects of two major deregulations in 2002 and 2013. The absence of organized data means there is no previous research that quantitatively evaluates the deregulations. We collect

This study proposes a series of statistical and regression approaches to investigate city-cluster transport connectivity patterns. Three major city clusters in China are selected for this study, namely, the Beijing-Tianjin-Hebei (BTH), the Yangtze River Delta (YRD), and the Pearl River Delta (PRD) economic zones. Our analyses examine three aspects of city-cluster connectivity patterns: (i) connectivity

Although several papers have shown that bike ridership is affected by actual weather conditions, this is the first study to comprehensively investigate the impact of forecasted weather conditions on bike ridership. The results show that both actual and forecasted weather conditions can be used as useful explanatory variables for predicting bicycle usage. Even incorrect weather forecasts can impact

A necessary condition for the effective integration of automated vehicles in our daily lives is their acceptance by passengers inside and pedestrians and cyclists outside the automated vehicle. 119 respondents experienced an automated shuttle ride with a ‘hidden steward on board’ in a mixed traffic environment in Berlin-Schöneberg. A mixed-method approach was applied gathering qualitative interview

In this review paper, we reconceptualise the relationships between travel-related attitudes and behaviours using (and considering the applicability of) Festinger’s cognitive dissonance theory. According to this psychological theory – developed in the 1950s and widely used ever since − a dissonance between attitudes and behaviour can result in feelings of discomfort, which people will try to reduce

The deployment of autonomous buses (AB) is expected to have consequences for service design facilitated by its cost function structure. We study the impacts of AB deployment in line-based public transport (PT) systems. In particular, we examine the transition phase where AB is sequentially deployed, involving the selection of lines for which AB will be introduced. To this end, we develop a modeling

The scheduling synchronization problem in this paper is to obtain an optimal schedule by optimizing running time, departure time, dwell time and arrival time of the last train in urban rail transit networks. Operators are often faced with multiple conflicting requirements simultaneously such as high passenger’s service quality and less cost, smooth transfer events and less passenger’s travel time,

Passenger cars account for most road transportation emissions, and almost half of overall transport sector emissions in the EU. Countries in Europe have established policies to achieve emissions reductions in the transport sector by incentivizing the acquisition of fuel-efficient vehicles. In this paper, we perform a pair-wise comparison of common passenger vehicles sold in 2017, which implements newer

This paper investigates two fundamental questions related to the social impact of high-speed rail (HSR): (1) does the development of HSR infrastructure lead to the exclusion of certain social groups? and (2) what factors exclude certain users from using HSR? Based on a comprehensive survey of 4,924 passengers who chose conventional rail services in China, both binary and multinomial logit analyses

A widely used approach to valuing transport infrastructure is to look at its effects on housing prices, in treated vs control regions, before and after it is built. But anticipation effects mean that housing prices may start changing as soon as a project is announced. This creates complications for an analysis of the capitalization effects on prices. A long span of data is potentially required—because

Bike sharing could provide a key role in a transition towards a less car dependent and more sustainable, healthy and socially inclusive urban transport future. This paper investigates two important prerequisites for bike sharing to fulfil these premises: Does it synergise rather than compete with current alternatives to car-based urban mobility; and is it inclusively accessible across population and

The advent of autonomous vehicle technologies and the emergence of new ride-sourcing business models has spurred interest in Automated Mobility-on-Demand (AMOD) as a prospective solution to meet the challenges of urbanization. AMOD has the potential of providing a convenient, reliable and affordable mobility service through more competitive cost structures enabled by autonomy (relative to existing

Public bicycle sharing system (PBSS) has been adopted around the globe to reduce traffic congestion, CO2 emissions and for positive health effects. The first system was initially started in the year 1965 at Amsterdam and now it has been expanded almost in all the continents of the globe. The adoption of this concept was initially seen in developed countries. Now in the past decade various developing

Automated driving technology along with electric propulsion are widely expected to fundamentally change our transport systems. They may not only allow a more productive use of travel time, but will likely trigger completely new business models in the mobility market. A key determinant of the future prospects of both existing and new mobility services will be their production costs. Hence, in this research

Bus Rapid Transit (BRT) has proven to be an effective and affordable transportation option for large-sized cities. In these cities, BRT is usually considered an effective complement or substitute for rail-based systems, playing a key role in complex multimodal networks with several massive transport corridors. More recently, medium-sized cities of less than 200,000 inhabitants have also considering

The value of time (VOT) is a central parameter in freight transportation. However, both its trend and influencing factors remain poorly understood. To reduce potentially diverging influences of different theories and methods used to calculate VOTs in freight transportation, only VOTs obtained from discrete choice models with disaggregated data were studied. Based on statistical analysis and regression

Specialisation is a common strategy followed by ports to face the challenges of globalisation, changes in the naval industry and maritime operations. The main objective of this research is to determine if specialisation and size of ports have an impact on port efficiency. We estimate the efficiency of 27 Spanish ports during the 2001–2011 period using a parametric distance function approach. Our results

Metropolises in emerging markets are facing serious urban transport challenges. Understanding people’s travel preferences is crucial for designing effective sustainable urban policies. Little attention has been paid to studying travel preferences in multimodal transport systems in these markets. This study estimates the travel preferences in the metropolitan area of Beijing, which is notoriously plagued

Origin–destination (OD) matrices are one of the key elements in travel behaviour analysis. For decades, transportation researchers have mostly used data obtained by active solicitation such as surveys to construct these matrices but new data sources like automatic fare collection (AFC) are now available and can be used to measure OD flows. As a result, a more heterogeneous corpus of data sources is

The estimation of the free flow speed (FFS) distribution is important for capacity analysis, determination of the level-of-service, and setting speed limits. Subjective time headway thresholds have been commonly used to identify vehicles travelling under free flow speed conditions i.e., vehicles whose speeds are not influenced by the vehicle in front. Since, the headway a driver operates under the

This research examines whether cities are getting more equally accessible and connected via high-speed rail (HSR) in China over the period from 2010 to 2015. Existing studies mainly use network centralities to describe the spatial pattern of HSR network without measuring the spatial disparity of these centralities, and most of them rely on the infrastructure network and thus fail to incorporate HSR

Car-sharing has experienced a significant boom in recent years, with estimates suggesting that car-sharing programs are now operating in over 30 countries worldwide, serving around five million users. The potential to reduce individual vehicle ownership rates is frequently cited as a motive for promoting car-sharing. While some previous studies have argued that customers are indeed willing to reduce

Due to its importance in integrating facilities and smoothing supply chain, facility location and capacity planning problem (FLCPP) is no doubt a key issue in constructing an efficient logistics and transportation network. One Belt and One Road (OBOR) initiative aims at reconstructing the logistics and transportation network along the trade corridors and improving the trade connectivity among the developing

China’s high-speed railways (HSRs) networks have dramatically expanded since 2008, which is widely believed to have promoted economic growth. This study empirically tests this hypothesis and analyses the impact of HSRs on economic disparity between 2002 and 2016 in China using a spatial econometric model. The results confirm the role of HSRs as a driving force in promoting local economic growth, although

The need to transition towards more sustainable futures is evident. This paper explores the role of social enterprise in urban sustainability transitions. Using the UP Bike Share (UPBS), a university-based bicycle-sharing social enterprise (in Metro Manila, Philippines) as a case study, this paper aims to bring a more explicit social entrepreneurship perspective towards sustainability transitions research

Direct demand models estimated to ticket sales data have for many years provided evidence on how key variables influence rail demand in Great Britain. Nonetheless, there has been relatively little estimation of demand models disaggregated by ticket type which would provide own and cross-price elasticities that can inform the pricing of different ticket products. We here report such enhanced models

Autonomous vehicles (AVs) hold great promise to contribute to global sustainability by expanding access to mobility. The introduction of autonomous buses and shuttles could be a turning point for public mobility in the USA, but how autonomous public transit is perceived remains largely unknown. To fill this gap, this study analyzes the willingness to use autonomous buses and shuttles based on two surveys

Ridesourcing (Uber, Careem, Lyft, …) is emerging as a main player in the transportation industry. However, its relation to mass transit remains ambiguous, with divided opinions on its complementarity or substitutive effect towards high capacity public transportation systems. This study examines the integration of ridesourcing and transit, particularly focusing on modeling the demand for mass transit

This paper assesses the ability of alternative fare system designs to change the modal-share of public transport use, as well as their corresponding impact on company revenues. Specifically, we provide evidence for how switching from flat to distance fares or from integrated to non-integrated tickets affects both the ridership and the financial situation of public transport companies. Secondly, because

This study identifies the relationship between individual's travel and their perceived Quality of Life (QoL). We consider two variables for travel reflecting its objective/quantitative and subjective dimensions. The observed one is a measure based on public transport trip frequency and travel duration obtained from smart card data. The second is the perceived level of Travel Satisfaction which is obtained

Passenger vehicles are a major source of air pollution, exposure to which increases respiratory disease risk, amplifies life-threatening conditions and burdens the public purse. The negative externalities associated with these vehicles rise further when road accidents are considered. Almost all such accidents involving fatalities transpire when private users are in single vehicle incidents or collide

We explore how the hypothetical provision of Wi-Fi on transit affects the willingness of non-transit commuters (solo drivers, ridesharers, and cyclists) in Northern California (N = 1402) to switch from their current mode to public transit with internet access (PTWIA). Beyond the prima facie interpretation of our survey results, they shed light on the heterogeneously-perceived utility of hands-free

Location analysis for a consolidation facility is a multi-criteria challenge, compounded by spatial constraints in real-world scenarios such as those found in inner-city areas. However, most decision support models in location studies of consolidation facilities are limited to numerical computation or multi-criteria analysis while ignoring spatial factors in location selection. This study aims to characterise

The impact of app-based e-hailing or ridesourcing services on various transport metrics is an area of active research, and research so far have focused on the car-based (or four-wheeled vehicle based) services only. In many cities in the developing and emerging countries, motorcycle-based passenger e-hailing services have become very popular in the last few years, but the implications of these have

In 1986 the author wrote a paper about tax compliance that theorized that the output of tax inspectors would be constrained by the rate of evasion of tax payments. That paper was never subsequently cited in the literature on transit fare evasion, which presumed that ticket inspection had a simple unidirectional effect on evasion. This current paper argues that all subsequent models of the economic

As emergencies occur more frequently, such as natural disasters and industrial accidents, evacuation planning attracts more and more attention. Bus is often used to evacuate car-free people due to its large capacity and manageability. To improve the efficiency and practicality of public transport evacuation plans, this paper presents a round-trip bus evacuation model based on unfixed routes with simultaneous

Most extant literature in the transportation industry views innovation adoption as a rational choice process conducted on a cost-benefit calculation basis. This restricts our understanding of innovation decisions made by individuals embedded in a social-economic context. By investigating the underlying social psychology of the innovation adoption in the Chinese container trucking industry, this paper

This paper examines the productivity of Norwegian container seaports and the extent to which the initially less productive seaports are converging/diverging in productivity in relation to the initially more productive seaports. The rationale of the paper is that productivity assessment of Norwegian seaports is scarce in the literature, and studies of convergence/divergence in container seaports are

The European Union coordinates and co-finances supra-national transport infrastructure investments in the Trans-European Transport Network (TEN-T), which consists of road, rail, airport, and port infrastructure. To the best of our knowledge, we are the first to quantify the direct and indirect economic growth effects of newly created TEN-T core corridor roads in Eastern European countries. Both the

High-speed railways are expanding rapidly over the world, providing fast, convenient, and comfortable transport. It is therefore important to ensure that people are not excluded from high-speed railway use due to relatively high ticket prices. We aim to develop a railway timetable according to passenger requirements that explicitly considers social equity by applying variable ticket prices to trains

This paper investigates travel mode and airline choice using stated-preference data. Both air and non-air passengers’ data were collected in Western Australia, which allows easier generalisability of the findings to a wider population. A market segmentation approach, using latent class modelling, was applied to identify passenger segments. The results shown a significant difference between identified
