Time use models have been used to estimate the value of leisure - one of the components of the value of travel time savings - usually accepting that sleep duration is an exogenous variable. In this paper, we depart from this belief by considering time asleep as an endogenous decision framed by many elements well documented in the literature which we review using a three-discipline perspective: Social

Despite increasing interests in travel-related subjective well-being in transport research, few studies have explored the effects of residential environment on travel satisfaction, especially how travel satisfaction may change after residential relocation. This study investigates whether and how residential relocation leads to changes in travel satisfaction. Using a two-wave questionnaire survey conducted

The introduction of High-Speed Railways (HSRs) redefines the connections between main territorial hubs, by reducing the travel times and guaranteeing better accessibility. Such infrastructures bring advantages in terms of travel performances, but have also some drawbacks especially for those, generally, mid-size cities that are downgraded. This paper introduces the Spatial and Social Equity Railway

Globally, there are a wide variety of policies in place that could help contribute to deep greenhouse gas (GHG) emissions reductions in the light-duty vehicle sector. Most regions are impacted by a mix of such policies. However, the transportation literature has devoted little attention to policy mixes, especially in the light-duty vehicles sector, so here we review and draw insights from the broader

The mode share of app-based ride-hailing services has been growing steadily in recent years and this trend is expected to continue. Ride-hailing services generate two types of trips – passenger hauling trips and deadheading trips. Passenger hauling trips are the trips made while transporting passengers between places. Virtually all other trips made by a ride-hailing vehicle when there are no passengers

Improving bus stops by providing shelters, seating, signage, and sidewalks is relatively inexpensive and popular among riders and local officials. Making such improvements, however, is not often a priority for U.S. transit providers because of competing demands for capital funds and a perception that amenities are not tied to measurable increases in system effectiveness or efficiency. This study analyzes

Understanding the impact of weather on travel behavior provides insight into building a reliable and resilient transport system. This study uses a survey on residents and subway ridership data from 2014 to 2018 in Beijing to explore the relationship between weather and travel behavior. The results indicate that extreme weather events can affect recreational travel greatly, reduce travel demand, and

With new rail lines, residents can enjoy higher accessibility and more activity opportunities. However, better access to public transport can potentially increase land prices in catchment areas. In this research, we aim to investigate whether this capitalisation effect goes beyond the conventional catchment area and how such an effect varies across different regions. In a departure from previous studies

Public transport is being promoted worldwide to help resolve the environmental and congestion problems besetting cities. Travel comfort is increasingly seen as crucial to effecting the switch from private motorized modes to public transit. The purpose of this study is to measure the physical and human factors impacting travel comfort on mass urban rail transport. Randomly selected passengers (n = 368)

Buses operating in mixed traffic experience problems with delay and travel time variability in peak periods. Numerous transit priority measures are found in the literature but most rely on separating buses from other vehicles. Complete separation such as dedicated bus lanes might underutilize the system capacity when the frequency of buses is not high. We propose a “dynamic bus lane policy”, where

After fifteen years of railway concessions in Brazil, the rail freight sector became responsible for over 26% of the total transported volume in the country, an increase of 20% during this period. This Brazilian experience led a recovery in productivity and investment levels, with an improvement in service quality and modernization of the sector. Nevertheless, the rail price control mechanisms were

Port competition has changed from the competition between two single ports to that between two transport chains. The overlapping hinterland between two ports grows with the constant development of transport chains. A variety of subsidies offered to shippers by ports were put into practice for larger hinterland freight volume to improve port competitiveness. A study of the effects of shipper subsidies

Although previous studies have explored predictors of Congestion Charging (CC) acceptability and acceptance, there is no study investigating the rule-breaking behaviour towards a CC scheme. The current study thus examined the effects of a wide range of attitudinal factors as well as demographic, socioeconomic, built environment and travel-related characteristics on rule-breaking/following behaviour

Transport policy makers are increasingly perplexed by the pace of change in their sector and by the increasing influence of external actors. This leads to a variety of responses, including “business as usual”, technological optimism, technological fatalism and technological ignorance. To explore this perplexity and its justification, we examine four areas of technological advance relevant to transport:

As a non-ownership business mode, a car-sharing service system has received an extensive popularization recently. Many related studies based on the theoretical and questionnaire analyses have confirmed the existence of differences in usage patterns between car-sharing users and private users. Nowadays, usage data provides a new way to analyze and understand the usage pattern of vehicles, which can

Although Autonomous Vehicles (AVs) will enhance mobility and safety, their impact on congestion is not clear yet. AVs may increase roadway capacity due to their connectivity features. The capacity enhancement highly depends on the AV proportion in traffic. This study models user equilibrium traffic assignment when the link capacity is a function of AV proportion of traffic. The mixed traffic flow of

Over the years, passenger incentives have increasingly been used in Swedish public bus transport to increase ridership by introducing passenger incentive contracts. In 2015, half of all active contracts were of this type. In those contracts, operator revenue comprises production-related revenue and a per-passenger–based incentive payment. Using rich passenger data, this paper analyses whether the ridership

Free-floating bikesharing (FFBS) is a fairly new mobility service. It spread rapidly throughout Europe’s major urban areas in 2017; a development accompanied by a variety of problems that soon culminated in a retreat of providers from most cities. The main characteristic of FFBS is the absence of fixed docking stations; instead, users can borrow and leave the bikes wherever they want as long as they

Subsidies are used to promote pure electric vehicle adoption. Whether cost factors are the dominant factors influencing households’ purchase intentions under subsidy contexts is unknown, which is meaningful as subsidies decrease. To explore whether cost factors influence Chinese urban households’ purchase intentions for electric vehicles under subsidy contexts, we conducted a questionnaire survey among

A novel approach to dynamic switching service design based on a new queuing approximation formulation is introduced to systematically control conventional buses and enable provision of flexible on-demand mobility services. This new approach guides smart vehicles in a service area that needs last mile transit services via either traditional buses, which provide fixed-route services, or flexible-route

City-level circuity factors have been introduced to quantify and compare the directness of vehicular travel across different cities. While these city-level factors help to improve the quality of distance approximation functions for city-wide vehicle movements, more granular factors are needed to obtain accurate shortest path distance approximations for last-mile transportation systems that are typically

Considering the connectivity characteristics of the logistics infrastructure between adjacent areas, this paper examines the possibility of spatial spillover effects of logistics infrastructure in Chinese regions by applying a spatial Durbin model for the time period 2003–2017 and two sub-periods, 2003–2009 and 2010–2017. At the national level, the results indicate that positive spillover exists in

Since the Belt and Road (B&R) Initiative was launched in 2013, China’s investment in ports across the globe has promoted maritime connectivity, driven performance in shipping, and strengthened its commercial maritime power. With the objective of quantitatively evaluating a country’s commercial maritime power, we develop an evaluation system based on the literature and the analytic hierarchy process

This paper presents an algorithm to find multimodal shortest hyperpaths in a transport system where transit arrival is random (i.e. random-arrival transit system), while real-time information on vehicle arrivals is only available for some lines and modes. When the algorithm is queried, there is a short horizon where real-time information is accurate, and past this the most reliable information for

Bicycle is a sustainable low-carbon transport mode. However, insufficient or unplanned infrastructure leads to decrease in the share of bicycle in many cities of developing nations. In order to increase the bicycle share and to provide safer, faster and more direct routes, a bicycle superhighway is proposed for urban areas. This study identifies the potential of increase in the bicycle share. For maximum

Unconventional modes of transport (UCMs) play a substantial role in many developing cities in meeting the mobility demand in spite of having negative image in the eyes of the authorities. This manuscript outlines a conjoint framework where various factors affecting sustainability and competitiveness of UCMs are identified through observation study and organized using PESTLE qualitative framework. Afterwards

On the basis of 143 responses from experts and stakeholders from Germany, Austria, Spain, the Netherlands and the UK, we assess the perceived impact of a range of incentives for the uptake of electric vehicles (EVs). We find that the incentive that most respondents consider to have a positive impact is the development of charging infrastructure, with 75% stating so. This is followed by purchase subsidies

The toll design problem (TDP) provides a quantitative approach to the design of road pricing schemes. Its practical use, however, can be computationally challenging if the formulated TDP requires time-consuming computer models to evaluate candidate designs, especially if such designs must account for multiple objectives. For TDPs to be of practical relevance to the real-world planning of sustainable

The classification of the urban traffic state and its application is an important part of intelligent transportation systems (ITS), which can not only help traffic managers grasp the traffic operation situation and analyze congestion, but also provide travelers with more traffic information and help them avoid congestion. Thus, an accurate traffic state classification method would be very practical

New retail trends show the increasing importance of providing cost efficient deliveries in cities, where congestion and compliance with driving hours regulations should be incorporated into routing software. This paper introduces a large neighbourhood search algorithm that substantially improves the benchmark solutions (in terms of the number of vehicles required, travel distance and duty time) for

Crowding levels are very relevant for the analysis and evaluation of the performance of public transport as they strongly affect the level of service and the overall perceived quality of the system. However, crowding is not an easy variable to measure and, hence, demand models often tend to ignore or use abstract proxies for it. In this paper, we assess the Multiple Indicator Solution (MIS) method

The second in a series of two, this paper conducts a review of the public-sector initiatives that could be used to improve freight activity in metropolitan areas, collects data about the initiatives that have been implemented and their performance, and produces a ranking of suggested initiatives. The review of public-sector initiatives is based on a comprehensive analysis of their performance, which

In this paper, we propose a bi-objective bi-level programming model to balance economic growth and environmental management, which orients sustainable transport development by combining a tradable credit scheme (TCS) and a link capacity improvement measure. At the upper level, the decision maker aims to both maximize the economic benefit and minimize the total amount of traffic emissions by the optimal

Growing interest in zero emission transport modes, such as cycling, is currently generating motivation to construct new cycle paths. However, transportation planners and managers cannot always rely on practical methods for allocating the resources (often limited) needed for inventories and assessing cycling infrastructures. The aim of this study is to develop a method for classifying cycle paths in

The first in a series of two, this paper conducts a review of the public-sector initiatives that could be used to improve freight activity in metropolitan areas; collects data about initiatives that have been implemented and their performance; and produces a ranking of suggested initiatives. The review of public-sector initiatives is based on a comprehensive analysis of their performance, which cataloged

Background Planners and politicians in many countries seek to increase the proportion of trips made by cycling. However, this is often challenging. In England, a national target to double cycling by 2025 is likely to be missed: between 2001 and 2011 the proportion of commutes made by cycling barely grew. One important contributory factor is continued low investment in cycling infrastructure, by comparison

As standards for vehicle greenhouse gas emissions and fuel economy have become more stringent, concerns have arisen that the incorporation of fuel-saving technologies may entail tradeoffs with other vehicle attributes important to consumers such as acceleration performance. Assessing the effects of these tradeoffs on consumer welfare requires estimates of both the degree of the tradeoffs, and consumer

Cycling in urban environments provides many benefits to people. However, planning of cycling infrastructures in large cities faces numerous challenges and requires better understanding of both the factors enabling cycling as well as barriers to it, determined by particular local context. While there is a growing body of research that tackle the bike transport related questions in Western Europe and

We analyse a new data set to examine how congestion charging policies affect an individual's investment social capital. We exploit a (quasi-) natural experiment - the implementation of the Western Extension Zone (WEZ) to the London Congestion Charging zone in 2007. We measure investment in social capital by using the frequency of visits to friends and family before and after the implementation of the

Heavy dependency on car use leads to traffic congestion, pollution, and physical inactivity, which impose high direct and indirect costs on society. Promoting walking and cycling has been recognised as one of the means of mitigating such negative effects. Various approaches have been taken to enhance walking and cycling levels and to reduce the use of automobiles. This paper examines the effectiveness

Understanding the contextual factors associated with why adults walk is important for those interested in increasing walking as a mode of transportation and leisure. This paper investigates the relationships between neighborhood-level sociodemographic context, individual level sociodemographic characteristics and walking for leisure and transport. Data from two community-based studies of adults (n=550)
