When benefits of proposed infrastructure investments are forecasted, residential location is usually treated as fixed, since very few operational transport models are able to forecast residential relocation. It has been argued that this may constitute a source of serious error or bias when evaluating and comparing the benefits of proposed infrastru...

Significant efforts to incentivize the uptake of energy efficient vehicles (EEVs) are evident across the globe. Given EEV markets are dynamic, and consumer demand may fluctuate in response to incentives, this may also lead to other market forces influencing prices. An analysis of EEV incentives, therefore, must account for the possible endogeneity...

This case study describes the project Elbilslandet (The Electric Vehicle Country) in Gotland, Sweden, where the island Gotland is made “ready for electric vehicles” by providing a network of charging infrastructure and electric vehicle rental during several summer seasons. The influence of the electric vehicle (EV) rental scheme on the process towa...

The real environmental benefits of a transition towards EVs highly depend on the future EV-users' activity-travel patterns adapted to their new vehicle's capacity. Despite its importance, the impact of this adaptation is largely unknown. In this study, a stated adaptation experiment has been conducted to investigate changes of travel patterns as a...

This paper explores the interactions between travel demand, time allocation and mode choice in different seasons by jointly modeling the work and/or study, routine and leisure activity-travel engagements of 67 individuals in Stockholm, Sweden. A longitudinal panel two-week travel diary data collected in four consecutive waves over a span of seven m...

This paper describes and evaluates a stated adaptation instrument to investigate the effects of a transition towards electric vehicles on travel behaviour. The respondents were equipped with an “imaginary” electric vehicle with a specific range and were asked whether they wanted to make changes in an activity-travel schedule they had previously reg...

The city of Curitiba in southern Brazil is considered to be the cradle of the Bus Rapid Transit (BRT) system. Curitiba has a population of around 1.9 million people and has a higher development index than Brazil in general. A master plan approved in the middle of the 1960's has guided the development of the city in a Transit Oriented Development (T...

A large scale deployment of electric vehicles (EVs) is likely to contribute to a more sustainable transport system. However, charging EVs will increase the load on the electricity network. The maximum load may be minimized by coordinating the timing of charging activities, in order to spread electricity demand more equally over the course of a day....

Electric vehicles (EVs) show promise for improving the environmental sustainability of the transport system since, as opposed to conventional vehicles, they have no tailpipe exhaust gas emissions. The use of EVs can also decrease the amount of greenhouse gas emissions, especially if the electricity has been generated with renewable energy sources....

This paper studies electric vehicle (EV) adoption in Greater Stockholm in Sweden using the Transtheoretical Model of Change (TTM) and the Protection Motivation Theory as a framework and considers socio-cognitive, behavioural and socio-economic attributes that may influence the process towards electric vehicle use. TTM considers behavioural change a...

Off-peak-hour delivery programs are a promising but challenging concept for promoting sustainable urban logistics. Stockholm, Sweden, initialized a nighttime freight deliveries program in 2014, aimed at a more efficient and environmentally friendly delivery system within the central area of the city. The policy of shifting freight deliveries from d...

Using multi-day, multi-period travel diaries data of 56 days (four waves of two-week diaries) for 67 individuals in Stockholm, this study aims to examine the effects of out-of-home and in-home constraints (e.g. teleworking, studying at home, doing the laundry, cleaning and taking care of other household member[s]) on individuals’ day-to-day leisure...

In order to increase the attractiveness of electric vehicles (EVs), packages of policy incentives are provided in many countries. However, it is still unclear how effective different policy incentives are. Also, it is questionable that they have the same impact on different groups of people. In this study, based on a stated-choice experiment, the e...

This paper analyzes the efficiency and political acceptability of road pricing and infrastructure policies targeted at relieving urban congestion. It combines a stylized transport model of an urban road network with a model of the political process that incorporates interactions between voters, citizen interest groups and politicians to explore the...

Using a four-wave panel survey of individuals’ trips and psychological attributes collected among residents along a new tram line extension in the city of Stockholm, Sweden, this study aims to investigate factors that determine the individuals’ learning and decision-making processes in using a new transport option. This includes investigating which...

Given the shift toward energy efficient vehicles (EEVs) in recent years, it is important that the effects of this transition are properly examined. This paper investigates some of these effects by analyzing annual kilometers traveled (AKT) of private vehicle owners in Stockholm in 2008. The difference in emissions associated with EEV adoption is es...

As governments seek to transition to more efficient vehicle fleets, one strategy has been to incentivize ‘green’ vehicle choice by exempting some of these vehicles from road user charges. As an example, to stimulate sales of energy efficient vehicles (EEVs) in Sweden, some of these automobiles were exempted from Stockholm’s congestion tax. In this...

Urban congestion causes travel times to exhibit considerable variability, which leads to coordination problems when people have to meet. We analyze a game for the timing of a meeting between two players who must each complete a trip of random duration to reach the meeting, which does not begin until both are present. Players prefer to depart later...

In order to build competence for sustainability analysis and assessment of urban systems, it is seen as essential to build on models representing urban form, landuse and transportation, urban metabolism, as well as ecological processes. This type of analysis of interacting sub-systems requires an advanced model integration platform, yet open for le...

The equity effects of congestion pricing have come into focus as a potential hindrance to its acceptability in implementation around the world. Both theoretical arguments and empirical evidence about how the burden of the toll should fall on demographic groups have been mixed, depending on a variety of contextual factors such as automobile access,...

The standard method to estimate valuations of travel time variability for use in appraisal is to estimate the parameters of a reduced-form utility function, where some measure of travel time variability (such as the standard deviation) is included. A recently discovered problem with this approach is that the obtained valuation will in general depen...

Many regions face through‐traffic that causes local negative externalities. Regions might respond by imposing user charges or investing in bypass transport infrastructure. In this paper two levels of decision‐making are studied: co‐operation among regions and acceptability within regions. If left to a single region, it will overcharge for usage and...

In recent years, there has been an increasing awareness that travel time reliability, apart from expected travel time, is an important component of cost-benefit analysis, especially during congested traffic conditions. A common measure of travel time reliability is standard deviation, and it has been shown that this is a theoretically sound measure...

This paper assesses the horizontal and vertical equity effects of the Stockholm Trial with Congestion Pricing for morning commuters, in terms of both travel behavioral adjustments and welfare effects, as a result of the toll's direct effects and the behavioral adjustments. We consider specifically two behavioral adjustments: mode choice and departu...

In current practice, very few Metropolitan Planning Agencies attempt to capture the effects of transportation system changes on land use, and the consequent feedback effects on transportation system performance, despite substantial evidence that these effects may be significant. In this paper, we present a case study on the application of UrbanSim,...

ABSTRACT Roadway tolling has been espoused bymany,transportation economists asan optimal solution to roadway congestion, largely due its aggregate welfare benefits. However, concerns remain about the regressivity of tolls’ benefits and burdens. This paper uses a modeling approach that explicitly represents the effects of income on choice behavior,...

This study uses non-parametric distributional comparison tools to evaluate the equity e ects of a transportation policy. I consider as a case study a congestion pricing plan for Stockholm, Sweden. This case is particularly relevant because the plan has been criticized for its potentially negative equity e ects, and the literature is so-far inconclu...

This paper contributes to the literature by estimating elasticities for factors related to the paratransit-transit mode choice decision by the elderly and disabled. The remainder of the section describes the empirical setting of the analysis, including the study location and data characteristics. Next, the methodology used to build a mode-choice mo...

Transportation (ODOT) in selecting multimodal mobility improvement projects to fund, given a budget constraint. The process involves first, the evaluation of projects using a set of criteria, incorporating such factors as cost-efficiency and modal integration, and second, the processing of the evaluation scores through a ranking algorithm. The rank...

In the current practice of mode-choice modeling, models typically focus on the more traditional choices, such as those between automobile, transit, and nonmotorized transportation. For most travelers these are, indeed, the most relevant modes. However, for some segments of the population, particularly the elderly, the choice is more limited. This s...

While congestion pricing is well known from transportation economics literature to be economically efficient, it also has a tendency to be distributed in a regressive manner unless the winners compensate the losers. In particular, it is well understood that due to a diminishing marginal value of money with income, the same toll could pose a larger...

Highway congestion in North America is widely responsible for polluting air, increasing noise, and wasting time spent in tra c, largely because drivers do not pay the full marginal cost of their own traveling decisions. Economists agree that a well-designed congestion pricing system can correct for these externalities, but there is widespread polit...

This paper examines the use of welfare-based accessibility measures for assessing the equity effects of a transport policy, with particular focus on the choice of functional form in the model of travel choice. Using a case study on Stockholm's congestion pricing trial and examining the choice of mode and destination for household shopping trips, it...

ABSTRACT When public policies are expected to affect a population in complex ways, the normal evaluation measures, such as mean effect, may fail to capture all of the effects that are important to societal goals. As an example, if the policy is expected to be “regressive”, benefiting mainly those who are already in the best position or costing main...

Thesis (Ph. D.)--University of Washington, 2006. There are myriad challenges to designing transportation policies that accomplish the dual goals of efficiency and equity and to evaluating alternative policies in an informative way. First, while a variety of equity analysis tools are available, only a few are commonly used in practice, and none can...
