A method to evaluate equitable accessibility: Combining ethical theories and accessibility-based approaches

In this paper, we present the case that traditional transport appraisal methods do not sufficiently capture the social dimensions of mobility and accessibility. However, understanding this is highly relevant for policymakers to understand the impacts of their transport decisions. These dimensions include the distribution of mobility and...

Kostenoverschrijdingen in transportinfrastructuurprojecten in Nederland en wereldwijd: Kenmerken en determinanten van kostenoverschrijdingen

In Nederland komen kostenoverschrijdingen minder vaak voor en is de gemiddelde overschrijding lager dan in andere landen. Het grootste deel van de kostenoverschrijding komt voor in de fase voor de start van de bouw. De gemiddelde kostenoverschrijding is het kleinst voor spoorwegen gevolgd door wegen en kunstwerken. Spoorwegen en bruggen in...

Cost Overruns in Large-scale Transportation Infrastructure Projects: Explanations and Their Theoretical Embeddedness

Managing large-scale transportation infrastructure projects is difficult due to frequent misinformation about the costs which results in large cost overruns that often threaten the overall project viability. This paper investigates the explanations for cost overruns that are given in the literature. Overall, four categories of explanations can...

The trade-off between CO2 emissions and logistics costs based on multi-objective optimization

This paper develops a decision-support tool for estimating the balanced market shares of given freight transport systems operating in a given network, satisfying both the minimum costs and the Carbon-Dioxide (CO2) emission requirements. Since CO2 constraints in logistics markets need to be realized in the near future, a modal shift in freight...

Accessibility and ICT: A review of literature, a conceptual model and a research agenda

Over the past two decades many papers are published in the area of ICTs impact on travel behaviour. Literature focusing on the impacts of ICT on accessibility is relatively scarce. In this paper we give an overview of impacts of ICT on four components of accessibility as distinguished by Geurs and Van Wee (2004): (1) the land-use component, (2)...

Self-selection: A key to a better understanding of location choices, travel behavior, and transport externalities?

In the last decade the importance of attitude-related residential self-selection has frequently been recognized. In addition people can theoretically self select them with respect to other location choices, such as job locations, with respect to travel behavior, or with respect to the exposure to transport externalities such as noise and...

Travel information as an instrument to change cardrivers’ travel choices: A literature review

This paper aims to provide insights that help transport academics and policy makers appreciate the potentials and limitations of information provision as a means to changing car-drivers’ travel choices. The focus is on a modal shift from private car to public transport and changes in car-drivers’ choices for departure times and routes towards a...

Safeguarding both accessibility and the environment: The Dutch view on infrastructure
