This paper explores the influence of individuals’ environmental attitudes and urban design features on travel behavior, including mode choice. It uses data from residents of 13 new neighborhood UK developments designed to support sustainable travel. It is found that almost all respondents were...

A number of highly cited papers by Flyvbjerg and associates have shown that ex-ante infrastructure appraisals tend to be overly optimistic. Ex post evaluations indicate a bias where investment cost is higher and demand lower on average than predicted ex ante. These authors argue that the bias...

The paper challenges the existing sustainable transport literature. Most sustainable transport plans focus on the reduction of greenhouse gas emissions in either one region or country and this neglects two handicaps of strong unilateral action. The first is that climate is a global commons...

We estimate the value of time savings, different cycling environments and additional benefits in cost-benefit analysis of cycling investments. Cyclists’ value of travel time savings turns out to be high, considerably higher than the value of time savings on alternative modes. Cyclists also...

This paper presents some experience from using transport models in Swedish planning practice. First we outline three recent examples of planning settings in which transport models have been put to extensive use. For the Swedish ‘national’ transport plan for the period 2010–2021, which was...

Cost overrun of transport projects is one of the most important problems in transport planning. It also makes the result of the cost-benefit analyses uncertain, thus decreasing their usefulness for decision making. In recent years more emphasis has been put on improving cost calculations and...

The purpose of this paper is to analyze the climate benefit of investments in high speed rail-way lines given uncertainty in future transport demand, technology and power production. To capture the uncertainty of estimated parameters, distributions for the annual traffic emissions reduction...

We explore how benefit-cost efficiency and electoral support affect road investment decisions in Sweden and Norway. In Norway, neither benefits nor costs seem to affect project selection. In Sweden, civil servants’ decisions are strongly affected by projects’ benefit-cost ratios, with a...

This paper performs an ex-post cost-benefit analysis (CBA) of the Metro system in Stockholm built in the 1950s. We find that the Metro was socially beneficial and that the largest benefit of the Metro is its capacity, making it possible for many people to travel to and from the city center. We...

Cost-Benefit analysis (CBA) is sometimes criticized for not taking account of induced demand due to planning policy or relocalization triggered by large infrastructure investments. There is also a notion among planers and decision makers that accounting for these effects can underestimate the...
