När inte järnvägskapaciteten räcker till för alla tågoperatörers önskemål ska Trafikverket enligt järnvägslagen fördela kapacitet till olika operatörer på ett samhällsekonomiskt effektivt sätt. För att utföra detta använder Trafikverket s k prioriteringskriterier. Vi...

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...

Congestion charges were introduced in Stockholm in 2006 as a seven-month trial, followed by a referendum where a majority voted in favour of the charges. This led to the reintroduction of congestion charges in August 2007, and they have been operational since then. The system has attracted...

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...

Transit operators are interested in strategies to improve service reliability as it is an important measure of performance and level of service. One of the common practices aimed to reduce service unreliability is holding control strategies. The design of these strategies involves the selection...

Real-time information is increasingly being implemented in transit networks worldwide. The evaluation of the effect of real-time information requires dynamic modeling of transit operations and of passenger path choices. This paper presents a dynamic transit analysis and evaluation tool that...

Waiting time uncertainty is one of the main determinants of public transport reliability and overall level-of-service. The dissemination of real-time information concerning vehicle arrivals is often considered an important measure to reduce unreliability. Moreover, the prediction of downstream...

We model and test the representativeness of environmental policy-making, as implied by cost-benefit analysis (CBA) results, in governmental agencies assuming that individual civil servants maximize their personal utility. Education may also influence civil servants’ behavior. The biologists in...

In this paper we investigate how attitudes to health and exercise in connection with cycling influence the estimation of values of travel time savings in different kinds of bicycle environments (mixed traffic, bicycle lane in the road way, bicycle path next to the road, and bicycle path not in...
