The impact of policy instruments supposed to reduce greenhouse gas emissions from road freight transports may seem smaller than expected. Using insights from economics and contract theory, the paper sorts out the (possible) instances of market failure in the freight transport market; operator...

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...

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...

The paper analyses why CO2 emissions from heavy road freight transports increase in spite of higher fuel prices. Swedish time series data for the period 1990-2011 are analyzed with help of indicators. The logistic efficiency of the road transports improved especially in the 1990-ties due to the...

In the debate of climate change and mitigation of greenhouse gases, the issue of energy use is closely related. Several political aims concern the need to reduce the overall energy demand in the society, where transportation is an important contributor. In the transport sector, major efforts...

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...
