The paper analyzes the political acceptability of policies targeted at relieving urban congestion. The paper combines a stylized model of an urban transport network with a somewhat more detailed model of the political process that incorporates interactions between voters, special interest groups...

This paper addresses the lack of reliability within the Swedish rail network by identifying passenger train delay distributions. Arrival delays are analyzed in detail using data provided by the Swedish Transport Administration, covering all train departures and arrivals during 2008 and 2009. The...

In this paper we examine the stochastic properties that long term aggregate traffic demand exhibits. Based on the results of the time series analysis, we examine how fractionally integrated processes affect real option valuation in road projects. We conclude that the long memory property we find...

Shifting transportation to electrified modes, e.g., rail, is a politically attractive way of reducing greenhouse gas (GHG) emissions from the transportation sector. There is a vivid debate about the effects such a shift has on GHG emission and how these should be assessed and appraised. We argue...

This paper proposes a novel method for estimating the traffic demand risk associated with transportation. Using mathematical properties of wavelets, we develop a statistical measure of traffic demand sensitivity with respect to GDP. This measure can be adapted in a flexible way to capture risk...

In this paper, renewal costs for railway tracks are investigated using survival analysis. The purpose is to derive the effect from increased traffic volumes on rail renewal cycle lengths and to calculate associated marginal costs. A flow sample of censored data containing almost 1 300...

Many cities have seen public support for congestion charges increase substantially after charges have been introduced. Several alternative explanations of this phenomenon have been suggested, but so far little evidence has been available to assess the relative importance of these explanations....

We explore what variables influence public attitudes towards congestion charges using a survey carried out in Stockholm, Helsinki and Lyon, three European cities with many similarities but with different experiences and discourses with respect to congestion charging. We find that self-interest...

This is the first paper in the literature to formally study the cost impact of competitive tendering in rail maintenance. Sweden progressively opened up the market for rail maintenance services, starting in 2002. We study the cost impacts based on an unbalanced panel of contract areas between...

Congestion pricing was introduced in Stockholm 2006, first as a trial followed by a referendum, and permanently from 2007. Public attitudes to the charges became more negative during the period from the decision to the start of the system. Once the system started, public attitudes became...
