Marginal railway track renewal costs

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...

To evaluate the level of safety of rail traffic in Sweden

The Swedish National Road and Transport Research Institute (VTI) has been commissioned by The Swedish Transport Agency to analyse if the latter’s existing data can be used to estimate the level of safety of rail traffic in Sweden in a manner meeting...

Marginal cost estimation for level crossing accidents

This study examines the relationship between train traffic and the accident risk for road users at level crossings. The marginal effect of train traffic on the accident risk can be used to derive the marginal cost per train passage that is due to...

Valuing in-vehicle comfort and crowding reduction in public transport

This report is a Swedish summary of: Björklund, G. & Swärdh, J-E. (2015). Valuing in-vehicle comfort and crowding reduction in public transport. CTS Working Paper 2015:12. http://swopec.hhs.se/ctswps/abs/ctswps2015_012.htmThe purpose of the present...

Regress – relevant for Sweden’s railway sector?

VTI has been commissioned to analyze the preconditions for, and possible consequences of introducing the possibility of regress in the railway industry. Regress refers to the possibility of anyone that is stricken by financial consequences of train...

Valuation of travel time savings in pedestrian and bicycle trips

This report consists of three summaries of studies, conducted at VTI, concerning cyclists’ valuation of travel time savings on different types of bicycle paths and pedestrians’ valuation of travel time savings on footh paths. In the bicycle studies...

A review of information regarding train delays year 2012

The purpose of this report is to document the quality of data from the Swedish Transport Administration regarding train delays, in order to assess whether it can be used to deepen the understanding of the size of the delays and the conditions that...

Pedestrians’ valuations of footpaths

The background to this study is an inquiry by the Swedish Transport Administration to develop methods for benefit-cost analyses for pedestrians’ appraisals of their walking environment and how different improvements in the environment affect...

Influences of infrastructure and attitudes to health on value of travel time savings 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...

Forecasting the impact of infrastructure on Swedish commuters’ cycling behaviour

In this paper we investigate the impact of four cycling environments on the propensity to cycle to work. The types of infrastructure investigated were mixed traffic, bicycle lane in the road way, bicycle path next to the road, and bicycle path not...

Valuation of travel time savings in bicycle trips

The background to this study is that the Swedish Transport Administration wants to develop methods for benefit-cost analyses of infrastructure investments for bicycling. An important item in such appraisals is often the travel time value. The aim of...

Marginal railway track renewal costs

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...

Driver irritation and aggressive behaviour

A sample of 98 drivers responded to a Swedish version of the UK Driving Anger Scale [UK DAS; [Lajunen, T., Parker, D., Stradling, S.G., 1998. Dimensions of driver anger, aggressive and highway code violations and their mediation by safety...

Driver behaviour in intersections

Drivers' behaviour in intersections is not only influenced by the rules of priority in the intersection but also by the design of the intersection as well as the behaviour of other road users. If behaviours that supplement or contradict formal...
