International transferability of accident modification functions for horizontal curves
(Journal article; Peer reviewed, 2013-07-18)Studies of the relationship between characteristics of horizontal curves and accident rate have been reported in several countries. The characteristic most often studied is the radius of a horizontal curve. Functions ... -
Interpreting interaction effects in estimates of the risk of traffic injury associated with the use of illicit drugs
(Journal article; Peer reviewed, 2018-02-08)Interactions characterise the relationship between use of amphetamines, cannabis and opiates as a driver and the risk of traffic injury associated with the use of these drugs. Inverse risk curves have been found for these ... -
Methodological guidelines for developing accident modification functions
(Journal article; Peer reviewed, 2015-04-04)This paper proposes methodological guidelines for developing accident modification functions. An accident modification function is a mathematical function describing systematic variation in the effects of road safety ... -
The more (sharp) curves, the lower the risk
(Peer reviewed; Journal article, 2019-10-07)The risk of accident in horizontal curves is a complex function of at least the following characteristics of the curve: the radius of the curve; the length of the curve (and the resultant deflection angle); the presence ... -
Road safety effects of roundabouts: A meta-analysis
(Journal article; Peer reviewed, 2017-01-05)This paper presents a meta-analysis of the road safety effects of converting junctions to roundabouts. 44 studies containing a total of 154 estimates of effect were included. Based on a meta-regression analysis, converting ... -
Safety effects of fixed speed cameras - An empirical Bayes evaluation
(Journal article; Peer reviewed, 2015-06-27)The safety effects of 223 fixed speed cameras that were installed between 2000 and 2010 in Norway were investigated in a before–after empirical Bayes study with control for regression to the mean (RTM). Effects of trend, ... -
Safety in numbers for cyclists – conclusions from a multidisciplinary study of seasonal change in interplay and conflicts
(Journal article; Peer reviewed, 2016-05-28)In many European countries, it is a political goal that future growth in local travel should be absorbed by sustainable transport modes. Concerns that increased walking and cycling produce more accidents have been countered ... -
Safety-in-numbers: An updated meta-analysis of estimates
(Journal article; Peer reviewed, 2019-05-28)Safety-in-numbers denotes the tendency for the number of accidents to increase less than in proportion to traffic volume. This paper updates a meta-analysis of estimates of safety-in-numbers published in 2017 (Elvik and ... -
Safety-in-numbers: Estimates based on a sample of pedestrian crossings in Norway
(Journal article; Peer reviewed, 2016-03-16)Safety-in-numbers denotes the tendency for the risk of accident for each road user to decline as the number of road users increases. Safety-in-numbers implies that a doubling of the number of road users will be associated ... -
Some implications of an event-based definition of exposure to the risk of road accident
(Journal article; Peer reviewed, 2015-01-02)This paper proposes a new definition of exposure to the risk of road accident as any event, limited in space and time, representing a potential for an accident to occur by bringing road users close to each other in time ... -
Speed enforcement in Norway: Testing a game-theoretic model of the interaction between drivers and the police
(Journal article; Peer reviewed, 2015-09-03)This paper probes the relationship between changes in the risk of apprehension for speeding in Norway and changes in the amount of speeding. The paper is based on a game-theoretic model of how the rate of violations and ... -
A systematic cost-benefit analysis of 29 road safety measures
(Journal article; Peer reviewed, 2019-10-01)Economic evaluations of road safety measures are only rarely published in the scholarly literature. We collected and (re-)analyzed evidence in order to conduct cost-benefit analyses (CBAs) for 29 road safety measures. The ... -

The turning point in the number of traffic fatalities: Two hypotheses about changes in underlying trends
(Journal article; Peer reviewed, 2014-10-23)The number of traffic fatalities reached a peak in many highly motorised countries around 1970. Some previous studies have suggested that the turning point in the number of traffic fatalities was inevitable and did not ... -
Traffic volume and crashes and how crash and road characteristics affect their relationship – A meta-analysis
(Peer reviewed; Journal article, 2020-08-07)The present study has investigated the relationship between traffic volume and crash numbers by means of meta-analysis, based on 521 crash prediction models from 118 studies. The weighted pooled volume coefficient for all ... -
Under-reporting bicycle accidents to police in the COST TU1101 international survey: Cross-country comparisons and associated factors
(Peer reviewed; Journal article, 2017-10-26)Police crash reports are often the main source for official data in many countries. However, with the exception of fatal crashes, crashes are often underreported in a biased manner. Consequently, the countermeasures adopted ... -
Updated estimates of the relationship between speed and road safety at the aggregate and individual levels
(Journal article; Peer reviewed, 2018-11-23)Recent studies of the relationship between the speed of traffic and road safety, stated as the number of fatalities and the number of injury accidents, are reviewed and their results synthesised by means of meta-analysis. ... -
Vehicle registration year, age, and weight – Untangling the effects on crash risk
(Journal article; Peer reviewed, 2018-11-15)The aim of the present study was to investigate the effects of passenger cars’ first year of registration, weight, and age on the number of killed or seriously injured (KSI) car drivers, pedestrians, and cyclists. Poisson ... -
What would a road safety policy fully consistent with safe system principles mean for road safety?
(Journal article; Peer reviewed, 2023-10-06)If fully implemented, the Safe System principles as formulated by the International Transport Forum would lead to a considerably safer road transport system. The aims of this paper are: (1) To define operationally what ...
