Explaining variation in safety performance of roundabouts.
The conversion of an intersection into a roundabout has been proven to reduce generally the number of crashes with injuries or fatalities. However, evaluation studies frequently showed considerableExpand

The effects of roundabouts on traffic safety for bicyclists: an observational study.
A before-and-after study was carried out of injury accidents involving bicyclists on 91 roundabouts in Flanders-Belgium. The study design accounted for the effects of general safety trends andExpand

Injury crashes with bicyclists at roundabouts: influence of some location characteristics and the design of cycle facilities.
PROBLEM Previous research indicated that conversions of intersections into roundabouts appear to increase the number of injury crashes with bicyclists. However, it was assumed that the effectivenessExpand

Externality of risk and crash severity at roundabouts.
The severity of 1491 crashes on 148 roundabouts in Flanders-Belgium was examined in order to investigate which factors might explain the severity of crashes or injuries and to relate these factors toExpand

In search of the severity dimension of traffic events: Extended Delta-V as a traffic conflict indicator.
Most existing traffic conflict indicators do not sufficiently take into account the severity of the injuries resulting from a collision had it occurred. Thus far, most of the indicators that haveExpand

Extended prediction models for crashes at roundabouts
This paper builds upon the results of previously developed crash prediction models for roundabouts. The originally investigated sample was extended from 90 to 148 roundabouts. Poisson and gammaExpand

Safety effects of reducing the speed limit from 90km/h to 70km/h.
Speed is one of the main risk factors in traffic safety, as it increases both the chances and the severity of a crash. In order to achieve improved traffic safety by influencing the speed of travel,Expand

Additional road markings as an indication of speed limits: results of a field experiment and a driving simulator study.
Although speed limits are indicated by road signs, road users are not always aware, while driving, of the actual speed limit on a given road segment. The Roads and Traffic Agency developed additionalExpand

Automated section speed control on motorways: an evaluation of the effect on driving speed.
Automated section speed control is a fairly new traffic safety measure that is increasingly applied to enforce speed limits. The advantage of this enforcement system is the registration of theExpand

Socioeconomic and sociodemographic inequalities and their association with road traffic injuries
Abstract Increasing evidence suggests that neighborhood-based measures of socioeconomic status are correlated with traffic injury. The main objective of this study is to determine the differences inExpand
