Journal ArticleDOI
Pedestrian risk decrease with pedestrian flow. A case study based on data from signalized intersections in Hamilton, Ontario
Lars Leden,Lars Leden +1 more
TL;DR: Risks for pedestrians were calculated as the expected number of reported pedestrian accidents per pedestrian, risk decreased with increasing pedestrian flows and increased with increasing vehicle flow, and promoting walking will have a positive effect on pedestrian risk at signalized intersections.
Journal ArticleDOI
Measuring the Safety Effect of Raised Bicycle Crossings Using a New Research Methodology
TL;DR: In this paper, the authors evaluated the effect of raising bicycle crossings by 4 to 12 cm and found that the paths with raised crossings attracted more than 50 percent more bicyclists and that the safety per bicyclist was improved by approximately 20 percent due to the increase in bicycle flow.
Journal ArticleDOI
Safe pedestrian crossings for children and elderly
TL;DR: Results based on field data collected at sites close to schools in Malmö, Trollhättan and Borås in Sweden, and in-depth studies and other analyses of Finnish and Swedish police-reported crashes, suggest that safety of children and elderly is further improved at sites where visibility, orientation and clarity are sufficient.
Journal ArticleDOI
An expert judgment model applied to estimating the safety effect of a bicycle facility.
TL;DR: A risk index model that can be used for assessing the safety effect of countermeasures is presented and it is concluded that the interaction between motorists and bicyclists seems to be optimal when both groups share the roadway.
Journal ArticleDOI
Safety implications of bicycle paths at signalized intersections.
TL;DR: A quantitative meta-analysis of studies evaluating, by means of the Bayesian method, the safety effectiveness of different bicycle facilities at road junctions shows that the most likely effect of introducing a cycle path is that the risk will increase by about 40% for a passing cyclist.
