Cyclist Behaviour Towards Stop Signs. A Before-After Study on Stop-Controlled Intersections Using Video Trajectory and Surrogate Methods
The installation of stop-signs in residential areas converting them from minor-approach-only stop (MAS) intersections to all-way-stops (AWS) intersections brings a positive perception by the general population. Although there is little research that has looked at the impact of AWS on cyclist behavior and their safety effects. This paper aims at investigating the safety effect of converting MAS to AWS intersections using an observational before and after approach and surrogate measures of safety (SMoS). More specifically, the impact of AWS conversion is investigated using multiple indicators including cyclist speed measures, and the postencroachment time of cyclist-pedestrian, cyclist-cyclist and cyclist-vehicle interactions. A multilevel linear model for site and approach variance, which was also used for the safety analysis, along with an ordered logit model where all the models were controlled for behavior variables, built environment features, approach and intersection geometry. The speed of the cyclist on the major approaches shows little change, while in the minor approach a systematic speed increase is presented in all the different evaluated indicators. Whereas the minor approaches have a speed increase, this is not translated to a decrease on PET or an increase of number of very dangerous interactions.
