- W788402928 abstract "More than 14% of the about 25,000 people killed each year in road crashes in European Countries are pedestrians (1). The relevance of the problem led transportation researchers to consider the improvement of pedestrian safety like a priority. For crashes involving pedestrian, the lack of performance models based on crash data is due to the spread distribution of the data that make difficult to identify statistical correlations. In spite of traditional reactive strategies based on crash history analysis, overly depending from the quality and availability of the crash data, surrogate safety measures were developed as an efficient preventive approach. Traffic Conflict Technique (TCT) was developed as “surrogate measure of road safety” by using near-accident indicators based on measures of spatial and temporal proximity of road users. In the paper, a new indicator of conflict, named Pedestrian Risk Index (PRI), has been proposed, linking both probability of collision between vehicle and pedestrian and severity of the consequences (2). As case study and in order to evaluate the safety performance of new traffic calming devices installed replacing zebra marked crosswalks, a before-after study was carried out in Spain using PRI as surrogate measure of safety. The application of the Pedestrian Risk Index showed that PRI is effective to highlight modifications in drivers’ behavior due to installation of different safety countermeasures at a crosswalk, highlighting for a reduction in severity of conflicts with an expected propensity to improvement in pedestrian safety." @default.
