Abstract
As part of the ARCADE project, this study is aimed at identifying the main collision patterns involving VRUs in urban areas and to find the contributing factors that lead to risky conditions, also considering multiple interactions between road users. The corridor of Corso Vittorio Emanuele II in Turin, Italy, was selected for this study. Based on the official ISTAT crash database, collision diagrams were developed to evaluate the dynamic of collision between vehicles and VRUs, and then used to design the simulation scenarios. The patterns showed that the most hazardous conditions for VRU occurred on the two service roads of the corridor, and that the differences in such road layouts have led to different crash frequencies and severities.
In the corridor section between Piazza Rivoli and Piazza Adriano, a dedicated cycle lane separated from ordinary traffic lanes has led to lower collisions frequencies and severities, while the corridor from Piazza Adriano to Porta Nuova, the service roads is a shared lane for both vehicles and bicycles with higher crash frequency and severities
