This study focuses on the conflicts between cars and bicycles in mixed traffic and their impact on speed and safety. It aims to improve the situation by investigating an approach that separates bicycles and cars onto different roads within a network. Various scenarios were compared to a baseline, considering factors such as traffic volume, modal share, and road hierarchy. The performance of each scenario was evaluated from the perspectives of motorists and cyclists, considering car and bicycle efficiency for different trip lengths and the level of cycling stress assessed using the LTS score. The methodology involved estimating travel times using a traffic simulator and generating reachable areas for bicycles and cars using ArcGIS. The study contributes to providing insights for designing multi-modal transportation systems that consider both the benefits of shared road spaces and the potential advantages of separating bicycles and cars onto different roads.
