The paper proposes a framework that combines computer vision technologies and predictive models to evaluate the potential risk of pedestrians at intersections in real-time. The framework aims to predict the arrival time of pedestrians and vehicles, using deep learning models to calculate the Predicted Post-Encroachment Time (P-PET). This surrogate safety measure is used to identify potential risks, with the goal of preventing accidents. To improve the effectiveness and reliability of risk evaluation, the paper classifies pedestrians into distinct categories and applies specific evaluation criteria for each group. The results show that the framework can effectively identify potential risks using P-PET, making it a feasible solution for real-time applications.

The researchers want to make intersections safer by predicting when people might get hurt. They’re working with computer vision and special models to figure out how likely someone is to get hit at an intersection. The main challenge is creating a way to quickly measure this risk, so they developed a new method called Predicted Post-Encroachment Time (P-PET). This helps them spot potential dangers faster. To make it even better, they sorted people into groups and used different rules for each group. So far, their approach has been successful in finding risks and could be used to help keep people safe.
