ABOUT

This respo is a tool produced from a research project that aims to identify the behaviors of turning vehicles yeilding pedestrians/bicyclists/scooters at inertersections using video processing technologies. Yielding behaviroes are an improtant surregate safety measures to represent pedestrian safety at urban intersections. This tool provides a rapid and low-cost safety diagnosis approach for proactive pedestrian safety analysis.

The tool include four components:

1. object detection (YOLO V3)
2. object track (alogorithm developed in this study)
3. yield behavior identification
4. assess pedestrian safety based on identified yield behaviors

QUICK START (Ubuntu)

Install Oracle Java 8 on Ubuntu.

$ sudo add-apt-repository ppa:webupd8team/java
