Presentation Title: Automated Safety and Usability Assessment Methods for Outdoor Street Crossings
Abstract:
Pedestrians (including wheeled mobility device users) can face safety and usability challenges at street crossings because of the inherent risks associated with winter weather, low lighting levels, and by interactions with other road users (e.g., bicycles, vehicles). Each of these environmental factors have both physical and psychological influences on the perceived safety and risk of fall and injury. As a result, many older adults and persons with disabilities choose to reduce their outdoor activity levels and become more isolated in their homes, restricting their daily mobility, and potentially triggering a downward spiral of deconditioning, frailty, and physical decline.
However, these challenges have gotten limited attention, likely because of a lack of efficient methods for practical analysis of pedestrian movements and interactions with external risk factors in real-world outdoor settings. The objective of this project is to develop an automated pedestrian detection and tracking system that can help assess the behavior of pedestrians and understand the day-to-day challenges these at-risk road users face at street crossings in urban environments.
The pedestrian street crossing evaluation system will use a portable video recording setup that includes a 4k video camera (Z-CAM E2) mounted on a 10 m tall mast to capture the movements of pedestrians and other road users. Computer vision approaches including YOLOv7 and DeepSORT will be used automate the detection and measurement pedestrian walking speed and trajectory, as well as the classification of conflicts between pedestrians and other road users.
This project will provide new automated observation tools for evaluating the safety and usability of street crossings. The goal of this work is to understand the complex relationship between pedestrians and the built environment and highlight limitations in current infrastructure design and/or maintenance so that they can be made safer and more accessible for all individuals.
