Tracking Pedestrians Under Occlusion in Parking Space

Abstract

Many traffic accidents occur in parking lots. One of the serious safety risks is vehicle-pedestrian conflict. Moreover, with the increasing development of automatic driving and parking technology, parking safety has received significant attention from vehicle safety analysts. However, pedestrian protection in parking lots still faces many challenges. For example, the physical structure of a parking lot may be complex, and dead corners would occur when the vehicle density is high. These lead to pedestrians' sudden appearance in the vehicle's path from an unexpected position, resulting in collision accidents in the parking lot. We advocate that besides vehicular sensing data, high-precision digital map of the parking lot, pedestrians' smart device's sensing data, and attribute information of pedestrians can be used to detect the position of pedestrians in the parking lot. However, this subject has not been studied and explored in existing studies. To fill this void, this paper proposes a pedestrian tracking framework integrating multiple information sources to provide pedestrian position and status information for vehicles and protect pedestrians in parking spaces. We also evaluate the proposed method through real-world experiments. The experimental results show that the proposed framework has its advantage in pedestrian attribute information extraction and positioning accuracy. It can also be used for pedestrian tracking in parking spaces.

Accident Diagnosis and Evaluation System in Parking Lots Using Multisource Data Based on Bayesian Networks

“…Meanwhile, despite the low vehicle speeds in the parking lots, frequent blind spots and narrow entrances, and exit ramps raise safety concerns and could cause property damage and casualties. Research on pedestrian tracking under parking lot occlusion [13], real-time positioning of vehicles in underground parking lots based on high-precision maps, and multisensor fusion positioning have also been highly discussed [14]. Te dual impact of ITS and complex internal environments may create new parking safety issues.…”
