Through this study, we were able to identify the following:
- There is bell-shaped region in front of the vehicle which can be considered abnormal and dangerous for bicyclists. This region must be a focus in the design of PCS systems.
- We were able to estimate the lateral position of bicyclists moving in a direction parallel to the vehicle's path. The median position of bicyclists relative to the vehicle on the right side was 3.9 meters, and on the left side was 4.4 meters. This data will be used to inform PCS test scenarios.
- We were able to estimate vehicle and bicycle speeds in limited conditions. The median of vehicle speed was 19.8 mph, and the median bicycle speed was 16.7 mph, information that will be used to inform PCS test scenarios.
This is a project in collaboration with the Transportation Active Safety Institute (TASI), Indiana University, Purdue University and the Ohio State University.
