Pedestrian Arrival and Release Characteristics at Signalized Crosswalk
- 18 Downloads
The paper applied the shock wave theory to analyze the characteristics of pedestrian arrival and release, considering different related factors (i.e., crosswalk width, length, and signal timing). Then pedestrian release model with two constraints was established on the strength of above study. At last, correlation parameters were calibrated with the practical pedestrian data, and the lateral distance between pedestrians is shown as 0.8 m. The proposed model can be used in following two ways: the optimization of crosswalk width and the evaluation of crosswalk capacity to accommodate the demand. The result could offer some references to protect the safety of pedestrians and improve the crosswalk capacity.
