Crosswalk capacity under mixed traffic conditions at signalized intersection with channellized islands

In order to re-estimate the crosswalk capacity under mixed traffic condition, a new approach to calculating the crosswalk capacity at signalized intersections with channelized islands is demonstrated. Channelized intersections designate the intended vehicle paths using pavement markings or raised islands. Channelization is widely used for crosswalks, particularly when there is a non-motorized traffic (e.g., pedestrians and bicycles) waiting zone. The capacity of crosswalk is changed due to the two distinctive stages when non-motorized traffic goes through signalized intersections during the green time. The capacity calculation model is based on the dynamics area conversion of pedestrians, bicycles, electric bicycles and conversion of reach area. The model is then calibrated using the field data collected at several signalized intersections in the city of Fuzhou. The proposed method in this paper can better estimate the capacity of crosswalk. © right.
