Pedestrian delay is a key performance indicator for evaluating the level of service for pedestrians at signalized intersections. Although much is known about the pedestrian delay of a signalized crosswalk, the existing model in the Highway Capacity Manual 2010 cannot provide the necessary accuracy for estimating the pedestrian delay of the diagonal crossing (crossing to the diagonally opposite corner of the intersection in two stages) and the entire intersection. In this paper, a new pedestrian con- trol delay model is proposed: the model considers the diagonal crossing and moving paths. The proposed model is validated on the basis of field measurements. The main factors affecting the pedestrian control delay during diagonal crossing are discussed. Results reveal that the proposed model is promising in increasing the estimation accuracy of the pedestrian control delay of the diagonal crossing and the entire intersection (approximately 20%). The delay of the diagonal crossing increases with an increase in the time gap of the green light between the two adjacent crosswalks and an increase in the green time length of the crosswalk.
