High intensity Activated cross WalK (HAWK), as an innovative pedestrian-activated beacon, has become a hot topic and was introduced in 2009 Manual on Uniform Traffic Control Devices (MUTCD). Up till now, few studies have explored the pedestrian delay when an HAWK is installed. This paper applied the Generalized Linear Model (GLM) to model the pedestrian delay at an HAWK location. The HAWK pedestrian delay model includes the major street arrival rate, minor street arrival rate, pedestrian arrival rate, and the distance between HAWK and intersection. By using VISSIM, the operation of HAWK was simulated to provide data for HAWK pedestrian delay modeling. Four different functional forms were investigated in this paper in order to select an appropriate one that could more accurately model pedestrian delay. Based upon the results of training and validating datasets, it can be indicated that the HAWK pedestrian delay model developed in this study is capable of effectively evaluating the pedestrian delay with a satisfactory accuracy.
