Pedestrian Delay at Signalized Intersections with a Two-Stage Crossing Design

An improved pedestrian delay model was developed for signalized intersections with a two-stage crossing design. This model provides a timely enhancement tool for the Highway Capacity Manual for conducting multimodal-oriented level of service assessments at signalized intersections with unconventional pedestrian crossings. The proposed model is presented in a general form that provides estimation of three portions of pedestrian delay involved in a two-stage crossing: the first-stage delay; the second-stage delay for pedestrians who crossed during the Walk phase of the first stage; and the second-stage delay for pedestrians who crossed during the flashing Don't Walk and Stop phases of the first stage. The model was validated through microscopic simulation under a wide range of traffic scenarios. Statistical analysis suggests that the proposed model is able to give satisfying results (R² = 99.9%, p-value = .000). The model can be applied in various cases knowing some basic input parameters and variables.
