Signalized Midblock crosswalk (SMC) is a location where pedestrian and vehicular flows are segregated by a traffic signal.

摘要

Signalized Midblock crosswalk (SMC) is a location where pedestrian and vehicular flows are segregated by a traffic signal. The present paper aims to model the pedestrian crossing time at SMC under mixed traffic conditions. The proposed crossing time was developed by considering the bidirectional effect of pedestrians at SMC. Eight SMC from Hyderabad (India) were selected for the study. The delay that occurred due to the bidirectional effect is termed as frictional delay in this paper and the total crossing time of pedestrians was modeled as the sum of ideal crossing time (length of the crosswalk/15th percentile speed of pedestrians) and frictional delay. The final crossing time model was validated with the internal data and external data using Key Performance Indicators (KPI) like RMSE, MAPE, NSE, and RSR. Results revealed that the proposed model is accurate in estimating the pedestrians crossing time at SMC. The developed crossing time model can be a useful tool for designers and planners in estimating the crossing time at SMC and further designing the facilities.
