LEVEL OF SERVICE ANALYSIS OF PEDESTRIAN CROSSING FACILITIES AT SIGNALIZED INTERSECTIONS UNDER HETEROGENEOUS TRAFFIC CONDITIONS

Abstract

While designing roadway facilities the pedestrian crosswalks must be given high importance, because these are the locations where pedestrians interact with vehicular traffic directly. This study aims to determine Pedestrian Perception values (PV) and assess the Level of Service (LOS) for crosswalk facilities provided for pedestrians at signalized intersections in heterogeneous traffic conditions. For this purpose, 24 crosswalks of six signalized intersections were chosen: 16 crosswalk locations were used for model development and eight crosswalk locations were used for model validation. The perception value of pedestrians was collected by conducting a questionnaire survey and traffic data was collected using a videographic survey. The parameters considered for the present study are: pedestrian volume, time is taken by the pedestrian to cross the crosswalk, length of crosswalk, pedestrian crossing speed, vehicular volume, and turning movements. The present research work proposed a mathematical model for Perception Value (PV) to assess the LOS of crosswalks of signalized intersections in urban areas. The results of the study are helpful in enhancing pedestrian safety and comfort at crosswalks.
