Pedestrians Crossing Behavior Models on Midblock Suburban Area in Dohuk City

Abstract

In this study, ten pedestrian crossing spots located in Dohuk City suburban area were selected to make analysis and evaluation to the behavior of the people crossing the main streets, and walking on sidewalks according to their genders. Data was collected using double video cameras fixed on selected points to observe pedestrian movements along crossings and sidewalks, their interaction with drivers, and vehicles conflicting them. Data compiled was classified and presented to measure numbers of moving vehicles, people, vehicle gaps, space, pedestrian unit flow, speeds of both pedestrians and vehicles passing the crossing lines on suburban midblock. Data was presented using Dohuk City GIS up-to-date map taken from the city Municipality Directorate. Data analysis was implemented, and different empirical models were chosen to study the different interactions and effects of human, geometric, and vehicular traffic parameters on the behavior of pedestrians crossing, and walking on crosswalks and sidewalks respectively. Results show that in crosswalks, pedestrian flow with their speeds were polynomial in nature, while unit flow and speed relationships with density were linearly correlated. The relation between unit flow and their speed (for both male and female) on suburban sidewalks is Polynomial 2nd degree, and the optimum walking speed obtained is 1.16 and 1.0 m/sec for male and female respectively, with minimum walking speed for females are lower than male but the maximum walking speed is similar.
