The Identification of Effective Variables on the Pedestrian Safety In Conflict With Motorcycles at Non-Signalized Intersections Based on Time to Collision

The level of safety of transportation being low often considers an obstacle to sustainable development. Pedestrian safety is one of the essential problems, researchers of the safety of transportation face. Since non-signalized intersections lack the controllers of safety and have many conflicts between pedestrians and vehicles, are considered to be a dangerous place for pedestrians. The conflict between pedestrians and motorcycles and the variables which influence those conflicts are the issues that are not paid enough attention by researchers. The data used in this paper have been achieved using the image processing method. The effects of the variables related to the pedestrians and the motorcycles on Time to Collision (TTC) have been estimated using a linear regression model. The intersection assessed in this article is located where Vesal-Shirazi (the major street) and Bozorgmehr(the minor street) street meet together. Finally, in the reliability of 95 percent, the variables such as the direction of the pedestrian movement, the pedestrians moving in a group and the direction of motorcycle movement significantly influenced TTC with the numbers -0.22, 0.28, and -0.32 respectively.
