Evaluation Of Traffic Safety By Using Time To Collision: A Case Study Of Rajkot City

Abstract

Traffic safety is extremely important, especially on city streets where traffic volumes are high and traffic conflicts are common. As a result, it is critical to design a methodology for assessing traffic safety. The study's issues are as follows: The common roadway is used by a large number of venerable road users and vehicular traffic. Driving standards are poor, and traffic safety is limited along that section of the road. The time to collision (TTC) samples from traffic videos taken from kotecha circle to indira circle with different locations and traffic conditions are first analyzed in this paper. However, according to field survey data, a lateral separation between the leader and the follower occurs frequently in complex traffic conditions. As a result, we redefined the time-to-collision equation by taking in lateral separation (TTC). TTC samples can be categorized into three groups: risky scenarios, relative safe situations, and absolute safe situations. Following that, the proposed traffic safety indictor is used to represent the assessment results of urban road traffic safety.
