Study on the Effect of Variation in the Geometric Parameters of the Work-Zone on Traffic Safety Using the Simulation Approach

From a safety and capacity perspective, road transit is a crucial means of transportation. It is one of the difficult components to comprehend the performance of the road network, especially in terms of efficiency and safety on the roads. The need for road transportation is very high because of a constant increase in traffic demand. Road maintenance and construction activities are fairly prevalent and produce a variety of work-zones. Work-Zone of any road is critical from both safety and capacity points of view. Work-Zone safety-related issues are very critical from both operation and maintenance points of view. Work-Zone geometry has a significant effect on both traffic safety and capacity. Various work-zone geometric parameters are length of work-zone, lane-drops of work-zone and tapering length of work-zone. The research paper studies the effect of variation in the geometric parameters of the work-zone on traffic safety using a simulation approach. The research paper studies the geometric parameter variation of work-zone on traffic safety at the microscopic level using various microscopic parameters such as box and whisker plots, descriptive statistics, trajectories, hysteresis plots and conflict probability.
