This research is to develop a microscopic, time step and behavior based simulation model to model the traffic operations within the planned fifth street corridor area. The program analyzes the traffic operations under constraints such as lane configuration, traffic composition, traffic signals, transit stops, etc., thus making it a useful tool for the evaluation of various design alternatives based on planning measures of effectiveness.

This study focuses on the comparison of two scenarios: the current plan with modification to F&G street signals and the road diet plan. Their performances are evaluated and compared in terms of vehicle speed, total stops, total delay time, queue length at the intersection, etc. In the “road diet” scenario, new signal timing plan will be proposed to optimize the operation of the whole planning area.
