A Traffic Signal Timing Model with Consideration on Road Configurations, Phase Planning, and Conflict Points at a Signalized T-Intersection Road

Continuous increase in demand for land transport calls for motorists’ heightened usage of roads. This interconnectivity of road infrastructures features the various types of road intersections seen worldwide. When constructed, roads may be made functional with or without traffic lights. This study will feature a traffic management system for a signalized t-intersection to mitigate vehicular traffic and road congestion. A simple single-objective optimization model was developed to minimize the traffic system’s overall cycle time and determine the green, red, and amber timing using the model and a traffic simulation to observe vehicle density, delay, and volume trends. From an unsignalized base model, three (3) signalized simulations were conducted with varying road configurations and phase plans to address conflict points in a t-intersection. A significantly efficient trend in conflict point reduction and phase planning improvement was achieved, meeting the objective of minimizing the cycle time.
