Evaluating Traffic Signal Implementation at Sta. Ana, Pampanga T-Intersection Along Jose Abad Santos Avenue

Abstract

Traffic congestion is one of the most common social and economic transportation problems in urban areas, and it affects the economy, environment, and daily lives of the people. The congestion at the three-way junction or T-Intersection at Jose Abad Santos in San Joaquin, Santa Ana, Pampanga dramatically affects the residents of Santa Ana and the nearby towns such as Arayat and Candaba. This study aimed to determine if installing traffic lights will improve traffic flow in the T-Intersection at Jose Abad Santos in San Joaquin, Santa Ana, Pampanga. The researchers focused on evaluating the effectiveness of installing traffic lights during peak hours provided by the municipal ordinance in Sta Ana, Pampanga, to provide comprehensive data and an understanding of the traffic conditions at the T-intersection. To determine the effectiveness of the traffic lights, the researchers analyzed and compared the data needed, which is traffic volume data, specifically the Level of Service (LOS) of the current T-Intersection and compared it with signalized intersections through computer simulation using PTV Vissim. Based on findings, the data showed that the unsignalized T-intersection has a LOS Rating F and VCR greater than 0.60 and the signalized T-intersection through simulation in PTV Vissim has a LOS rating E. The researchers concluded that the installation of the traffic light would improve the traffic flow of the T-Intersection at Jose Abad Santos in San Joaquin, Santa Ana, Pampanga, as the LOS rating of the intersection improved from F to E after installing the traffic light in the T-Intersection but the overall traffic in the T - Intersection was not fully controlled according to several traffic standards.
