Evaluation of the Effects of Traffic Signalization at the Lopez Avenue-National Highway, Los Baños Laguna Intersection Using Philippines Local Simulation Software

Abstract

Due to the increasingly complex and tedious work of traffic data analysis, various traffic simulation software was developed to increase efficiency and convenience when conducting traffic analysis. In the Philippines, the Intelligent Transport Systems of the University of the Philippines Diliman also developed a traffic simulation software known as Philippine Local Traffic Simulator (LocalSim). This study aims to assess the effectiveness of the implementation of signal lights at the National Highway-Lopez Avenue intersection located at Los Baños, Laguna. The traffic data used was obtained from 2014 and 2019 for the unsignalized and signalized intersection, respectively. A simulation model for the intersection was created for both unsignalized and signalized scenarios. Based on the results of the paired t-test, the implementation of signal lights worsened the traffic condition, increasing average travel time and decreasing average travel speed in the road links of the intersection.
