A Study on Traffic Signal System at Lacson- Espaňa Intersection for Optimization
Abstract
The worsening traffic congestion has a major impact on the day to day activities in Manila, Philippines. The existing traffic signalization systems used in the Lacson – Espaňa, intersections are fixed-time control and it faces traffic congestions during peak time. Hence, in this work, an assessment was conducted to evaluate whether the current traffic system is optimal since the intersection is observed to be congested. The traffic assessment was done at Lacson – Espaňa intersections in Sampaloc, Manila during their peak hours of 7:00AM – 8:00AM and 1:00PM – 2:00PM.Oversaturation Severity Index (OSI) was utilized to analyze the traffic congestion. Results showed that lanes in the AM session were under the case of residual queues which contributed to the congestions.
