Abstract
Land transportation networks such as roads and other transportation facilities underpin socioeconomic development of communities by enabling fast and efficient movement of goods and people from one point to another. However, like any other infrastructures road networks are also vulnerable to natural calamities such as earthquakes and floods that disrupts the natural flow of traffic. In the occurrence of flooding incidents, several road networks are submerged in water making it impassable for traffic especially those located in low-lying areas. In this cases, traffic that were originally catered by these flooded roads will be re-routed to other alternate routes which will then affect the traffic performance of those alternate routes. This study assessed the effect of flooding events on the traffic stream performance measured through its Level of Service (LOS). Greenshields’s linear modelling was used to estimate the maximum capacity of roads based on observed data and the corresponding volume-to-capacity ratio during normal weather condition and using travel survey to estimate the additional re-routed volume to assess the volume-to-capacity ratio during flooding events. The v/c ratio for Enrile Avenue changes from 0.483 (LOS B) to 0.515 (LOS C), while the v/c ratio for Maharlika Highway changes from 0.541 (LOS C) to 1.257 (LOS F), and Lastly, Luna extension’s v/c ratio increases from 0.523 to 0.590, though the LOS remains the same. The researcher concluded that the Level of Service (LOS) in the three selected road sections were greatly affected as their v/c ratio increases. Moreover, formulating and enforcing policies on roadway clearing operations especially on the outer lanes of all major roads could help improve the traffic performance of this roads even during flooding events.
