Abstract

Frequently, the rainstorm in Makassar City, Indonesia have caused water puddle at the surface of arterial roads which influenced the traffic performance in the roads. The present study aims to simulate the changing of the traffic performance on a primary arterial road in the city, namely Pettarani Street, which has four lanes of each traffic direction. The traffic survey consists of traffic count and vehicle speed measurement during two hours of the afternoon peak hour at eight segments of the road. The first step analysis develops a relationship model between the traffic volume and the vehicle speed. Regarding the model, this study simulates the traffic performance of the road for some scenario of the rainstorm impacts on the arterial road, such as water puddle cover one lane, two lane, and three lanes. The analysis results show that the traffic performance become worse during the rainstorm condition. The results provide a basic information for traffic management mitigation when the rainstorm occurred on arterial roads in the city.
