Abstract

Heterogeneous traffic in urban arterial roads are many developing cities in Makassar city, leads to the high potential of traffic accident occurs in the cities. Regarding the issue, the present study aims to model the traffic accident frequency which occurred in urban arterial roads which case study in Makassar city, Indonesia. This study constructed the model based on microscopic characteristics of the heterogeneous traffic, namely longitudinal distance and lateral distance between two nearby vehicles. The data collection involved two stages. Firstly, the data collection for traffic accident characteristics which occurred in the city and secondly, the traffic characteristics, namely traffic flow in arterial roads of the city. There were three steps in constructing the traffic accident frequency model. The first step applied a micro-traffic simulation in calibrating the microscopic characteristic values. The second developed a relationship model between traffic flow and both microscopic traffic characteristics. The third step constructed the traffic accident frequency model using the longitudinal and lateral distance between two nearby vehicles. The model was acceptable regarding root mean square error test. The model is useful in estimating the traffic accident number in urban arterial roads m developing cities where its traffic characteristic are heterogeneous.
