Study On Traffic Conlict At Unsignalized Intersection In Malaysia

Abstract

The research conducted is traffic conflict at unsignalized intersections . The purpose of this research is to study accident data used as an identification of hazardous location leads to less accurate countermeasures. It is because accidents are not always reported especially accident involving damage only and this situation can reduce good comparative analysis. To overcome these lacks of accident data, many ways of employing non- accident data have been suggested. One of the ways using non-accident data is traffic conflicts, which is defined as critical incidents not necessarily involving collisions. The traffic conflict technique was originally set up to provide more reliable data and information of traffic problems at intersections which actually would replace the unclear and incomplete recorded data accident. The conflict study was done at the selected unsignalized intersection where types of traffic conflict can be identified and classified. Various road users involved in the conflict at the unsignalized intersection were also observed. Then conflicts data captured were analyzed using the computer program to observe for any conflicts at the intersections. The linear regression graph was used to show the relationship between conflict and accident data where two different equations were derived from the graph. This equation may be used to make a prediction for the relationship that might exist between those two variables at another location. Index Terms: Traffic conflict and unsignalized intersection
