The objective of this study is to understand the driver behaviour in a signalized intersection in Bekasi, a city in Indonesia. This paper provides characteristics of traffic rule violation in a very busy signalized intersection. Additionally an analysis of traffic conflict in the same intersection is provided. The traffic conflict is the combined effect of both traffic rule violation and opposed signal phasing. The data collection was conducted for about 2 hours in each observation period, i.e. morning peak, mid day off peak and afternoon peak in a normal working day. The selected intersection is located at the heart of Central Business District in Bekasi. Types of observed vehicles were light vehicle, heavy vehicle and motorcycle. The observed traffic rule violation includes vehicle waiting for green beyond stop line, conducting left or right turn without turning on the turn signal, conducting left or right turn in incorrect lane and red light running. The observation was carried out by counting the occurence of each type of violation for each type of motorized vehicle per approach per signal cycle. For traffic conflict analysis, every conflict that potentially causing an accident was recorded. The observation include distance to potential accident, speed, type of conflict, type of movement and type of driver reaction. The % of occurance of different type of violation was affected by type of vehicle. Right turn conflicts (between straight through and right turn vehicle) were dominant. All pairs of driver/ rider reactions involved slowing down. The findings suggest that safety awareness campaign is required to improve driver behaviour in signalized intersection especially regarding conducting right turn/ left turn movement without turning on the sign. In such a busy intersection, opposed signal phasing should not be used as this will potentially lead to dangerous conflicts between straight through and righ turn vehicles.
