Traffic congestion in Makassar has occurred over the last 3 years due to the increase of\ud
vehicle amount with the lack of adequate road space. To solve the problem, the Intelligent Transportation System (ITS) is needed. One of the research topics in ITS is determining the turnover time of traffic lights based on the number of vehicles in the road. Viola-Jones method can be used to count the number of vehicles by detecting\ud
objects. Therefore, this study shows a simulation of the number of vehicles using the Viola-Jones\ud
method as an initial step to implement the ITS in\ud
Makassar. The data used is a front view car\ud
pictures. Simulation results show that the average\ud
accuracy rate of the detection is determined by the\ud
number of samples. For example, the average of the\ud
highest detection accuracy is 92% by using 150\ud
positive samples and 300 negative samples were\ud
applied to 30 test samples
