This paper present conducted study to determine the traffic capacity of signalized intersection, level of service signalized intersection and the congestion speed occur at study location. This study is focused at the area of UTHM main entrance and the signalized intersection located near to the main entrance. Congestion problems are closely related to the main entrance area because at this area there was a bottleneck phenomenon which can cause traffic congestion. Base on observation that has been conducted, traffic congestion occurs at peak hour which was vehicles through the area with the maximum amount. In this study, the peak hour for data collection was selected in the morning and evening peak. Video recording has been used to collect data at the study location. Level of Service for traffic lights obtained using the Highway Capacity Manual (HCM). Data observations have been made within a week to identify the day that has the highest traffic capacity. The analysis indicated that Tuesday recorded the highest traffic capacity with 374 vehicles per hour in the morning and 472 vehicles per hour in the afternoon. The level of service for the signalized intersection obtained from the analysis was at the level D during the morning peak and level E during afternoon peak. The movement of traffic congestion obtained at the exit lane was moving backward with a speed of -0.8km/hr and -0.2km/hr. At the entrance, movement of traffic congestion obtained was moving forward with a speed of 12.17 km / hr. From the analysis, we found that congestion occurs is critical to the exit from the entrance. Overall, it is found that congestion occurs at the exit lane is more critical than the entrance
