At Universiti Teknologi PETRONAS, speeding is one of the most common traffic offences by the students. A few traffic calming measures such as road humps and raised crosswalks were implemented with the purpose to reduce the speeding offence in the university. However, the effectiveness of the implementation is never been studied. This project will evaluate the feasibility of these structures in detail. Data collection was the first step conducted using questionnaires to obtain feedback from the users on the effectiveness of using the existing traffic calming structures. In reconnaissance survey, locations of selected road humps and raised crosswalks were determined. In data gathering process, dimension of the existing structures were measured using recommended method to determine whether the design met the standard specifications. The most important part was determining the speed of the moving vehicles using radar gun. Series of data on speeds of the vehicles were used to construct the speed profiles. The results show that at some of the locations of the study, the traffic calming measures could not effectively reduce the speed of vehicles and exceeded the speed limit of the campus. Therefore, modifications on the design of the structures in terms of dimension are proposed to meet the design specifications. There are also recommendations to introduce other traffic calming structures that are having the potential in reducing the speed of vehicles.
