3D Visual Effect Speed Hump for Urban Road

Abstract

The speed limit allowed in educational institutions is 30 km/hour and only speed humps are allocated at Politeknik Sultan Haji Ahmad Shah (POLISAS) roadways. Speed hump are well known for roadways in Malaysia, but the effectiveness of 3D visual speed hump is still new and not well explored. The purpose of this study is to design the 3D visual effect speed hump and to evaluate respondents’ perceptions towards the development of 3D visual effect speed hump. Spot Speed Study was carried out using radar gun to determine the effectiveness of 3D visual effect speed hump implementation. Survey method using questionnaires were distributed among students, lecturers and road users to evaluate respondents’ perceptions. The test was conducted to analyse the speed limit data before and after installation of 3D visual speed hump. The results showed that the speed of the vehicle before the installation is 43 km/h and decreased to 30 km/h after the installation of 3D visual effect speed hump. The survey also proved that the respondents’ perceptions for driver’s behaviour (41%) is crucial. Therefore, the study confirmed that 3D visual effect speed hump is effective to be implemented in reducing the approaching speed of vehicle.
