Speed Hump Model: A Case Study in Malaysia Residential Streets
Authors: , , , ,
Abstract: Speeding and speed control are often considered critical issues on residential and collector streets. In addition, speeding complaints are a continuing problem for traffic engineers and police department. Supporting the idea of controlling speeds is the assumption that reducing speeds also reduces accidents. However, different speed limits require different speed hump profile. In Malaysia, speed hump design varies widely between road authorities, some of the dimensions designed by the local authorities been implemented on an ‘ad hoc’ basis without any proper standards or guidelines [1]. With many styles and inconsistencies, a study to develop an optimal speed hump geometric design was needed considering the observed 85th percentile speed and speed hump geometric design at 76 implemented speed hump location. After several analyses were conducted one model with R-Sq value of 80.6% was developed using multiple linear regressions. The model was further validated using about one third of a new data set from the overall data used in the model development. It was found that the model was reliable which produce small discrepancies when compared between the empirical and predicted results. Hence, the models can be accepted and considered reasonable for the purpose of this study.
