Proposing new speed hump signs and evaluating their effectivenesss in Asian countries

Abstract

Speeding is the vitally important traffic problem as it is one of the most-reported factors associated with crashes. Traffic calming is an ideal solution, especially the hump. But, in some places, over-speed at the hump is happening on roads. To lessen the speed, using hump signs can offer net positive benefits as they would be a practical and the most cost-effective method. However, Asian countries do not have a standard manual for hump signs, therefore, this study designs new hump signs and assesses their effectiveness. Total of 172 respondents in some Asian countries were involved in this research by answering online questionnaire after watching 3D videos. This research found that with the presence of hump signs, they affected positively on the feeling of respondents about the minor road, so drivers would think to drive carefully, slowly, and give priority to pedestrians on the minor road.
