Title: The use of rumble strips as a speed - reducing measure on the Kasoa – Winneba road
Authors: Fordjour, Patrick
Issue Date: 3-Nov-2016
Abstract: The installation of rumble strips on the Kasoa-Winneba road is aimed at reducing speed, especially within settlements along the road to improve traffic safety. Thus, this research attempted to determine the effectiveness of the installation of rumble strips as a speed reducing measure. An inventory of rumble strips was conducted and spot speed data were recorded on sections with rumble strips and sections without the rumble strips. Speeds were recorded for all the classified vehicle types. The analysis of the spot speed data indicated that vehicles reduce speed at sections with rumble strips. Again the percentage of speed reduction at locations where strips were preceded by speed humps was significant compared to locations without speed humps. It was also revealed that small vehicles recorded the least reduction in speed of 23%, followed by medium vehicle represented by minibus with 28% reduction in speed. Heavy vehicle represented by a heavy truck recorded the highest speed reduction of 33% in speed .The overall speed reduction for all the three categories of vehicles was estimated as 26%. Considering the percentage reduction in speeds for categories of vehicles, it can be concluded that, the installation of rumble strips is an effective speed reducing measure in the light of pedestrians’ fatalities especially within settlements on highways.
