Abstract

To reduce potential pedestrian fatalities, in residential road maximum speed is 30km/hour. Apart from installing maximum speed signs, installing road humps may ensure speed reduction. This paper is intended to compare light vehicles and motorcycles speeds and speeds reductions due to road humps. Data collection was done in Modernland, Tanggerang City. Two road segments were observed, i.e. segments with standard and non-standard road humps. Observation was made in morning, noon and afternoon periods. A portable speed gun was used to measure the speed at about 50m and 25m before the road humps. Some mean difference statistical analyses were conducted for both speeds and speeds differences between different type of road humps and between pairs of observation periods. The 0.05 significant level was used. Surprisingly, mean of speeds differences (50m vs 25m) in standard road hump is significantly higher than in non-standard road hump.

Highlights

In residential roads, there are many daily domestic activities, such as, children crosing the roads to reach or return from school, senior citizens walking in the road to get fresh air in the morning, housewives crossing the roads to reach or return from grocery shops etc
As the speeds 25m before both type of road humps were about the same the speeds reductions before standard road hump were higher than speed reductions before the nonstandard road hump for both light vehicles and motorcycles
It should be noted that all mean speeds at 50m before any types of road hump were higher than 30 km/hours

Summary

Introduction

There are many daily domestic activities, such as, children crosing the roads to reach or return from school, senior citizens walking in the road (where pedestrian path is not available) to get fresh air in the morning, housewives crossing the roads to reach or return from grocery shops etc. To reduce potential pedestrian fatalities due to crash between motorized vehicles, in residential road maximum allowable speed is 30km/hour. Apart from installing maximum speed signs, installing road humps may ensure speed reduction. This paper is intended to compare light vehicles and motorcycles speeds and speeds reductions due to road humps. Data collection was done in Modernland, Tanggerang City. Two road segments were observed, i.e. segments with standard and non-standard road humps
