FOREWORD
This Malaysian Standard was developed by the Working Group on Speed Bump under the authority of the Industry Standards Committee on Building, Construction and Civil Engineering.
Compliance with a Malaysian Standard does not of itself confer immunity from legal obligations.
SPEED BUMP- SPECIFICATION FOR MATERIALS, DESIGN AND
INSTALLATION
1
Scope
This Malaysian standard describes the traffic calming devices that cause a vertical deflection of the vehicle. Vertical shifts in the roadway are the most effective and reliable for speed reduction.
Speed bumps are abrupt humps, normally less than 3 feet (1 meter) in length. The primary function of a speed bump is used for reducing the speed of motor vehicles. The types of speed bumps varies accordingly to the conditions and needs of a given streets as shown in Figure 1 and Figure 2.
2 Terms and definitions
For the purposes of this standard, the terms and definitions given in MS 2236 apply.

Objectives of speed bump’s installation
Objectives of speed bump:a) it is intended to reduce speed;
b) it is intended to reduce the noise level due to the lower speed of vehicles; and c) help in promoting the public’s safety.
4 Advantages and disadvantages of speed bumps
Advantages and disadvantages of speed bumps are tabulates as per Table 1 below:
Table 1. Advantages and disadvantages of speed bumps Advantages Disadvantages
a. effectively reduce the vehicular speed a. speed may increase when the drivers get used to feel of the speed bump
b. to promotes safety of public (pedestrian) b. increased the delay time for emergency vehicle response
c. cheaper and low in maintenance as compared to speed hump
5 Application
Table 2 describes the applicability of speed bump in terms of their characteristics of roadway, traffic condition, location and population.
Table 2. Applicability
Item Description
a. road category Roads within parking lot, check points and service areas including access road
NOTE. Any other installation is subjected to approval of the governing authority b. roadway One through travel lane per direction
Apply on roads without curb
Apply across the entire width of roads surface c. traffic condition Speed limit not more than 25 km/h
It should be built with street lighting to maximize visibility Transverse bars should be installed before speed bump where appropriate i.e on the straight road.
6 Design and specification
The installation or implementation of speed bump must be according to the specification as in Table 3 and design standard as in Figure 3.
