| Summary: | As a traffic calming measure, the installation of road humps in residential areas has helped reduce the
speeds of vehicles along residential roads. However, it is also widely seen that changes in speed
regarding sudden deceleration and acceleration near the road humps have increased the noise level of
the traffic in the residential areas. This paper discusses the effects of road humps, as a traffic calming
measure, on the traffic speed and noise levels in a residential area. The study was conducted for two
different sets of road humps in Putrajaya, Malaysia. The speeds of moving vehicles and noise levels
were measured for a 12-hour period using radar guns and noise level meters at selected points. The
sample size was determined using the systematic sampling technique based on the 12-hour traffic
volume count conducted beforehand. The relationship between speed and noise levels at road humps
are assessed together with the respective road and hump characteristics, with the finding that the
impacts on noise levels were influenced by the rate of speed reductions, which is dependent on the
road hump and road geometrics. Road humps were also found to not necessarily contribute to
reduction in noise levels despite being effective in reducing vehicle speeds. |
