| Summary: | Vehicles are the important element in transportation system. It is being used for
traveiing on road to fulfill the demand of working, business, vacation, etc. About 1.4%
of registered vehicles getting involved in road crashes in Malaysia. There were found
about 4.9 deaths per 10,000 from registered vehicles in year 2002. Statistical reports
road accident (PDRM) shows that the road accident by type of faults about 15% by
speeding behavior. These statistic lead to the inevitable conclusion that the impact of
road crashes due to speeding behaviour could be fatal and severed injuries.
Therefore, a study on the effects of different posted speed limits to determine the
operating speed and compliance of speed limits was carried out. The sites were
identified and selected that located on PLUS expressway stretch from Kuala Lumpur to
Seremban. The section of locations were in Sg.Besi area with 80 km/h posted speed
limit, Serdang area 90 km/h posted speed limits and Seremban with H 0 km/h posted
speed limits. There were 100 data collected in spot speed study was carried out for each
vehicles classification namely motorcycle, car, taxi, light van and utility, medium lorry,
heavy lorry and bus. The collection of data were taken from 10.00 a.m to 1.00 p.m
within a month and covered for both southbound and northbound direction. The vehicles
that traveling at or below posted or commercial speed limits was classified as complied
with the speed limits, those who traveling above posted or commercial speed limits at all
was classified as not complied with the speed limits. The data were analysed using
statistical anaysis on univariate and bivariate analysis.
iv
Results from univariate analysis on descriptive frequency showed that the 85"* percentile
speed of car, taxi and bus almost over with the speed limits compared with motorcycle,
light van and utility, medium and heavy lorry. Also the percentage of non-compliance
with speed limits for car, taxi and bus were higher than motorcycle, light van and utility,
medium and heavy lorry. While, from bivariate analysis the results shows eight variables
were significantly associated with compliance of speed limits. They were vehicle
classification, travel direction, different posted speed limits, 110 km/h posted speed
limits, 90 km/h posted speed limits, 80 km/h posted speed limits, car versus taxi and
private vehicle versus commercial vehicle.
Therefore, road safety program should be focused on car at any posted speed limits, taxi
at 90 km/h posted speed limits, bus at 110 km/h posted speed limits, direction of
travelling toward CBD area and speed limits on 90 km/h. It is recommended that future
engineering and non-engineering road safety programs in promoting the anti-speeding
behavior through educating the public to travel with safe speed regarding with speed
limit. Besides, there should be to carry out speed trapped and patrol operation on target
group by the authority. Also, there is need some warn nf a nrwihte withdrawal the
license permit upon any commercial vehicle those are frequently involved in violation of
speed limit. Last but not least, by enforcing on commercial vehicles to install with
special devices on speed pedal to restricted form speeding over speed limits. |
