Speed Analysis along Ipoh-Lumut Highway

Speed is an important transportation consideration because it relates to safety, time, comfort,
convenience and economics. Due to development of lpoh-Lumut Corridor, the need to
address the growing traffic volume and safety on lpoh-Lumut Highway arises. Speed is also
related to Level of Service (LOS) characteristic of a particular highway. This study aims to
assess the general roadway speed on lpoh-Lumut Highway and to propose new set of speed
limit. lpoh-Lumut Highway is being demarcated by normal car odometer during a trial run
from Ipoh to Lumut. Spot speed studies will be conducted in stretches demarcated. Based on
the similar study conducted in United States of America, speed data collected will be used to
set a speed zone along Ipoh-Lumut Highway. Literatures have supported that using 85th
percentile speed to set an appropriate speed limit will result in a reduction in crashes and an
increase in Level of Service.
