Abstract- Speed is an important transportation consideration because it relates to safety, time, comfort, convenience, and economics. Spot speed studies are used to determine the speed distribution of a traffic stream at a specific location. The data gathered in spot speed studies are used to determine vehicle speed percentiles, which are useful in making many speed-related decisions. The intent of spot speed studies are to record speed characteristics under prevailing traffic conditions at a specific location along a roadway. Because traffic engineering involves the collection and analysis of large amounts of data for performing all types of traffic studies, it follows that Spot Speed Study is also an important element in traffic engineering. Managing traffic within our communities is a growing task for traffic engineers. As traffic volumes increase and public financial resources decrease, targeting improvement projects to anticipate growth patterns is critical. This paper represents traffic condition on the Malaysia Federal Route 5 - Skudai- Pontian Highway.

I. INTRODUCTION
Speed is an important measure of the quality of level and safety of road network. Speed by definition is the rate of movement of vehicle in distance per unit time.
A typical unit of speed is kilometers per hour (kph) or miles per hour (mph). basically there are two types of speed: the time-mean speed and the space- mean speed. Space mean speed is the length of a road section divided by the average travel time of several vehicles over this specific section. The time-mean speed (spot speed) is the average spot speed of several vehicles measured at a given spot.
A. Federal Road Standards
The total length of federal roads in Malaysia is 49,935 km (31,028 miles). Federal routes are labeled with only numbers for example Federal Route 1 while state routes are labeled with the state code letter followed by assigned numbers, for example Route J32 is a Johor state road However, federal route numbers can also be added with the FT- prefix, which is normally used by JKR and Malaysian police. For example Federal Route 1 can also be written as Federal Route FT 1.
Both federal and state roads have blue road signs and the...
