Many factors contribute to road accidents on a
particular road. Jalan Batu Pahat-Kluang (FT 050) is
the main road connecting two major towns in Johor,
namely Batu Pahat and Kluang. It is a four-lane
undivided highway which has a total average daily
traffic (ADT) of over 25,000 veh/day. According to
statistical data obtained from the PDRM Batu Pahat
traffic branch, there were a total of 4,963 accidents
happened during the period of 2002-2006 along Jalan
Batu Pahat-Kluang (FT 050). This caused 160
fatalities and 1,027 injuries. A study relating flow rate
and free flow speed to accident frequency was done
and results show that flow rate has a strong positive
effect on road accidents along Jalan Batu Pahat-
Kluang (FT 050) while free flow speed relates to
accident indirectly as an effect of flow rate.
