Infuence of speed and flow rate on road accidents: a case study along federal route 50 (FT 050)
Federal Route 50 (FT 050) has an annual average daily traffic (AADT) of more than 68,000 vehicles daily at the Batu Pahat-Parit Raja stretch and above 22,000 vehicles daily at the Ayer Hitam-Parit Raja stretch in 2010. During peak hours, the traffic volume could even go beyond 9,000 veh/hr at...

| Summary: | Federal Route 50 (FT 050) has an annual average daily traffic (AADT) of more than
68,000 vehicles daily at the Batu Pahat-Parit Raja stretch and above 22,000 vehicles
daily at the Ayer Hitam-Parit Raja stretch in 2010. During peak hours, the traffic
volume could even go beyond 9,000 veh/hr at certain sections. Works Ministry of
Malaysia (KKR) reported that Federal Route 50 (FT 050) had been identified as the
“deadliest stretch of road” in Malaysia. The road recorded more than an average of
1,000 accidents and 36 deaths annually since 2006. This research aims to study the
effects of speed and flow rate on road accidents at selected sections along Federal
Route 50 (FT 050), which each has different road characteristics. Spot speed study
was carried out at KM 5, KM 10, KM 15, KM 20, KM 25 and KM 30 to evaluate the
influence of speed upon road accidents, while traffic volume count was conducted at
KM 5, KM 20 and KM 30 to identify the effect of flow rate upon road accidents.
Besides that, site observation was also conducted at the selected sections, where road
facilities and countermeasures were studied generally. A model produced using
multiple regression analysis technique with backward method shows that road
accident frequency increases with the increase of flow rate. The model estimates that
every 200 pc/hr/lane increases accident frequency by about 9 acc/yr. On the other
hand, speed relates to accident as an effect of flow rate. By categorising the sections
of FT 050 into 3 different zones based on the frequency of road accidents, results
reveal that road accidents frequency increases with speed at different rates. |
