CONCLUSION
Based on the data collected for 1 hour intersection signalized traffic observation at
Perwira Residential College intersection, the following conclusion can be summarized in
the following table below:
Phase I II III IV
Movement PTL1 PT2 BTL1 BT2 PR3 BRU3 HTLR1 PRTLR1
W (m) 3.25 3.0 3.0 3.0 3.0 3.0 3.0 3.0

Class 1 (Motorcycles) 264 0.33 87.12
Class 2 (Car) 487 1.00 487.00
Class 3 (Vans & Medium Trucks) 55 1.75 96.25
Class 4 (Heavy Trucks & Buses) 85 2.25 191.25
Total (BTL1) 891 861.62
a) Level of service in each lane at every intersection consist mostly at F level.
b) During the peak hour, we can concluded that Batu Pahat approach - through, left turn
at Lane 1 consists the highest level of flow which is 861.62 pcu/hr. This is due the
highest number of traffic volume which is 891 veh/hr.
c) Recommendation had been suggested to improve traffic flow, which are:
- traffic signalization
- lane configuration
