The document discusses optimizing traffic flow at the UKM intersection in Bangi, Malaysia using the SIDRA Intersection software. It involves collecting input data on traffic volumes, developing a base model of the existing intersection, and then performing four modifications in simulations to analyze impacts on delays, costs, fuel consumption and CO2 emissions: 1) Optimizing the cycle time from 164 to 150 seconds, 2) Changing from a four phase to two phase signal, 3) Adding slip lanes to all approaches, and 4) Adding an additional lane to each approach and exit. The results show reductions in delays, costs, fuel use and CO2 emissions from the base case with each subsequent modification.

- 1. OPTIMIZATION OF TRAFFIC FLOW BY USING SIDRA INTERSECTION UNDER SUPERVISION OF Prof. Dr. Hj. Amiruddin Ismail Prepared by : HAMZAH ALI P 63147 HOOMAN P ZURINDA BT MAT RABU P
- 3. INTRODUCTION Allow the change of route directions of traffic flows. Traffic control systems are capable to An area which reduce delays shared by two and crashes on or more roads. INTERSECTION intersection Problem of delay still occurs
- 5. SIDRA • Estimate of capacity and performance characteristics • Analyze and optimize the intersections • Determine signal timing • Carry out a design life analyze for traffic growth
- 7. Advantages of using sidra Use the parameter sensitivity Use a lane-by-lane analysis method Consistent with the US Highway capacity manual Provide a Excel application to support model comparison Estimate operation cost , fuel consumption , co2 & other emission
- 8. Study objective • The main objective of the Study is to prepare low cost solutions to an existing intersection
- 9. Study area • The intersection is located in front of the main entrance of UKM. • North side :Toll Bangi/Bandar Baru Bangi • South side : UKM • West side come from Bangi and will end to Kajang at East .
- 10. N To Kajang To Bangi
- 11. Data's 8-9 am & 6 – 7 pm • Duration 15min => extended to 1hour • Considerations : Vehicle types, direction, speed (to gain mean speed)
