3. Introduction Project Objectives Congestion Management Process Selected Strategies Signal Timing Optimization Bus Lane Priority Improvement Conclusion & Recommendation Skills Learnt

4. Congestion Becoming a daily life style in Abu Dhabi • Congestion occurs when traffic demand exceeds the capacity Relieve the Traffic Congestion

5. Project Objective • Identify the causes of traffic congestion in Abu Dhabi metropolitan region • Design a structure for traffic congestion management process (Done in GP I) • Evaluate different traffic congestion management techniques & strategies for the region (GP II)

6. Congestion Management Process • Congestion Management Process (CMP) is a systematic process for defining: • Acceptable levels of congestion to community • Developing performance measures • Developing alternative strategies to manage congestion • Implement the strategies and evaluate them

7. Our Selected Strategies • Signal Optimization Strategy • Bus Lane Priority Strategy

8. Signal Optimization $ Congestion Management Technique Evaluation Of different alternatives Maximum Output Minimum Delay

26. Benefit from using Bus Lane Strategy Buss Lane Priority   Bus Services Congestion

27. Cost Estimation

28. Conclusions • Both strategies • Reduce traffic congestion • Improve traffic flow • Reduce Emission • Designed signal timing plans give relatively Maximum Output & Reduce Delay

29. Recommendations • DOT should Evaluate and Implement strategies on other corridors in Abu Dhabi • For Safety issues, DOT should educate Drivers’ related to Signal Phasing and other changes

30. Skills Learned • Traffic operational softwares; Synchro & Simtraffic. • Mapping Software “Universal Map” • Design of Signal Timing Plan • Professional Report Writing • Team Work & Project Management • Website Design
