Traffic Analysis and Design of Al Ain Downtown Area Civil Engineering Group: Naji Al Mansoori 199900154 Tariq Al Mansoori 199900174 Salman Al Shaqfah 980711488 Ahmed Assaf 199905275 Mohamed Al Natoor 199905240 Suhail Al Neyadi 980710008 Graduation Project 2
Introduction • Roundabout to actuated intersection. • Roundabout to interchange. • Change phases and times. • Interchange to intersection (actuated) • Change speed regulations. • Corridor into intersection.
Base Case 2 1 3 6 5 Speed = 50 (MPH) will be changed to 40 and 60 (MPH) 4
Changing Helton interchange to roundabout by using TSIS program Alternative (4)
The effect on the networkDelay time: • BEFOR • DELAY TIME = 628.96 veh / hr • AFTER • DELAY TIME = 572.75 veh / hr
Alternative (5) Base case: The speed is 50 MPH. Fuel Consumption. Vehicle Emissions (HC). Vehicle Emissions (CO). Vehicle Emissions (NO).
Fuel Consumption A study for changing speed limits from 50 to 40 MPH
Conclusion • Study the output results for the intersection before and after redesign. • Main concepts in comparing the results: • total travel time. • Delay time. • Safety issues. • Environmental issues.
Conclusion • Some of the alternatives were good and some of them were bad according to the issues. • The simulation soft wares save a lot of money when they are used to design the intersections before construction stage.
Thank You • Any questions ??????????????? TSIS
