CE474 Traffic Systems Design - Fall 04

Design Project 1-General Project Description:

Design fixed-time control optimal control plans for the intersection using 2008 volumes for one of the following intersections:

Project Requirements:

1. Design report 1 is due at the beginning of class on September 14th

2. You will be responsible for developing optimal signal timing plans for the intersection given a set of future (projected) traffic volumes for the year 2008. 

3. All approaches operate “C” or Better

4. You should conduct your analysis of the design alternatives using the Highway Capacity Software and the CORSIM simulation model.

5. Average control delay per vehicle, volume/capacity ratio, and queue length should be used as your measures of effectiveness in optimizing your design.

6. You may consider changes to lane configuration or alignment as long as your design remains within the existing curb-to-curb right of way.

7. The signal timing design will include the following parameters: (1) phasing plan, (2) cycle length, (3) green splits, (4) pedestrian phase lengths, (5) yellow time, (6) all-red time.

8. You should define a set of phasing plans and a range of timing parameters that are appropriate to be considered as alternatives for your intersection. 

9.  The project report must be no longer than 20 pages, including all text, figures, and tables.

10. The project report should clearly describe the design alternatives that you considered (the range of values that you considered for each parameter), the results of the analysis of the alternatives, your final design parameters, and why you selected your final design parameters. 

11. The report should also include all supporting information including figures, tables, and computations.
