Assignment -
Transportation - Development was typically approved one project at a time with little consideration to cumulative impacts in form of deterioration of levels of service (LOS) on roadways and increasing delays
Procedure -
- Determine if proposed development can be accommodated within the existing or planned transportation system.
- Identify improvements beyond those already anticipated that can accommodate the proposed development.
- Determine how developments of significant size can occur so as not to adversely affect traffic operations or safety near the site.
- Identify intersections that might be affected
- Identify is the level of service will be degrades - longer times between lights, longer delays, etc
- Create a simulation of the traffic and intersections
- Add future expected demands
- Add development demands
- Determine impacts
- Create scenarios to minimize impacts
- Design useful improvements to improve traffic flow and reduce delays
Develop the Following to Analyze
- Select aerial photographs to initiate the drawing. It is very important to accurately measure the width and length of the images to prevent errors.
- Import data to the software package and after the pictures are properly scaled, the legs and the sections are created.
- The turning lanes are added in the appropriate directions from southbound, northbound, westbound, and eastbound.
- Incorp signals based to their orientation directions.
- The signal timing is calibrated in the master control plan.
- Using traffic data obtained from the local traffic agency, the access points percentages and the number of cars are determined.
- Key times of concern (typically rush hour) are identified for the worst case scenario analysis.
- Vehicles including trucks, pedestrians, bicycles, buses, and trains, as applicable are added to the model.
Then Simulate and adjust to optimize improvements.
