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.
