Problem 2: Reitz Union Drive Intersection Improvement Strategies

We can set up this analysis by using the data from Problem 1 to analyze the actuated signal control of the improved intersection with projected traffic in a standard HCM application using the procedures in Chapter 16 for Signalized Intersections. The operational analysis of a signalized intersection under actuated control requires the following typical data:

• peak-hour turning movement volumes and peak-hour factors

• pedestrian and bicycle flow rates

• pedestrian walking speed, travel distance, and crosswalk width

• lane numbers, widths, and usage

• queue spacing and storage signal phasing, timing, and clearance data

• number of approach grades, heavy vehicles, parking, and bus stop influence

The critical data for this analysis are shown in the following table:
