Sub-problem 1b: Analysis of the Signalized Intersection with Projected Traffic
Step 1. Setup
With projected traffic levels, the TWSC intersection has substantial delays and queues. In this sub-problem, we will investigate the possibility of signalizing the intersection to determine if that would improve the situation. As noted previously, this is an operational look at signalizing the intersection. A signal warrant analysis using the procedures defined in the MUTCD would normally be necessary to pursue this option.
Here are some issues to consider as you proceed with the analysis of the existing intersection and its performance.
-
What data is needed for this analysis?
-
How can you compare the delay at an unsignalized intersection and a signal?
Discussion:
Consider
the factors listed above. Each of these factors has been discussed in
previous Case Studies within the HCMAG. How would you obtain the required
data for each of these factors to analyze the operations of a signalized
intersection? Take a few minutes to consider these factors. Click continue
