Subproblem 1a:
Analysis of the
Existing TWSC Intersection
Step 1. Setup
In consideration of
this analysis, we must first recall the importance of this facility as a
multimodal corridor. The presence of pedestrians on this corridor will
present some challenges for our analysis. In this problem, we will also
interpret results from the HCM methodology, translating results that are
mere mathematical equations to more meaningful results to present to the stakeholders involved in the project. Here
are some issues to consider as you proceed with the analysis of the existing
intersection and its performance.

What is the data that is needed for this analysis?


What is the level of service of this unsignalized
intersection today? In the future?


How might you interpret the estimates of delay at an
unsignalized intersection to acknowledge the limitation of the methodology?


What is the effect of pedestrians on the intersection?

Discussion:
