**Sub-problem 1a: Analysis of the existing TWSC intersection**

*Step 1. Setup*

The analysis of transportation facilities can be complex,
requiring both the skilled use of standard computational procedures such as the
HCM as well as good judgment in the use and interpretation of results from the
computational procedures. In the setup of this problem, we will consider
the data, the issues, and the tools that are relevant to this problem. In
particular, we will consider the analysis of the U.S. 95/Styner-Lauder Avenue
intersection under two-way stop-control.

Here are some issues to consider as you proceed with the
analysis of the existing intersection and its performance:
