Problem 1: U.S. 95/Styner-Lauder Avenue Intersection

Printable Version Printable Version

We will begin our work by considering the operations of the intersection of U.S. 95/Styner-Lauder Avenue under two kinds of control, the existing stop-sign control and the proposed signal control. In problem 1, we will focus our attention only on this intersection, without consideration of the effects of the adjacent intersections. This approach will allow us to develop an initial assessment of whether stop-sign control is better than signalized control, but we must keep in mind that other factors (including, for example, the proximity of adjacent intersections and the manner in which they are controlled) can also have a very big influence on our final recommendation. These effects will be considered later in Problem 2.

For this particular analysis, we must first complete two computations for the existing traffic volume conditions. Then, we will consider the projected future volumes. We can pose three questions that will guide the computations:

bullet

What is the level of service at the existing TWSC intersection at U.S. 95/Styner-Lauder?

bullet

What would the level of service be if the intersection were signal controlled?

bullet

What would the level of service be at the intersection under future projected traffic conditions?

Discussion:
Take a few minutes to consider these questions. When you are ready, click continue below to proceed.
