Sub-problem 3d: Collector/Distributor Road

Step 1. Setup

This sub-problem deals with the short, single-lane collector/distributor road that connects to two ramps: the I-787 southbound to Route 7 eastbound loop ramp at its end and the Route 7 eastbound to I-787 northbound loop ramp at its beginning. With the exception of the AM peak hour, the volumes on these facilities are not large. So the focus of this sub-problem is not on the high volumes or congested conditions but on the complexities of performing the analysis. The collector-distributor doesn’t fit any standard facility type, yet it needs to be analyzed. We can use it to give you some ideas about how such facilities can be studied.

Discussion:
Consider how you might analyze this collector/distributor roadway using the methodologies presented in the HCM 2000. When you are ready, click continue to proceed.
