Problem 5: Interstate 87 Interchange

What have we learned from this problem? Maybe the most important thing we’ve learned, in the context of the case study, is that the interchange is adequate with the site-generated traffic, except for the southbound-to-westbound off-ramp and the westbound left onto the southbound on-ramp.

In the context of the HCM procedures, we’ve seen how a variety of methods can be used to explore the performance of specific locations within the interchange. We’ve applied merge and diverge analyses to the major ramp terminals, we’ve done a weaving analysis of the eastbound section of highway between the two loop ramps, and we’ve used the unsignalized intersection analysis methodology to assess the performance of two unsignalized junctions.
