Course Description

179-Interchange Ramp Characteristics - Selection and Design

This course will give the highway/interchange designer information that will aid them in producing a safe and economical interchange design.

The types of mainline ramp terminals are reviewed, so that the most appropriate terminal, for a specific project can be selected. There is also a section on connection ramps and loop ramps. The question, can a two-lane loop ramp replace an expensive connection ramp, is addressed in this course.

Due to economic and environmental constraints, most new or reconstructed interchanges are forced to be designed using minimum criteria. Therefore, also included is a section on the propensity of heavy trucks to rollover on small radius curves. This material is also covered separately in 170-Horizontal Curve Design To Prevent the Rollover of Heavy Trucks.

Only suggestion would be some basic exhibits at the beginning - re: tapered v parallel.

There were a few questions asked on the exam that could have had better and more specific coverage in the text as there wasn't enough specific information given in the text to exactly answer correctly. Left hand exiting from a left had turn needed more specific guidance and speed differential versus accident increase was poorly covered also, versus the test questions. It wasn't 5/5 stars because of those two things, but it was a solid course otherwise. I would give it three out of five stars.

The text did not fully address how to relate lateral acceleration with rollover threshold value. Not all the terms in the equation are defined.
