Module 7 Exercise Intersection & Interchange Geometrics (IIG) Innovative Design Considerations for All Users
APPLICATION EXERCISE In teams, participants will discuss potential applications of alternative designs at the following three intersections: 1.US 151 - Rural expressway 2.SR 7 - Arterial in developing suburb 3.US 167 - Urban arterial
US 151 SCENARIO 1 RURAL FOUR LANE DIVIDED HIGHWAY
US-151 & Springville Rd.
FAR SIDE ANGLE COLLISIONS
SR 7 SCENARIO 2 SUBURBAN HIGH VOLUME ARTERIAL
SR 7 at Berry Hill Road
CONTEXT AND CONDITIONS Rapidly developing suburban land use Commercial on north side Residential / mixed-use on south side Currently STOP control at both minor road approaches Heavy through volumes on arterial 45 mph posted speed – higher operating speeds Residents and businesses are complaining about delay waiting to turn out from minor roads – they want a signal!
