Pershing Blvd./Converse Ave./19th St.

Cheyenne, WY

BACKGROUND

The City of Cheyenne retained MTJ to provide an in-service design review and provide recommendations aimed at improving driver comprehension and reducing the number of vehicular crashes occurring at this roundabout.

REVIEW PROCESS FRAMEWORK

The MTJ in-service design review focused on three key areas:

  • Driver messaging and information processing
  • Speed environment – to effect driver behavior and influence a slower speeds
  • Rodel operational analysis to identify potential conflict point reductions

 
MTJ provided a range of recommendations from lower cost, signs and markings, to relatively higher cost implementations to include slight geometric modifications.

The MTJ crash mitigation recommendations build upon one another in a comprehensive manner.

RECOMMENDATION HIGHLIGHTS
 

  • Improved information processing with signing and pavement marking changes
  • Design modifications to facilitate slower speeds at entries
  • Recommended lineage modifications to reduce conflict points
