Pontiac Trail Rd. / MI Hwy. 5

Commerce Charter Township, MI


The Road Commission for Oakland County needed a solution to improve safety, access and traffic flow at this busy intersection, and MTJ was retained to provide roundabout peer review services.


MTJ conducted an operational analysis and developed the optimized/corrective horizontal redesign for this constrained intersection. Improvements included:

  • Driver messaging and information processing
  • Speed control – to effect driver behavior and influence slower speeds


  • Improved information processing with signing and pavement marking changes
  • Design modifications to facilitate slower speeds at entries
  • Laneage modifications to improve safety for turn lanes
