MRIGlobal Models Improvements in Traffic Operations

MRIGlobal conducts traffic operational evaluations for two-lane and multilane highways, intersections, and freeway interchanges, and has developed computer simulation models for evaluating improvements to reduce traffic congestion on two-lane highways.

 Our Capabilities:

  • Computer simulation modeling to evaluate traffic operational effectiveness of highway improvements
  • Software development, including database design, analytics, application development and management
  • Policy development
  • Traffic operations research in:
    • Two-lane and multilane highway operations
    • At-grade intersection operations
    • Freeway interchange operations
    • Speed limits and speed enforcement
    • Vehicle performance on steep grades
    • Passing lanes on two-lane highways
    • Turnouts on two-lane highways
    • Shoulder use by slower vehicles
    • Left- and right-turn lanes
    • Two-way left-turn lanes

 MRIGlobal’s Traffic Operations Successes:

  • Two-lane highway operations: For the Highway Capacity Manual, MRIGlobal wrote the chapter on two-lane highways and played a key role in developing the chapter on rural and suburban multilane highways.

  • Computer simulation models: MRIGlobal developed major portions of TWOPAS, the state-of-the-art computer simulation model of two-lane highway operations, and MRIGlobal has used the model in evaluating potential improvements to two-lane highways.

  • Guides and manuals: MRIGlobal developed the Federal Highway Administration (FHWA) guide on Low-Cost Methods for Improving Traffic Operations on Two-Lane Highways.

  • International expertise: MRIGlobal engineers have assessed European 2+1 roadway designs for application in the U.S.
