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.
