MRIGlobal Research, Analytics Bring Safer Trucking Operations
MRIGlobal has performed extensive research on truck operations, including truck rollover thresholds, performance of single- and double-trailer trucks, hazardous materials transport, and the role of tires in safety.
This work has recommended operational guidelines and influenced geometric design and traffic control policies.
- Analysis of high- and low-speed offtracking in turns
- Truck rollover threshold determinations
- Model for predicting truck speed profiles on steep upgrades and downgrades
- Performance analysis of single- and double-trailer trucks and longer combination vehicles (LCVs)
- Passenger-car equivalents of trucks for operational evaluations
- Geometric design requirements for trucks
- Hazardous materials transportation safety guidelines
- Analysis of the role of truck tires in safety
- Truck considerations in work-zone design
MRIGlobal’s Truck Operations and Safety Successes:
- Design evaluations: MRIGlobal evaluated the extent of geometric design improvements needed for selected truck networks to accommodate current and potential larger trucks. This research supported the Federal Highway Administration (FHWA)’s Comprehensive Truck Size and Weight Study.
- Computer simulations: MRIGlobal modeled truck performance on upgrades in TWOPAS, the state-of-the-art computer simulation model of two-lane highway operations.
- Reports and Synthesis: MRIGlobal prepared Report 505, Review of Truck Characteristics as Factors in Roadway Design, for the National Cooperative Highway Research Program. MRIGlobal prepared a synthesis on highway/heavy vehicle interaction for the Commercial Truck and Bus Safety Synthesis Program.
Engineer Contributes to MRIGlobal’s Legacy in Traffic Safety Guidelines
MRIGlobal’s traffic engineers have been responsible for key portions of America’s traffic safety policies and guidelines, including the Transportation Research Board’s Highway Capacity Manual, the Federal Highway Administration’s Manual on Uniform Traffic Control Devices, and the AASHTO Policy on Geometric Design for Highways and Streets.
