Modeling Freeway Work Zones With Mesoscopic Dynamic Traffic Simulator: Validation, Gaps, and Guidance
This study developed a validation procedure for a dynamic traffic assignment—based mesoscopic simulator and identified its relevant data requirements. Model inconsistencies at the network level can be … [Read more...] about Modeling Freeway Work Zones With Mesoscopic Dynamic Traffic Simulator: Validation, Gaps, and Guidance
Data-Driven Traffic Impact Assessment Tool for Work Zones
Traditionally, traffic impacts of work zones have been assessed using planning software such as Quick Zone, custom spreadsheets, and others. These software programs generate delay, queuing, and other … [Read more...] about Data-Driven Traffic Impact Assessment Tool for Work Zones
Lane Bias Issues in Work Zone Travel Time Measurement and Reporting
Work zones are a major source of nonrecurrent congestion. Because travel time is harder to predict in nonrecurrent congestion, accurately measured real-time information on travel time in and around … [Read more...] about Lane Bias Issues in Work Zone Travel Time Measurement and Reporting
Using Private Sector Travel Time Data for Project-Level Work Zone Mobility Performance Measurement
The Federal Highway Administration (FHWA) has been encouraging states to better monitor and track work zone operational performance. The use of mobility performance measures will enable agencies to … [Read more...] about Using Private Sector Travel Time Data for Project-Level Work Zone Mobility Performance Measurement
Work Zone Corridor Management in Michigan
Through their "One Corridor Focus" initiative, the Michigan Department of Transportation (MDOT) manages work zones along key corridors as a single unit rather than discrete projects, enabling MDOT to … [Read more...] about Work Zone Corridor Management in Michigan
