Speed Change Distribution of Vehicles in a Highway Work Zone
In response to roadway geometry and traffic control devices, motorists may change their speeds within a work zone. Speed profile data for 102 automobiles (cars and vans) and 49 trucks, which traveled … [Read more...] about Speed Change Distribution of Vehicles in a Highway Work Zone
Speed Variations Are Major Cause of Work Zone Crashes
Rear-end collisions cause the preponderance of work zone crashes in Virginia, indicating that a high variance in vehicle speeds is the major cause of accidents in work zones, according to a … [Read more...] about Speed Variations Are Major Cause of Work Zone Crashes
An Artificial Neural Network Speed Profile Model for High-Speed Highway Construction Work Zones
Speed profile models can be used by highway engineers to assess the adequacy of a design. Previous work has investigated relationships between operating speed and geometric roadway elements for … [Read more...] about An Artificial Neural Network Speed Profile Model for High-Speed Highway Construction Work Zones
Artificial Neural Network Speed Profile Model for Construction Work Zones on High-Speed Highways
Speed profile models can be used as a diagnostic tool by highway engineers. Previous work has investigated relationships between operating speed and geometric roadway elements for permanent roadway … [Read more...] about Artificial Neural Network Speed Profile Model for Construction Work Zones on High-Speed Highways
Lighted Guidance Devices: Intelligent Work Zone Traffic Control
Annually, thousands of highway workers risk serious injury and death from drivers who enter work zones too fast or accelerate after entering the zone and then, because of their excess speed relative … [Read more...] about Lighted Guidance Devices: Intelligent Work Zone Traffic Control
