Estimation of Relationships Between 85th-Percentile Speed, Standard Deviation of Speed, Roadway and Roadside Geometry, and Traffic Control in Freeway Work Zones
Understanding speed behavior in construction work zones is critical to making appropriate geometric design, roadside design and traffic control decisions. Gaps exist in national work zone design … [Read more...] about Estimation of Relationships Between 85th-Percentile Speed, Standard Deviation of Speed, Roadway and Roadside Geometry, and Traffic Control in Freeway Work Zones
Field Evaluation of Variable Advisory Speed Limit System for Reducing Traffic Conflicts at Work Zones
A practical methodology to reduce the traffic conflicts at work zones was developed and evaluated in the field. The proposed system uses variable advisory speed limits that are determined with a … [Read more...] about Field Evaluation of Variable Advisory Speed Limit System for Reducing Traffic Conflicts at Work Zones
