Devices to Implement Short-Term Speed Limits in Texas Work Zones
In Texas, speed limits for short-term (less than 12 consecutive h) work zones are used when workers or equipment are not behind a concrete barrier, work activity is within 15 ft of the pavement edge, … [Read more...] about Devices to Implement Short-Term Speed Limits in Texas Work Zones
Closed-Course Test and Analysis of Vibration and Sound Generated by Temporary Rumble Strips for Short-Term Work Zones
Driver distraction and speeding are two contributors to crashes in construction and maintenance work zones. Rumble strips can be effective and have been used in some states to alert drivers to reduce … [Read more...] about Closed-Course Test and Analysis of Vibration and Sound Generated by Temporary Rumble Strips for Short-Term Work Zones
Two Simplified Dynamic Lane Merging System (SDLMS) for Short Term Work Zones
ITS-based lane management technologies were introduced to work zones in an attempt to reduce congestions and diminish queue lengths. Two forms of lane merging namely the early merge and the late merge … [Read more...] about Two Simplified Dynamic Lane Merging System (SDLMS) for Short Term Work Zones
Development of a Methodology to Estimate the Interstate Highway Capacity for Short-Term Work Zone Lane Closures
Defining and understanding traffic flow parameters within short-term interstate work zones is a crucial step in developing effective policies to manage construction and maintenance work conducted on … [Read more...] about Development of a Methodology to Estimate the Interstate Highway Capacity for Short-Term Work Zone Lane Closures
