A Simulation Study of Passing Drivers’ Responses to the Automated Truck-Mounted Attenuator System in Road Maintenance
The Autonomous Truck-Mounted Attenuator (ATMA) system is a lead-follower vehicle system based on autonomous driving and connected vehicle technologies. The lead truck performs maintenance tasks on the … [Read more...] about A Simulation Study of Passing Drivers’ Responses to the Automated Truck-Mounted Attenuator System in Road Maintenance
Speed Variation and Safety in Work Zones
In addition to lower speeds, the difference between vehicle speed and the average speed on the roadway has been identified as a factor in roadway crashes. For work zones, the potential for such speed … [Read more...] about Speed Variation and Safety in Work Zones
Mobile and Slow-Moving Operation at Work Zones for Aging Transportation Infrastructure Maintenance
Infrastructure maintenance is very important to the efficiency of our transportation system. In 2020 alone, USDOT spent a total of $24 Billion dollars to preserve national highway systems. In … [Read more...] about Mobile and Slow-Moving Operation at Work Zones for Aging Transportation Infrastructure Maintenance
Influence Range and Traffic Risk Analysis of Moving Work Zones on Urban Roads
There is a body of literature on the influence range and traffic risk of fixed work zones. However, relatively few studies have examined the effect of ubiquitous moving operating vehicles, such as … [Read more...] about Influence Range and Traffic Risk Analysis of Moving Work Zones on Urban Roads
Identification and Characterization of Mobile Work Zones Using Floating Car Data
This paper describes a methodology for the identifying active mobile roadworks zones based on detecting the forward forming shockwave associated with the congestion front with the use of vehicle probe … [Read more...] about Identification and Characterization of Mobile Work Zones Using Floating Car Data
