Spatial-Temporal Varying Coefficient Model for Lane-Changing Behavior in Work Zone Merging Areas
This study investigates the lane-changing behavior in work zone merging areas during the period from the time of starting a lane-changing maneuver to that of completing the lane-changing maneuver. … [Read more...] about Spatial-Temporal Varying Coefficient Model for Lane-Changing Behavior in Work Zone Merging Areas
Estimation of Road User Costs for Work Zones in Data-Limited or Time-Constrained Environments
This paper considers the problem of estimating road user costs (RUCs), such as travel time and delays, for roadway construction projects under time and data limitations. RUCs measure the mobility … [Read more...] about Estimation of Road User Costs for Work Zones in Data-Limited or Time-Constrained Environments
Integrated Control Method for Freeway Work Zones Under Partially Connected Vehicle Environment
Highway work zones can cause traffic congestion and even traffic accidents. Dynamic lane merging (DM) and variable speed limit (VSL) systems are possible solutions to improve the efficiency of work … [Read more...] about Integrated Control Method for Freeway Work Zones Under Partially Connected Vehicle Environment
Deep Learning Detection of Personal Protective Equipment to Maintain Safety Compliance on Construction Sites
Proper use of personal protective equipment (PPE) is key to minimizing injuries from accidents in construction sites. Past research has attempted at identifying PPE from digital images and videos. … [Read more...] about Deep Learning Detection of Personal Protective Equipment to Maintain Safety Compliance on Construction Sites
