Guide to Alternative Technologies for Preventing and Mitigating Vehicle Intrusions Into Highway Work Zones
Work zone intrusion technologies are designed to warn workers and drivers of potential intrusion, provide a barrier to prevent intrusion, detect and alert drivers and workers during intrusion, and/or … [Read more...] about Guide to Alternative Technologies for Preventing and Mitigating Vehicle Intrusions Into Highway Work Zones
Study of Improved Signal‐Based Merge Strategy in Work Zone Areas Based on Cellular Automata Simulation
Work zones have critical effects on traffic safety and efficiency. Previous researchers have developed lots of merge strategies to regulate drivers’ behaviours, which can be divided into early merge … [Read more...] about Study of Improved Signal‐Based Merge Strategy in Work Zone Areas Based on Cellular Automata Simulation
Toolbox of Low-Cost Work Zone Management Strategies
The Toolbox of Low-Cost Work Zone Management Strategies was developed under the 2016 Federal Highway Administration Work Zone Safety Grant No. 693JJ31750003 awarded to Iowa State … [Read more...] about Toolbox of Low-Cost Work Zone Management Strategies
Modeling Traffic Flow in Work Zone Sections Considering the Effect of Traffic Lights
The relationship between the vehicles’ queuing time and the cycle of traffic lights is studied, and the cycle time of traffic lights is obtained also considering people’s endurance to the red light. … [Read more...] about Modeling Traffic Flow in Work Zone Sections Considering the Effect of Traffic Lights
