The proportion of heavy vehicles is very high on Chinese highways. Slowly moving heavy vehicles cause additional delay in a work zone especially when there is only one open lane in the work zone. In … [Read more...] about Influence of Heavy Vehicles on Traffic Flow in Freeway Work Zones
Study on Improving the Worker Safety at Roadway Worksites in Japan
Work-related accidents at construction sites in Japan resulted in 1,001 fatalities and 44,886 injuries in 1996, but by 2005 these had fallen to 487 fatalities and 27,193 injuries. Among accidents at … [Read more...] about Study on Improving the Worker Safety at Roadway Worksites in Japan
Approximated Headway Distributions of Free-Flowing Traffic on Ohio Freeways for Work Zone Traffic Simulations
Headway or interarrival time (IAT) data of successive vehicles in free-flowing traffic ahead of work zones at six different Ohio freeways (two with two lanes in one direction, three with three lanes, … [Read more...] about Approximated Headway Distributions of Free-Flowing Traffic on Ohio Freeways for Work Zone Traffic Simulations
Evaluation of Work Zone Design Strategies: Quantifying the Impact of Driver Behavior on Traffic Flow and Safety
This paper presents an algorithm that considers the influence of driver behavior on traffic flow and safety when drivers encounter and respond to changing roadway conditions found in work zones. The … [Read more...] about Evaluation of Work Zone Design Strategies: Quantifying the Impact of Driver Behavior on Traffic Flow and Safety
Pavement Resurfacing Intervals in Work Zone Optimization
Lane closures for highway resurfacing involve some intricate tradeoffs between the maintenance cost to highway agencies and the costs of delays and disruptions to motorists. Careful optimization of … [Read more...] about Pavement Resurfacing Intervals in Work Zone Optimization
