Highway maintenance may cause excessive delay on transportation corridors and networks. Diverting traffic from congested highway work zones and accelerating maintenance progress can mitigate the … [Read more...] about Optimization of Work Zone Schedule Considering Time-Varying Traffic Diversion
Modeling the Location of Crashes Within Work Zones: Methodology and a Case-Study Application
This study modeled the location of crashes within work zones as a function of the lengths of the different work zone segments, traffic volume, weather, and other exogenous factors. A multinomial-logit … [Read more...] about Modeling the Location of Crashes Within Work Zones: Methodology and a Case-Study Application
Expressway Single-Lane Work Zone Capacities with Commercial Vehicle Impacts
Like other government transportation agencies, the Ontario Ministry of Transportation performs regular maintenance and reconstruction of freeways across the province. If lane closures are required for … [Read more...] about Expressway Single-Lane Work Zone Capacities with Commercial Vehicle Impacts
Analysis of Bottleneck Capacity and Traffic Safety in Japanese Expressway Work Zones
This paper explores the characteristics of both bottleneck capacity and traffic safety in work zones of an 150 km two-lane section on the Tomei Expressway in Japan. It is found that vertical sag in a … [Read more...] about Analysis of Bottleneck Capacity and Traffic Safety in Japanese Expressway Work Zones
Traffic Demand Dynamics During Urban Freeway Short-Term Lane Closures
The Texas Transportation Institute (TTI) 2007 mobility report shows traffic congestion is worsening in American cities of all sizes, creating $78 billion annual lost hours and 2.9 billion gallons of … [Read more...] about Traffic Demand Dynamics During Urban Freeway Short-Term Lane Closures
Headway and Safety Analysis of Speed Law Enforcement Techniques in Highway Work Zones
This paper investigated the headway distribution of platooning vehicles, presence of very short headways (<0.7secnond), and frequency of applying of brakes and changing lane in work zones with and … [Read more...] about Headway and Safety Analysis of Speed Law Enforcement Techniques in Highway Work Zones
