An Empirical Assessment on the Effects of Geometry and Non-Geometry Factors in Work-Zone Crashes With Unobserved Heterogeneity

Work zones are uniquely configured and managed by special traffic signs, standard channelizing devices, appropriate barriers, and pavement markings. Unexpected driving conditions through different … [Read more...] about An Empirical Assessment on the Effects of Geometry and Non-Geometry Factors in Work-Zone Crashes With Unobserved Heterogeneity

Work Zone Crash Occurrence Prediction Based on Planning Stage Work Zone Configurations Using an Artificial Neural Network

Work zones are essential to maintain and improve road infrastructure. However, work zones affect traffic safety, and crashes and fatalities associated with work zones in the U.S.A. have increased … [Read more...] about Work Zone Crash Occurrence Prediction Based on Planning Stage Work Zone Configurations Using an Artificial Neural Network

Synthesis Study of Best Practices for Mapping and Coordinating Detours for Maintenance of Traffic (MOT) and Risk Assessment for Duration of Traffic Control Activities

Maintenance of traffic (MOT) during construction periods is critical to the success of project delivery and the overall mission of transportation agencies. MOT plans may include full road closures and … [Read more...] about Synthesis Study of Best Practices for Mapping and Coordinating Detours for Maintenance of Traffic (MOT) and Risk Assessment for Duration of Traffic Control Activities

Impact of Road Environment on Drivers’ Preference to Merging Location Selection in Freeway Work Zone Merging Areas

In view of the compulsory merging behavior and complex driving environment in freeway work zones, the factors influencing drivers’ merging behavior need to be focused on the given road environment. … [Read more...] about Impact of Road Environment on Drivers’ Preference to Merging Location Selection in Freeway Work Zone Merging Areas

Pedestrian Accommodations in Work Zones: Systematic Literature Review and Research Needs

Each year, billions of dollars are spent by public agencies, utilities, and private developers for projects that affect pedestrian safety and mobility during construction. A systematic literature … [Read more...] about Pedestrian Accommodations in Work Zones: Systematic Literature Review and Research Needs

Addressing the Motorcyclist Advisory Council Recommendations: Synthesis on Roadway Geometry, Pavement Design, and Pavement Construction and Maintenance Practices

Roadway geometry, pavement design, and pavement construction and maintenance practices are designed to construct and maintain roadway facilities that provide for motor vehicle travel. Typical … [Read more...] about Addressing the Motorcyclist Advisory Council Recommendations: Synthesis on Roadway Geometry, Pavement Design, and Pavement Construction and Maintenance Practices
