The STARs Evaluation Tool: Optimising Network Performance, Road Worker Safety and Road User Safety During Roadworks and Maintenance
The aim of the Scoring Traffic at Roadworks (STARs) project is to optimise network availability, road worker safety and road user safety during roadworks. The objective was to develop a methodology to … [Read more...] about The STARs Evaluation Tool: Optimising Network Performance, Road Worker Safety and Road User Safety During Roadworks and Maintenance
Incorporating Work Zone Configuration Factors into Speed-Flow and Capacity Models
This study aims to develop work zone speed-flow and capacity models, which incorporate work zone configuration factors including the number of work zones, geometrical alignment, work zone speed limit, … [Read more...] about Incorporating Work Zone Configuration Factors into Speed-Flow and Capacity Models
Analysis, Modeling, and Simulation for Traffic Incident Management Applications
Traffic incidents are a major source of congestion in both urban and rural areas. Nationally, roughly 25% of total congestion is due to traffic incidents. Further, traffic incidents create unexpected … [Read more...] about Analysis, Modeling, and Simulation for Traffic Incident Management Applications
Modeling Safety of Highway Work Zones with Random Parameters and Random Effects Models
This paper presents an investigation of traffic safety in highway work zones using detailed data obtained from the results of a survey of project engineers and existing datasets. The observations were … [Read more...] about Modeling Safety of Highway Work Zones with Random Parameters and Random Effects Models
Tree-Based Logistic Regression Approach for Work Zone Casualty Risk Assessment
This study presents a tree-based logistic regression approach to assessing work zone casualty risk, which is defined as the probability of a vehicle occupant being killed or injured in a work zone … [Read more...] about Tree-Based Logistic Regression Approach for Work Zone Casualty Risk Assessment
