One of the most common safety issues at work zones is high speed variation. Nevertheless, few studies have addressed psychological variables to deepen the understanding of drivers’ speed choice in … [Read more...] about Speed Preferences in Work Zones: The Combined Effect of Visible Roadwork Activity, Personality Traits, Attitudes, Risk Perception and Driving Style

Simulator and Field Study of Green Lights on Truck-Mounted Attenuators in Missouri During Mobile Operations
Mobile work zones for various types of moving operations (e.g., striping, pothole patching, sweeping) are an important component in highway maintenance activities which have particular safety issues. … [Read more...] about Simulator and Field Study of Green Lights on Truck-Mounted Attenuators in Missouri During Mobile Operations
Road Sign Vision and Driver Behaviour in Work Zones
The effectiveness of roadwork signs on drivers’ safety is a poorly investigated topic. The present study examined visual fixations of 29 participants to work zone signs, while driving 27 km along … [Read more...] about Road Sign Vision and Driver Behaviour in Work Zones
Optimizing Work-Zone Schedule with Floating Car Data Considering Traffic Diversion and Managed Lanes
Work zones have become the second largest contributor to the nonrecurring delay disruptions of traffic on US highways. The development of a sound model to minimize the total cost (i.e., road user cost … [Read more...] about Optimizing Work-Zone Schedule with Floating Car Data Considering Traffic Diversion and Managed Lanes
Research on the Relationship Between Dynamic Message Sign Control Strategies and Driving Safety in Freeway Work Zones
Several studies have researched the effect of dynamic message signs (DMSs) on the driving safety in work zones. However, only a few studies have examined the design of DMS control strategies in work … [Read more...] about Research on the Relationship Between Dynamic Message Sign Control Strategies and Driving Safety in Freeway Work Zones
Predicting Freeway Work Zone Capacity Distribution Based on Logistic Speed-Density Models
Speed-volume-density relationship and capacity are key elements in modelling traffic operations, designing roadways, and evaluating facility performance. This paper uses a modified five-parameter … [Read more...] about Predicting Freeway Work Zone Capacity Distribution Based on Logistic Speed-Density Models
