Treating Potential “Back-of-Queue” Safety Hazards Training Module
The purpose of this document is to highlight strategies that can help reduce the work zone congestion that increases back-of-queue crash risk. Studies have shown that rear-end crashes in the advance … [Read more...] about Treating Potential “Back-of-Queue” Safety Hazards Training Module
Exploring Traffic End-of-Queue in a Temporal Spatial Diagram and Applications for Work Zone Safety Analysis
Vehicle queue presence and the location of the end-of-queue as a result of work zones and incidents is important for traffic management and can be acquired from inspecting each vehicle's actual … [Read more...] about Exploring Traffic End-of-Queue in a Temporal Spatial Diagram and Applications for Work Zone Safety Analysis
Work Zones as a Series of Bottlenecks: Developing a Methodology to Estimate Delay and Queue Length
Past studies on queue length and delay estimation have simplified work zones as a single bottleneck. This simplification may produce considerable error in queue length and delay estimations. In fact, … [Read more...] about Work Zones as a Series of Bottlenecks: Developing a Methodology to Estimate Delay and Queue Length
Decision Tree–Based Model for Estimation of Work Zone Capacity
The ability to accurately estimate work zone capacity is imperative, as it is a key input to estimate queue length and traffic delay at work zone. This paper thus aims to develop a decision tree-based … [Read more...] about Decision Tree–Based Model for Estimation of Work Zone Capacity
