An Alternative Design for Traffic Intersections With Work Zones by Using Pre-signals
The lane closures caused by the work zone at the approaches create a negative impact on the operational effectiveness of the signalized intersections. This paper presents an innovative design for … [Read more...] about An Alternative Design for Traffic Intersections With Work Zones by Using Pre-signals
Safety Impacts of Signalized Lane Merge Control at Highway Work Zones
Lane closures due to highway work zones present many challenges to the goal of ensuring smooth traffic operations and a safe environment for both drivers and workers. Late merge behavior at a work … [Read more...] about Safety Impacts of Signalized Lane Merge Control at Highway Work Zones
Safe Way to Go
As a critical part of highway construction and maintenance activities, flagging operations could benefit from the use of automated flagger-assistance devices (AFADs) to improve the safety of flagging … [Read more...] about Safe Way to Go
Field Evaluation of Pilot Vehicles and Portable Traffic Control Signals With and Without a Flagger
The national Manual on Uniform Traffic Control Devices (MUTCD) does not prohibit the use of a pilot vehicle in conjunction with portable traffic control signals (PTCSs), but it does require that a … [Read more...] about Field Evaluation of Pilot Vehicles and Portable Traffic Control Signals With and Without a Flagger
Portable Traffic Signals in Conjunction with Pilot Car Operations at Two-Lane, Two-Way Rural Highway Work Zones
A portable traffic signal (PTS) system is designed to move traffic through two-way rural highway work zones with one lane open to traffic. The primary objective of this study was to evaluate the use … [Read more...] about Portable Traffic Signals in Conjunction with Pilot Car Operations at Two-Lane, Two-Way Rural Highway Work Zones
