Target Completion Date: February 28, 2019 Safety, Operations, and Traffic Engineering
The Hampton Roads Bridge-Tunnel (HRBT) is a source of significant recurring and nonrecurring congestion. Iincidents cause disruptions to the traffic flow, further exacerbating the conditions at the already congested corridor. In particular, over-height (OH) trucks cause frequent stoppage of the traffic since the tunnel clearance in the older westbound (WB) direction is lower than the newer eastbound tube, 13’6” compared to 14’6” in the eastbound direction. In order to turnaround an OH truck at the tunnel islands, traffic in both directions is interrupted or stopped. To address the OH violations, the Virginia Department of Transportation (VDOT) is in the process of installing an additional OH detection sensor and new alert signs upstream of the WB inspection station. This installation is expected to be completed by November 30, 2017. This proposed research will result in a final report documenting important characteristics of the violators and the impacts of the new OH vehicle detection system to be installed at the HRBT.
