ASCE membership is not required, but an ASCE account (free) is required for registration
Our speaker will be Warren E. Hughes, P.E. (Vice President of Transportation Technology and Innovation with ATCS, P.L.C.) and he will deliver his presentation on
Innovative Traffic Management for the I-66 Express Lanes Construction Project
Presentation Topic:
This presentation will describe and discuss innovative Maintenance of Traffic (MOT) concepts, construction mitigation strategies, work zone safety treatments, traffic analyses to support decision making, and temporary traffic control plans that have been implemented on the I-66 Express Lanes construction project. The Public-Private Partnership project entails the construction of two express lanes in each direction over 22 miles of I-66 between I-495, the Capital Beltway, and U.S. Route 29 in Gainesville in Northern Virginia. The project includes the design, modification and reconstruction of a dozen existing interchanges, the design and construction of new interchanges, fly-over ramps, slip ramps, and direct ramp connections for the express lanes, and improvements for arterial crossroads. The project is more than $2B has impacted a major commuter route and important interstate that carried close to 200,000 vehicles per day within a constrained corridor in a populated, well-developed area.
Topics to be presented include the following:
- Innovative use of unmanned aerial vehicles to assess MOT strategies that had been implemented and to investigate and diagnose traffic issues that could be then mitigated.
- Creative traffic analyses to quantify and assess impacts of proposed temporary traffic control plans.
- Measurement and reporting of detailed hourly volumes, travel times and reported crash incidents to monitor traffic conditions in the corridor on a 24/7 basis.
- Use of current, not historical, data on travel conditions to allow extended nighttime lane closures, ramp closures, temporary stoppages, roadway closures and detours.
- Innovative MOT schemes that were successfully implemented during the project, reducing traffic impacts while expediting construction progress.
- Unusual but effective roadway and ramp geometries constructed to allow for the safe and efficient movement of vehicles during periods when original ramps had to be removed.
- Conversion of ramps that were operated as directional ramps on a time-of-day basis to two-way ramps operating on a 24/7 basis.
About the Speaker:
Warren E. Hughes, P.E. (VA), has extensive experience on traffic engineering, highway safety analyses, traffic control plans, maintenance of traffic, and traffic operations analyses on NEPA studies, transportation planning studies, and design projects for highway, interchange, intersection, and transportation improvement projects. Most recently, Hughes served as traffic discipline lead for the VDOT Transform 66 General Engineering Consultant team, which oversaw the design and construction of the I-66 Express Lanes on 23 miles of the I-66 outside the Capital Beltway for VDOT. He is a past president of the Virginia Section of the Institute of Transportation Engineers (VASITE) and was presented their Distinguished Service Award in 2007. He is a past co-chair of TRB’s Safety Data, Analysis, and Evaluation committee, past chair of Methodology on Evaluating Highway Improvements committee, and a past member of TRB’s Operational Effects of Geometrics and User Information Systems committees. He has published numerous articles. He has conducted research for FHWA, the Transportation Research Board, the National Cooperative Highway Research Program, the Institute of Transportation Engineers, among others. He has been a practicing traffic engineer for 40 years in the private sector and is currently a VP of Transportation Technology and Innovation with ATCS, P.L.C., a consulting firm based in Herndon, Virginia, offering full services in transportation engineering, construction managing, engineering and inspection, program management, environmental services, and emergency management services.
