Project - WASHINGTON: Express Lanes System Concept Study
The Washington State DOT (WSDOT) operates a 225 lane-mile HOV system, as well as two reversible general purpose express lane facilities (one of which will be replaced with light rail). Much of the HOV system has not met adopted speed and reliability standards for several years, impacting transit performance and costs. WSDOT has proposed to convert the HOV and express lane system into a network of tolled express lanes that would continue to serve transit and carpools at no cost, while allowing paying customers to enter the lanes for trips where timely arrival is particularly important. The price would be set dynamically based on traffic conditions in order to maintain high throughput and reliable speeds.
WSDOT believes that an express lane system should be implemented to provide a consistent experience for its users throughout the region. This project will identify and recommend solutions for system-wide policy and design issues to define the express lanes concept for the Puget Sound region, develop specific implementation concepts for I-5, and propose system-level program staging that could be applied to complete the evolution from HOV lanes to tolled express lanes.
Pre-implementation Funds Awarded
December 2009
Anticipated Completion Date
June 2012
October - December 2011 Update
The consultant team has developed draft working papers on user requirements and system design considerations, used by an interagency project coordination group to form initial system design and policy recommendations. Current consultant efforts are focused on identifying potential express toll lane design concepts for Interstate 5 between Tacoma and Everett, WA. This work is close to completion, and work is underway on a final project report. Over winter 2012, WSDOT executives will review design concepts and key policy issues, with particular focus on HOV discounts or exemptions, use of photo tolling, pricing structure and access issues. The final project report is expected by June 2012.
