Congestion Management Process, 2019 Monitoring Report May 2020
The CMP focuses on delivering improved transportation system performance information to decision-makers who must identify the most cost-effective strategies for addressing transportation congestion and improving mobility. This project consists of collecting additional transportation data, analyzing transportation system performance, and annual preparation of a System Performance Report. The performance measures considered for this project include a corridor congestion ratio, speed as percent of speed limit, auto vehicle occupancy, truck percentage, transit seat capacity used, and other transportation measures.
Vancouver Eastside Highway Operations Study
The VEHOPS study was conducted by WSDOT, RTC, and other stakeholders to identify cost-effective projects to improve efficiency and predictability of the I-205 corridor. The study recommends strategies for both southbound and northbound I-205 that will help alleviate bottleneck locations in the AM and PM peak periods. This includes a list of potential viable strategies for further consideration and a list of strategies that were evaluated but are not recommended for further consideration. The VEHOPS study was coordinated with the Urban Freeway Corridor Operations study.
SR-14 Bingen/White Salmon Circulation Study December 2018
SR-14 through Bingen and White Salmon was selected by WSDOT as a corridor that needed to be studied to identify transportation needs.
