Pioneer ICM site in Seattle – SoDo Corridor Vinh Q. Dang, WSDOT
Why our site needs ICM • Geometric constraints / opportunitiesCompact corridor - alternate routes and modes are within 1 mile widthInterchanges are adequately spaced
Why our site needs ICM • Operational challengesFlat peaks – Unstable flow on I-5Sharp peaks – Unused capacity on arterialsMajor blocking incident affects the adjacent networks
Why our site needs ICM • Multiple jurisdiction operating individual networks within the corridorState – FreewaysCity of Seattle – ArterialsTransit agencies – Bus, Train
Balance load Share and disseminate real time information pertaining to corridor Promote and accommodate cross network modal & route shift Manage capacity-demand relationship within corridor in real time Cross jurisdiction control – provision to assume control during off hours. How ICM will help our Site
Who are our ICM Stakeholders • Washington State DOT • Washington State Patrol • City of Seattle • King County Metro Transit and Road Services • Sound Transit • Puget Sound Regional of Councils (MPO) • FHWA • FTA
How our Site defined Roles and achieved Buy-in among ICM Stakeholders • Lead agency – facilitator among partners. • Agency maintain primary control of its network & assets • Agency retain it’s ownership and operation responsibility • Operational agreement to jointly operate specific ITS devices identified as critical for the corridor. • “Buy-in” takes time and effort. Working together to develop corridor goals, needs and to answer “what is in it for us”.
How our ICMS will facilitate ICM • Serves as Central Information Repository (CIR) for all networks in the corridor • Processes and disseminate corridor specific ATIS • Presents a comprehensive (transportation) system status to support / assist congestion management decision.
Lessons Learned – Operational • Route shifting is always sensitive. • Need to make and prove that the alternate route is capable.
Lessons Learned – Operational • Route shifting is always sensitive. • Need to make sure and prove that the alternate routes or modes are ready and capable.
Lessons Learned – Technical • Developing ConOps is an iterative processBiggest huddle - from agencies wish list to corridor’s need • Constraints during the system requirements development might result in revision to ConOps. • ICD for legacy system • Some in-house application developed by the agency is on a fast (deployment) track - minimal / no documentation!
Lessons Learned – Institutional • Jointly operate ITS device or share control of devices(who, what, when protocol) • Partnership, partnership, and partnershipParticipation in the regional traffic operation committee foster partnershipDiscuss ICM strategies together during “happy hours” also foster partnership
