Sound Transit rider origin-destination survey and analysis services

Sound Transit is seeking a consultant to conduct an origin-destination survey of riders and analyze travel patterns across its transit network. - Buyer: Sound Transit, part of the Central Puget Sound Regional Transit Authority; no sub-agency or office is specified. - Procurement: Survey planning, design, fieldwork, data processing, analysis, dashboard development, and reporting to support evaluation of the Lynnwood Link and Federal Way Link Extensions, ridership modeling, and equity analysis. - Coverage: Sound Transit Link, ST Express, and Sounder services, plus selected routes operated by King County Metro, Pierce Transit, and Community Transit that serve the extension corridors. - Sampling and fieldwork: Develop a statistically valid sample for route-level ST Express and station-level rail results. Cost assumptions use a target sample of 10% of average weekday ridership and at least a 40% response rate; the final approach will be developed with Sound Transit. Work includes onboard and offboard counts, trained field staff, supervision, and quality assurance. - Accessibility and languages: Prepare questionnaires in up to six languages—Spanish, Chinese (Simplified and Traditional), Vietnamese, Tagalog, Korean, and Russian—and include protocols for deafblind passengers. - Deliverables: Cleaned and weighted data, a data dictionary, analysis documentation, a draft report, an interactive dashboard for trip, fare, and demographic information, and a final electronic report. - Optional work: If authorized, supplementary data collection may use location-based data services or other methods when onboard collection is constrained. - Business participation: No DBE participation goal is set; small-business participation is encouraged. The procurement may receive Federal Transit Administration financial assistance. - Named vendors: RSG and ETC are identified in the materials as having conducted a prior Sound Transit survey; neither is specified as the vendor for this procurement. No OEMs or vendors are named for the requested new work.
