Southern Traffic Service Sole Source

This contract is a sole‑source award to Southern Traffic Services for continuous, statewide traffic‑monitoring and data‑management services for the South Carolina Department of Transportation. The agency required an immediate, uninterrupted solution after a competitive solicitation was suspended and a protest was pending. The vendor will operate and maintain continuous count stations (CCS) and weigh‑in‑motion (WIM) systems, provide near‑real‑time traffic data, manage enterprise ITS assets, support emergency‑response interfaces, and deliver portable traffic‑data operations, all while ensuring compliance with federal Title 23 reporting requirements. • Provides full‑service traffic data collection, validation, processing, and reporting for the entire state. • Maintains existing SCDOT traffic‑monitoring hardware/software platforms without service interruption. • Justified as sole‑source because only STS possesses the proprietary integration and historical data needed for immediate compliance.
