Sacramento Area Council of Governments (SACOG) is seeking a qualified and forward-thinking vendor to deliver a streamlined and modernized 511 Traveler Information System, delivered exclusively through an interactive voice response (IVR) telephone platform. This new system will replace SACOG’s current multi-channel setup—which includes web, app, and traffic data portal—with a simplified, telephonic-only solution that better aligns with actual usage patterns and regional needs. The primary goal of this Request for Proposal (RFP) is to implement an intuitive, scalable, and fully automated IVR platform that provides reliable, real-time information on roadway conditions, transit, and motorist aid services. SACOG is particularly focused on ensuring that the new system remains reliable and accessible to all users, particularly those without immediate access to a roadside call box or smartphone/internet. By narrowing the delivery method to IVR, SACOG aims to reduce operational complexity while preserving the utility that a 511 system offers. This document outlines the deployment, operation, maintenance, and enhancement of an IVR-based 511 system. The selected vendor will play a critical role in helping SACOG deliver a focused and effective Traveler Information System that maintains regional access to critical Motorist Aid services.
