Congestion Management
    • Congestion Management main image

Every county in California is required to develop a Congestion Management Program (CMP) that looks at the links between land use, transportation and air quality. In its role as Riverside County’s Congestion Management Agency, RCTC prepares and periodically updates the county’s CMP to meet federal Congestion Management System guidelines as well as state CMP legislation. The Southern California Association of Governments (SCAG) is required under federal planning regulations to determine that CMPs within its region are consistent with the Regional Transportation Plan. RCTC’s current CMP was adopted in December 2011.

In Riverside County, the Enhanced Traffic Monitoring System within the CMP consists of the installation of traffic counters at call box and Caltrans traffic monitoring sites. This enables RCTC to have immediate access to traffic count data to effectively monitor the highway system for deficiencies. The count information can also be used for project evaluations and planning activities.

RCTC does not require Traffic Impact Assessments for development proposals. However, local agencies are required to maintain minimum level of service (LOS) thresholds included in their respective general plans. Therefore, Traffic Impact Assessments on developments are required by the local agencies. Local agencies whose development impacts cause the LOS on a non-exempt segment to fall to “F” must prepare deficiency plans. These plans outline specific mitigation measures and a schedule for mitigating the deficiency.
