Congestion Management Program

As the congestion management agency for Alameda County, Alameda CTC develops and updates the legislatively required Congestion Management Program, a plan that describes the strategies to assess, monitor and improve the performance of the county’s multimodal transportation system; address congestion and ultimately protect the environment with strategies to help reduce greenhouse gas emissions.

Updated every two years, the Congestion Management Program (CMP) includes five legislatively required elements: Level of Service Standards, Multimodal Performance, Travel Demand Management, Land Use Analysis and Capital Improvements. The CMP ultimately aligns with the long-range Countywide Transportation Plan, the most recent Regional Transportation Plan and Sustainable Communities Strategy (Plan Bay Area 2040) and other related efforts and legislative requirements.

Congestion Management Program Update

The 2019 Congestion Management Program report was approved by the Commission in September 2019.

The June 2020 Amendment to Chapter 6: Land Use Analysis Program.

Prior CMP Updates

The five main elements of the CMP are presented below. Information on SB 743 can be found under the Travel Demand Model tab, including the Alameda CTC VMT Mapping Tool.

Alameda CTC tracks progress toward the adopted Countywide Transportation Plan and Congestion Management Program goals through the Performance Report. This document summarizes how well the transportation system functions in Alameda County. The report is organized by the annual performance of roadways and transit, and the bicycle and pedestrian networks.

The Land Use Analysis Program is one of the legislatively required elements of the Alameda CTC Congestion Management Program. The goals of the Land Use Analysis Program are to:

  • Better integrate local land use and regional transportation investment decisions.
  • Better assess the impacts of development in one community on another community.
  • Promote information sharing between local governments when the decisions made by one jurisdiction will impact another.

Alameda CTC conducts the following activities as part of the Land Use Analysis Program:

Development Project Review

Alameda CTC reviews and comments on Transportation Impact Analyses (TIAs) of large land use development projects to assess impacts of individual development actions on the regional transportation system and to ensure that significant impacts are appropriately mitigated. Alameda CTC integrates its project review with the California Environmental Quality Act project review timeline. Alameda CTC reviews land use projects that will cause a net increase of 100 or more p.m. peak hour trips. Projects can include development projects as well as plans such as specific plans or master plans.

Alameda CTC has established guidelines regarding which land use projects must conduct a CMP analysis as well as types of impacts that should be studied, and acceptable/preferred methodologies. More information is available for project sponsors and local jurisdictions about CMP Land Use Analysis Program Traffic Impact Analysis requirements.

Land Use Forecasts

Alameda CTC works with local jurisdictions to review housing and job projections from the Association of Bay Area Governments (ABAG) and to allocate regional land use forecasts into the Alameda Countywide Travel Demand Model. Alameda CTC works to synthesize ABAG’s regional projections with local knowledge to determine where future development might occur at a detailed local level.

Transportation-Land Use Integration

Alameda CTC oversees and develops a variety of initiatives and planning activities that strengthen connections between transportation and land use:

  • Senate Bill 375 and the Sustainable Communities Strategy
  • Priority Development Area Investment and Growth Strategy
  • Support of infill development
  • Areawide Transportation Impact Mitigation Fees Feasibility Study
  • Community Design and Transportation Program
  • Complete streets policy development and implementation
  • Corridor planning
  • State-level CEQA modernization advocacy
  • Parking standards and policies
  • Regional Transit Expansion Program
  • Sustainable Communities Technical Advisory Program

For more information about these activities, see the Transportation-Land Use Integration web page.

Strategic Monitoring

Alameda CTC monitors trends in performance measures and uses results of this monitoring to inform planning and funding decisions. Monitoring efforts related to transportation-land use coordination include:

Prepared biennially, the CMP requires that level of service (LOS) standards be established and monitored on the CMP-designated roadway system. LOS is a measure of driving conditions and vehicle delay. The objectives of this monitoring effort are to:
  • Determine the average travel speeds and existing LOS.
  • Identify roadway segments in the county that are operating at LOS.
  • Identify long-term trends in traffic congestion on the CMP network.

2018 LOS Monitoring Report

The full 2018 LOS Monitoring Report is available below.

The Alameda Countywide Travel Demand Model is an essential tool for transportation planning in Alameda County. The model allows Alameda CTC and its partner agencies to anticipate and forecast the potential impacts of local land development decisions and changes to infrastructure on travel patterns in the county. The model is periodically updated to be consistent with the most recent land use and socio-economic database of the Association of Bay Area Governments and assumptions of the Metropolitan Transportation Commission’s regional travel demand model.

The most recent Alameda Countywide Travel Demand Model was completed in June 2018 and includes land use and transportation assumptions updated to be consistent with Plan Bay Area 2040. For more information on Plan Bay Area 2040, please go to
