Countywide Travel Demand Model

The Alameda countywide travel demand model is an essential tool for the CMP planning process. The model allows the Alameda CTC to anticipate and forecast the potential impacts of local land development decisions on the major roadways 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 (ABAG) and assumptions of the Metropolitan Transportation Commission’s regional travel demand model. The most recent Alameda countywide travel demand model completed in August 2011 includes land use assumptions updated to ABAG’s Projections 2009 and several revised features.

The CMA released an updated countywide travel demand model in August 2011. The updated model incorporates the Projections 2009 Land Use of Association of Bay Area Governments (ABAG). The Countywide Travel Demand Model is originally expanded from the MTC’s Regional Transportation Model (BAYCAST model) in 2007, and provides more detailed traffic analysis zones, road and transit networks and other details within Alameda County.

Model Vehicle Volumes

Below are the plots of the model volumes for a.m. peak 1-hour, p.m. peak 1-hour, p.m. peak 2-hour, p.m. peak 4-hour and daily for the four Planning Areas of Alameda County. There are separate volume plots for each time period for horizon year for each planning area except for p.m. 2-hour and 4-hour time periods for which the volume plots are combined for all horizon years for each planning area. The volume numbers appear directly on the network roadway links. They are printed quite small, but you can use the Adobe viewer to zoom in on them. The volumes are printed small to show volumes on as many links as possible.
