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 July 2014 includes land use and transportation assumptions updated to Plan Bay Area and several revised features.

Model Vehicle Volumes

(Uploaded 12/29/2014)

Below are the plots of the model volumes for a.m. peak 1-hour, p.m. peak 1-hour, a.m. peak 4-hour, p.m. peak 4-hour and daily for the four Planning Areas of Alameda County. Volume plots for each time period are combined for all horizon years (2010, 2020 and 2040) for each planning area. The volume numbers appear directly on the network roadway links. The volume numbers for each horizon year are indicated by color: 2010 (black), 2020 (green) and 2040 (red). They are printed quite small to show volumes on as many links as possible, but you can use the Adobe viewer to zoom in on them (view at 800 percent recommended).

Performance Measure Maps

(Uploaded 12/29/2014)

In support of Alameda CTC's documentation of the 2013 Model update, the agency has created maps for the three following performance measures: vehicle miles traveled, transit accessibility and miles of congested roads. Maps are available for model study years 2010, 2020 and 2040.  

Vehicle Miles Traveled (VMT)

  VMT  Per Person   VMT Per Employee  
2010 2010
2020 2020
2040 2040

Transit Accessibility

Transit accessibility is based on the number of jobs within a certain number of minutes of travel time by transit.

  Jobs Within 30 Minutes   Jobs Within 60 Minutes   
2010 2010
2020 2020
2040 2040

Miles of Congested Roads 

The color codes indicate network link volume/capacity ratios for the p.m. 4-hour peak period.
