Energy-efficient Mobility Systems


SmartBay project implements a typical working day mobility scenario within the nine counties of San Francisco Bay Area.

As of 2015, the total population of the area is 7.5M people, with an estimated 3.4M commuters, out of which 350K are using public transport as their only commute mode. The road network used in the scenario consists of a total of 96000 links, with a mix of freeways, state routes, all major arterial and countryside roads. The network was extended with all major public transit lines available through General Transit Feed Specification (GTFS) provided by the respective agencies. The major rapid rail carrier is a Bay Area Rapid Transit system that serves 400K daily trips over 4 inter-connected lines.

SmartBay scenarios use the anonymized cell phone data logs to adjust the mobility demand models. The cell phone data are stored and processed internally at secure servers managed by AT&T Research.
