What is "PATH2Go"?


"PATH2Go" integrates a suite of web-based and mobile-phone-based applications to provide travelers with real-time, multimodal transit information. The web-based trip planner allows you to plan and compare trips using any combination of driving and/or transit. You can compare trips using different modes of travel based on travel time, cost, or even the carbon footprint. Once you have planned a trip, you can then send that trip to your mobile phone application, which will provide you with real-time updates on bus or train arrival times.Your mobile phone will even give you an alert when approaching your stop!


The project is actually a research field test that is being conducted by California PATH (Partners for Advanced Transit and Highways) at U.C. Berkeley in partnership with Caltrans, the Research and Innovative Technology Administration (RITA), of the U.S. Department of Transportation), the Metropolitan Transportation Commission (MTC), Santa Clara Valley Transportation Authority (VTA), San Mateo County Transit District (SamTrans) and private partners including NAVTEQ, ParkingCarma, and SpeedInfo. Networked Traveler was funded as part of the U.S. Department of Transportation's IntelliDrive program, and is being conducted from August to November, 2010.


The PATH2Go mobile application was designed to provide both transit and park-and-ride information and alerts. It should not be used while you are driving. "Geofencing" has been incorporated to prevent PATH2Go application to be used when used in a car. When such circumstance is detected, a warning "Application Disabled while Driving" together with a graphical sign (triangle and exclamation point icon) will be displayed.
