Design and Implementation of a Traveler Information

1 The chief objective of the multi-modal traveler information application, PATH2Go, is to improve 2 the accessibility and quality of real-time traveler information and to make transit a known and vi-3 able choice for travelers. It was developed for a field test on the US-101 corridor, in the San Fran-4 cisco Bay Area, with a primary hypothesis that travelers will benefit from real-time multi-modal 5 traveler information and would therefore be more likely to consider using transit. PATH2Go inte-6 grates a web-based multi-modal trip planning tool that uses real-time information of available tran-7 sit, traffic and parking availability, a web-based search tool that finds real-time transit arrival and 8 schedule information and a mobile application that provides personalized en route transit trip in-9 formation. PATH2Go integrates these major components of traveler information into one platform 10 and therefore makes it easier for travelers to access real-time information. The system architecture 11 of PATH2Go and major design considerations are described in this paper. Enabling technologies 12 including the GPS fusing algorithm and a framework of scenario parsing based on GPS location 13 data are also introduced.
