Get high quality on-board survey results and new insights into travel patterns with Foursquare ITP’s Trip Chain Validator. Often, customers responding to an on-board survey will inaccurately report what routes they used for a trip. Foursquare ITP’s tool validates whether travel patterns and routes reported in an on-board survey are indeed feasible on your transit system. For tablet-based on-board surveys, this validation can take place each day to ensure that accurate responses are included in a sample. For surveys already completed, the Trip Chain Validator produces a Validation Report with clear indications of which responses are valid or need further review. Data generated by this tool can also be used to support further planning studies, including assessments of transfer locations and travel and walk times.
