The Balanced Transportation Analyzer, or BTA, is an intricate spreadsheet model that ties together every facet of passenger transport in New York City including transit, auto and taxi. The model makes it possible to measure the effects of changes in auto tolls, transit fares and other variables on traffic levels, travel speeds, time spent traveling, agency revenues, emissions and other "externalities." It contains a number of “pre-packaged” traffic-pricing scenarios which you may, however, modify to test your own what-if scenarios. The BTA thereby offers a transparent and straightforward tool for transport policy-makers and advocates to test the impacts of tolls and other policy traffic pricing proposals. A panel of experts selected by Governor Cuomo recently gave tribute to these aspects of the BTA -- citing its transparency, flexibility, and the solid data that underlies it-- in relying on the tool as the basis for their FixNYC Report.
