![]() ![]() Re-evaluating the transit modeling framework offered the opportunity to develop a new system with these properties in mind. The previous framework did not include some of these model properties, making them vulnerable to FTA scrutiny. Consequently, FTA has released recommended model properties and other findings to the modeling community in the hopes that future modeling systems will avoid these practices (or continuing them in some cases). In fact, they may render the model results inexplicable. Modeling insights gained from FTA indicate that many ideas initially considered good practice in fact have many bad or undesirable properties during forecasting. Second, the Federal Transit Administration's (FTA's) oversight of forecasts related to the New Starts program over the past five years have provided a number of adjustments to transit model "state of the practice" concepts. ![]() So different, in fact, that maintaining the existing framework in its entirety was not a viable option. Voyager's transit module, Public Transport (PT), is quite different from Tranplan in its format and operation. First, the Florida Model Task Force voted to migrate to the FSUTMS-Voyager platform in 2004. The previous transit modeling framework needed a re-evaluation for two reasons. ![]()
