T-MAP: Trail Monitoring and Assessment Platform

The core of the T-MAP platform is a suite of general analytical models that can be used independently for a specific purpose, or in concert, depending on a community’s needs and goals.
There are three core models:

  • A GIS-based method for measuring trail system connectivity
  • A trail-use demand factoring and forecasting model
  • A set of impact assessment tools that translate
    trail use into dollars related to health and transportation impacts.

The platform includes a set of data collection instruments that will set a next-generation standard for active transportation research. To develop T-MAP,
RTC will collect data on trail use and trail users in 12 urban areas throughout the U.S.
