... 14 TDFM Updates The performance metrics identified in the preceding chapter will provide useful metrics that can help practitioners examine whether travel demand in the jurisdiction has been altered by NMO adoption. This chapter will provide direction to transportation agencies on how to implement TDFM updates for the selected components.

In an effort to identify the potential impact of NMOs on HH trip rate, the authors present a simulated scenario using 2011 Atlanta household survey data (Household Travel Survey, 2011)
