The NHTS Add-on Program

States and MPOs have the unique opportunity to purchase samples of the household travel survey when it is conducted, approximately every five to seven years. These additional samples, along with random national samples collected in the add-on area, are compiled into a cleaned geocoded database ready for application to local planning and forecasting. Trips of ALL lengths, for ALL purposes, and for ALL modes are collected.
