Developing Trip Rates
► Trip rates are developed from Travel Characteristics /
Household Surveys.
► The data for these surveys is obtained through
telephone interviews or mail-back surveys with
members of selected dwelling units.
► Members of the household are asked to keep a trip
diary or log of all trips during a 24-hour period or longer.
► The surveys are continued until sufficient data is
obtained for each cell in the matrix to meet the required
statistical analysis for sampling.

Trip Production Matrix Rates
►Rates are in person trips and are collected by
purpose.
►Transient dwelling units (hotel-motel units) are
assumed to have one auto per occupied room.
►Rates can be calculated by other classifications
such as retired, and working families with children
and without children.
