Why does the Institute of Traffic Engineers (ITE) recommend using a value of 9.6 trips per day for single-family residential properties?

The ITE "Trip Generation" report provides guidelines for traffic engineers and planners to understand how proposed land uses might add traffic to a local street system. The report presents results of surveys taken at existing land developments, and categorizes the results by type, time of day, how it compares to the size of the use. Single-family residential developments are among the most surveyed category of uses in the entire volume. Over 400 studies have been conducted at neighborhoods around the country.

On average, 1 new housing unit will generate about 9 to 10 one-way vehicle trips each weekday. Some houses have less, other have more; but for a larger neighborhood with a range of family sizes, income levels, number of licensed drivers and registered cars, the average is a good indicator of overall trip intensity. What does 10 one-way vehicle trips look like? For an average family, it could include some combination of the following:

  • Leaving and returning from work (2 one-way trips)
  • Taking a child to school in the morning and returning to pick them up in the afternoon (4 one-way trips)
  • Driving age children going to and from a friend's house (2 one-way trips)
  • Trip to and from shopping (2 one-way trips)
  • Trip to and from family member's sporting event (2 one-way trips)
  • Local deliveries and service providers (U.S. Mail, FedEx, Trash/Recycle pick-up)
  • Trip to and from the doctor/pharmacy (2 one-way trips)
  • Trip to and from a restaurant of any type (2 one-way trips)
  • Trip to and from the recreation center or exercise facility (2 one-way trips)
