Based on the Quick Response Urban Travel Estimation Techniques and Transferable Parameters, which land use would have the lowest average vehicle trips per unit?

• A. Fast food restaurant.
• B. High-rise office building.
• C. Assisted Living Facility.
• D. Industrial park.

Answer: (C)

Understanding trip generation by land use shows that residential-type uses with on-site services typically produce fewer vehicle trips per unit than commercial or office uses. An assisted living facility is fundamentally a housing/dr housing-with-services setup, so many residents do not drive and many needs are handled on-site. This reduces external trips per unit, even when staff and visitors contribute some trips. In contrast, a fast food restaurant relies on a steady stream of customers coming and going, a high-rise office building generates numerous commuter trips, and an industrial park involves both employee trips and deliveries. Therefore, the assisted living facility has the lowest average vehicle trips per unit.
