Travel Behavior/Trip Chaining
Our focus is on "retail" activities because they directly or indirectly account for a large majority of all personal travel. By retail, we mean shopping for goods and services, eating out, and engaging in recreation, social and cultural activities outside the home. These nonwork activities generated almost three out of five person trips in 1995 (Table 5).

Nonwork trips are often chained with work trips and with other nonwork trips to maximize travel efficiency. The data in Table 6 show the importance of trip chains for the Work to Home and Home to Home tours, and the differences between genders. These data suggest that if TOD is to accomplish mode shifting, activities to be located in a TOD should be identified by pinpointing the specific purposes and locations of stops in these tours. Other tours of interest are, of course, the Work to Work and the Home to Work tours.
