[CTPP] JTW trend data

We have started looking at several large cities and fast growing cities for which the Profiles have been released. We are seeing slight declines (%) in carpooling, and slight increases in driving alone (%) . Transit shares seem to be about the same. The most important difference from 1990 to 2000 that we have noticed is the large increase in travel time. We are seeing 4 minutes increases in average travel time across the board for both the large cities and the fast growing cities. About ½ minute of this increase may be attributable to the difference in "top coding" travel time, from 99 minutes in 1990 to 200 minutes in 2000. As data for additional States are released, we will compile our results and post to the listserv. We are planning to add Metro Area analysis in addition to examining cities. Elaine Murakami, FHWA
