There is a chart in CIA II that shows that women lag about a 1/2 later than men nationwide
on average. It will be interesting to see what has happened to that distrib since. AEP

Subject: [CTPP] Census JTW
Yes, carpooling went down drastically from 1980-90 and obviously not as dramatic from
1990-2000. We had over 23% JTW trips by carpool in 1980 Nationwide! 1990 it was down to
just over 13% (Nationwide).
I would argue that given the economic condition in 1990 (beaten down) vs. 2000 (just
when the .com bubble was to burst but still upbeat) - losses in carpooling and transit are
not as significant.
Comparing 1995 NPTS and Census 2000 I have the following to offer:
· Trip chaining (the part that goes with JTW) is up during 1990s (NPTS)
· Huge buy-in in favor of 'flex schedules' during 1990s has essentially
marginalized the significance of JTW (there was a drop of more than 5% from 1990 to 1995
in peak hour trip starts in our case)
· Each trip taken by transit would have a front end and a back end trip - (park
& ride or ride & walk) - Census asks for only one mode that covered most of the
distance (is comparable to 1990) thereby undercounting all other trips;
· Vehicle occupancy rate for HBW is a little bit different from what JTW
indicates for the same reason as above - our HBW VOR is less than what census shows
(Tulsa)
Another factor - I have noticed with NPTS is - Women as a percent of peak hour commuting
public is higher than for men (13.6% men vs. 19.7% women in 1995 for Tulsa). It could be
because women tend to keep more regular hours than men. May be 'Rideshare'
programs should focus on Women-only carpools as a potential market share.
Whatever it may be, we might notice with CTPP an increase in share of women in commuting
during peak hours - to somewhat contributing to the erosion in transit patronage, decline
in carpooling and increase in commute times.
