Try this out to guage the difference between survey answers and reality - ask a group of people if any of them take public transit, then ask them to show you their transit passes (daily, monthly, whatever).

Someone in Chicago at least had the foresight to put the rail system in the freeway medians, so commuters stuck in rush-hour traffic can watch the trains at least appear to get to their destination faster than their car is.  So no out-of-sight-out-of-mind problem that transit has most everywhere else.

Peter Foote's responses are excellent.  Although I suspect the smaller
metros have had such an increase in choice riders, because the congestion
and parking cost incentives are not as strong.  

Very good point about the impact of prepaid fare media -- day passes,
monthly passes, etc. -- boosting off-peak ridership.  Prepaid fares help
level the playing field between cars and transit.  Drivers behave as if the
marginal cost of an additonal trip or mile is zero; unlimited-ride passes
induce the same behavior in transit users.

Rail Lines etc


The impact of a new rail line, branch or extension on a system's unlinked
trip count depends upon many factors.

In general terms, the implementation of rail systems should generate new
unlinked trips because they tend by nature to draw new customers, including
suburban men, out of their cars. This is especially true when parking fees
in the CBD are high.  Links can be lost however, when rail route design
allows former bus riders to save one or more transfers previously made on
their commute.

CTA's Orange line (running diagonally across the grid SW from the Chicago's
Loop) which opened 10/31/93, was a bonanza for Pace suburban bus ridership
for routes connecting to CTA at Midway airport. The line exceeded CTA
ridership expectations in part due to high suburban ridership, but also
resulted in some lost linked trips (not individuals) between bus routes -
and of course a substantial shift from bus to rail.

Limited stop express services can add individuals overall but eliminate the
need for some transfers when they cross over route ends.  The X49 for
example, eliminated some transfers (unlinked trips) between routes 49A and
49, however ridership increases and customer satisfaction rose far more than
trips lost.

In Chicago, it is more likely that increases in off-peak discretionary
riding by electronic pass users (30 and 7 day rolling pass markets have
grown substantially since the were re-introduced in the Winter of 1998) are
responsible for a portion of this shift.  New York of course had tremendous
ridership growth when the eliminated the 2nd fare required to move from bus
to rail when their Metro Card was used.  Check with them, but my guess would
be that they have also had big boosts in off-peak riding, etc stimulated by
having pre-paid media available.  DC's Smart Card probably generates many
new rides as well.  Could the impact of just these 3 systems be enough to
cause an increase in trips with no new net gain in riders?  Once you have a
farecard, even a money card rather than a pass, you are much more inclined
to hop on a bus or train to take a trip.  Discounting and the impact of
lowered average fares on ridership through the use of these fare instruments
may also be a factor.

The issue of whether census data questions are complete enough to extract
true mode splits (raised in another thread) is a valid one, especially when
respondents are asked about an entire previous week is a valid one. BUT, I
also think that it is unrealistic to expect more from the Census that can
reasonably be expected.

Reconfiguration of a rail line can cause losses.  When the Dan Ryan/Lake and
Howard/Englewood/Jackson Park were realigned 2/1993 to connect the busy
South and North branches in the Red Line and less busy South and West
branches as the Green Line many transfers which had been recorded as
unlinked trips were eliminated with no real reduction in persons (average
trip lengths expanded).  Reconstruction of a rail line can also cause
losses.  The decision to close the Green line for reconstruction rather than
single track in 1/1994 resulted in bus and offset gains made by the new
Orange Line rail.

The impacts of service changes are often complex.  It likely that changes in
auto ownership and transit riding frequency among fairly frequent customers
over the decade are also an important of the story.  It is also very
difficult to make assessments of persons using a system from unlinked trip
counts.  This is part of why NTD average trip length calculations and
passenger miles estimations are important.
