concluded from his analysis that the price
of transit services did not have much effect on choice. This
could be due to limited mobility options and income constraints
among some segments of the population, as they
found that the paratransit service was an important mode
for many people, especially non-drivers. Not surprisingly
traditional bus services were found to be unattractive to
most people, especially those with walking difficulties.
Buses that are accessible to disabled people did not have
a large effect in increasing the desirability of the mode.
Stern found that taxis are not highly regarded and speculates
that this may be due to taxi drivers being unhelpful
to older and disabled customers. These results are certainly
informative about the importance of providing door-todoor
dial-a-ride services, however, the differences between
a rural area and an urban area such as London make generalization
difficult.
