The traditional evaluation of transport projects principally considers the benefits
produced by the reduction in journey time of the travellers, but a specific reduction
is not the same for a one-hour trip as for one of 20 minutes, or for a work-related
journey as for a shopping-related journey.
The purpose of this investigation is to
construct a Pattern of Social Behaviour in the use of the city (in space and time),
and specifically the travel time patterns, to use them to prioritise different transport
corridors, in the Metropolitan Area of Barcelona, under a social equity approach, in
The study applies a trip chain analysis (similar to activity-based
models) over the travel survey of the metropolitan area of Barcelona (2001).
results are analysed in a probabilistic dimension of Hagerstrand’s time-geography
The result is a new indicator of access, called functional probability,
which derives from how people move in the city.
This “willingness to spend time
on travel” was used to identify outliers travel time, as a social equity factor, in the
use of the city.
The threshold of 10% of the greater travel time was used to identify
inequitable travel (with different purposes and social class of travellers).
the assignment of these inequity trips shows transport corridors with different
The main conclusion of the research is that taking a social
view of travellers, with regard to their different purposes and social class, in the
form of how they use the city in terms of space and time, is a more realistic
criterion to prioritise different transport corridors, by carrying out the analysis of
who makes use of them, for what reason, and for how long.
