"Welfare
Analysis of Informal Transit Services in
Brazil and the Effects of Regulation"
|
My
Tinker foundation grant was used to fund a 5-week trip
to Rio de Janeiro, Brazil, in order to continue field
work for my doctoral dissertation in Urban Planning and
Transportation Engineering. My work involves understanding
how changes in an urban transportation system combined
with the characteristics of its users result in changes
in choices, patterns of travel, and regional economic
welfare.
More
specifically, I am looking at the effects of growing
informality in urban transportation services in developing
countries. Transportation policies addressing informality
will be studied to predict their effects on the populations
dependent on the informal transportation modes. In the
city of Rio de Janeiro, there is such an informal system
connecting the poor northern periphery of the city and
the downtown, via the "Central Station" transportation
terminal. This is the corridor proposed for use in this
study. The system consists of "vanspools" which are best
described as shared taxis or jitneys and operate on fixed
or semi-fixed routes, picking up and dropping off passengers
at any point along the way. The illegal van systems compete
directly with formal bus or rail systems, might serve
areas previously underserved by transit, and/or behave
as feeder services to the formal system. Currently, the
policies proposed by the city to regulate the system
vary between prohibition, recognition and regulation,
and the incorporation of the van services into the formal
transport system.
In
the first part of my field work, completed last year,
I studied the "user-side" of the problem: characteristics
of the users and how they make choices between transportation
modes. I performed interviews with close to 600 different
public transit riders bound for the study area from the
central city. This final trip, funded by the Tinker Foundation
Grant, was dedicated to gathering data on the "supply-side" of
the problem: characteristics of the transportation system
itself. Data gathered included commute times for users
in various areas of the city by rail, bus, and the informal
mode specifically being studied. Other data was collected
to be able to estimate the effects of policies on these
characteristics, such as road capacities, travel speeds,
and the behavior of peak hour versus off-peak traffic.
Finally, interviews were done with several transportation
policy experts at the Federal University of Rio de Janeiro
and several van operators in order to formulate a group
of feasible policy scenarios to be tested in the study.
The
trip was important in helping me complete the last remaining
field work my dissertation needed before its planned
completion during the summer of 2002. I am now putting
together the traveler behavior data with the policy scenarios
to look at their effects on the welfare of populations
in the region.
The
study will lead to an understanding of the consumer-side
benefits of informal transportation operations, which
could be important to help form policies made in the
short term in several Brazilian cities. Understanding
the benefits and costs of informal transport, however,
can have much wider applications. It is rare that a study
focuses solely on the travel behavior of the poor, and
the results might be applicable to other urban areas
within Latin America, and other regions in the world
as well. Urbanization rates are large in developing countries
worldwide, and similar periphery-to-downtown travel patterns
are growing in significance in numerous cities. Furthermore,
there is growing concern for exploding personal vehicle
use in large developing countries like China, India,
and Brazil. Understanding how travelers accept jitney
systems that offer real alternatives to personal vehicles
could be useful in working towards solutions to those
problems. There may even be applications to similar problems
in the developed world where congestion is a growing
problem.
