How effective will a BRT system going to be in Santiago de Chile? Case studies
Urban transportation in third world countries has always been a political and
economic issue. Not only because of the strong necessity it represents but
because of the tendency of these places to copy first world projects regardless of
the required National capital or the population attitude change that such
For these countries it is important to understand that these solutions are not
always the most adequate; not only because of the investment of capital but
because of the environmental and social impacts have these approaches implies.
Several countries around the world have attempted to solve the transportation
problem, some of them have succeeded and some others have discovered flaws
in their approaches. This research project considers two cities that are
considered successful by using the same system, a Bus Rapid Transit System
(articulated buses). One of them, Curitiba, has been using the solution for more
than twenty years and the other one, Bogota, is almost ten years old. If this is
true, the application of the same system into a similar situation will be just as
effective, in other words, if the traffic situation in Santiago de Chile is just as
inadequate as Curitiba and Bogota where, the solution will be just as good.
The primary objective is to answer the question: what would have happened if
the BRT system was never implemented in these two cities?
The proposed methodology is to compare the congestion levels with and without
the BRT systems, measured as number of private vehicles per capita and
number of buses per capita in both cities.
The WITH situation is determined by demographic data, but the WITHOUT situation
requires development of a regression model to project historic measurements to
the point where the transportation system was implemented in each one of the
Both models were developed with correlation factors higher than 95%, which
means that they represent reality in a very close manner.
Once the data is projected it is possible to compare data tendencies. In this case,
both cities show lower Congestion Levels after the new system started to work.
This means, from the approach of the planner that the proposed system was effective
and its application in the Similar Environment is most adequate.
From the transportation engineering approach, the results are positive and this
marks a step toward a more defined exercise, which is, to gather more
information to be able to develop a more detailed study using both cities
transportation networks and be able to measure additional quantities like travel
times and delays.
