2. Introduction
Context
Motivation
Hypothesis and Objectives

3. Context
At present, the design and cost-benefit analysis of new transport
infrastructure projects in Chile considers attributes mainly
related to transport, but they can give additional benefits, e.g. it
may affect the environment of neighbourhoods
Given this, it is interesting and necessary to characterize people’s
preferences for public spaces and urban amenities.

5. Hypothesis and Objectives
The hypothesis of this work is that a methodology can be
performed to valuate urban attributes and transport attributes.
The aim is to identify and valuate attributes that improve the
environment of neighbourhoods , in order to incorporate them
into the cost-benefit analysis of future transport projects in Chile.

6. Methodology
Stated preference experiment
Identification and selection of attributes
Design of the experiment

7. Stated preference experiment
Respondents faced a residential location experiment
They had to choose between two images that represent their
neighborhood. We sampled four different neighborhoods of
Santiago, Chile: Vitacura, Santa Rosa, Gran Avenida and Pajaritos

8. Identification and selection of attributes
The urban attributes that were selected at first were:
Green areas
Sidewalk
Bike lane
Bus corridor

9. Identification and selection of attributes
After a pilot survey, we kept three attributes:
Green areas
Sidewalk
Bike lane
Bus corridor

10. Design of the experiment
In order to create a realistic survey, the respondents will have to answer
some initial questions:
Where do you live?
How much do you pay in rent per month?

11. Pilot Survey
Vitacura
Pajaritos

12. Pilot survey: Vitacura

13. Pilot survey: Pajaritos

14. We learned that…
It is not convenient to incorporate attributes hard to understand,
like travel time.
It is preferable that images have the same composition.
It is preferable that attributes are not situated in the background.
It is preferable that the respondents can be able to recognize the
neighbourhood.

15. Final Survey
