IntroductionContext
Motivation
Hypothesis and Objectives
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.
Hypothesis and Objectives
The hypothesis of this work is that a methodology can beperformed to valuate urban attributes and transport attributes.
The aim is to identify and valuate attributes that improve theenvironment of neighbourhoods , in order to incorporate theminto the cost-benefit analysis of future transport projects in Chile.
MethodologyStated preference experiment
Identification and selection of attributes
Design of the experiment
Stated preference experiment
Respondents faced a residential location experiment
They had to choose between two images that represent theirneighborhood. We sampled four different neighborhoods ofSantiago, Chile: Vitacura, Santa Rosa, Gran Avenida and Pajaritos
Identification and selection of attributes
The urban attributes that were selected at first were:
Green areas
Sidewalk
Bike lane
Bus corridor
Identification and selection of attributes
After a pilot survey, we kept three attributes:
Green areas
Sidewalk
Bike lane
Bus corridor
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?
Pilot SurveyVitacura
Pajaritos
Pilot survey: Vitacura
Pilot survey: Pajaritos
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.
