Valuing urban attributes for a bus corridor in a residential choice experiment context

  1. 1. The valuation of urban attributes in a bus corridor by stated preferences experiments Isidora Navarro, Patricia Galilea y Ricardo Hurtubia 1/29/2016
  2. 2. Introduction Context Motivation Hypothesis and Objectives
  3. 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.
  4. 4. 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.
  5. 5. Methodology Stated preference experiment Identification and selection of attributes Design of the experiment
  6. 6. 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
  7. 7. Identification and selection of attributes The urban attributes that were selected at first were: Green areas Sidewalk Bike lane Bus corridor
  8. 8. Identification and selection of attributes After a pilot survey, we kept three attributes: Green areas Sidewalk Bike lane Bus corridor
  9. 9. 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?
  10. 10. Pilot Survey Vitacura Pajaritos
  11. 11. Pilot survey: Vitacura
  12. 12. Pilot survey: Pajaritos
  13. 13. 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.
