June Webinar by Camila Balbontin

06 / 06 / 2018

BRT+ Centre of Excellence invites to its monthly webinar series to share timely public transit research and encourage ongoing collaboration. Our Webinar of June is:

“Do preferences for BRT and LRT change as a voter, citizen, tax payer, or self-interested resident?” 

Presented by Camila Balbontin, Postgraduate Research Fellow at the Institute of Transport and Logistics Studies (ITLS)on June 20th, 9:00 Australian Eastern Daylight Time (June 19th, 19:00 Chile). There will be sent all the information needed to connect to the platform.

To join the webinar you can register here.

For future webinars, you can register here to be noticed. Soon, at this post, you will find the Video and Slides from this webinar, and here from previous meetings.



Interest in modal preferences remains a topic of high interest as governments make infrastructure decisions that often favour one mode over the other. An informative input into the infrastructure selection process should be the preferences of residents, since they can guide buy in to support political and bureaucratic choice making. Cost-benefit analysis (CBA) uses the self-interest preferences of individuals as the relevant interpretation of ‘individual preferences count’, which in aggregate represent the benefit to society of candidate investments. However, the CBA benefit calculations can be rather restrictive with other preference metrics often being identified and used in various ways to inform the debate on infrastructure support. In this paper we assess how the preferences for bus rapid transit (BRT) and light rail transit (LRT) change with different roles the residents may play: a citizen or altruistic resident, a self-interested resident, a tax-payer, and as a voter. We use data collected in five countries to investigate preference differences and also to establish whether there is replicability of the findings across geographical jurisdictions. The findings suggest that there are, in general, noticeable differences in preference revelation across the metrics; however there are also both similarities and differences in the role of specific attribute drivers (as represented by willingness to pay, and magnitude of support for a specific mode) within and between preference metrics across countries.

Camila Balbontin is a Postgraduate Research Fellow at the Institute of Transport and Logistics Studies (ITLS). In February 2018, she completed her PhD under the supervision of Professor David Hensher where she focused on integrating decision heuristics and behavioural refinements into travel choice models. She was awarded the ITLS prize for Research Excellence in Transport or Logistics 2017. Camila also holds a bachelor degree in the field of Civil Engineering with a diploma in Industrial Engineering and in Transportation and Logistics from Pontificia Universidad Católica de Chile. She did her MSc degree at the same university under the supervision of Professor Juan de Dios Ortúzar. Her MSc thesis estimated the valuation of households and neighbourhood attributes in the centre of Santiago.

As a Postgraduate Research Fellow, her main focus is choice modelling and travel behaviour. She is currently working on projects related to the BRT Centre of Excellence, business location decisions, hybrid modelling, value uplift, among others.
