Using new big data sources to inform travel demand models

Description: In recent years, various new big data sources are getting popular for mobility research. Despite its potential advantages such as being less expensive and large in sample size, people are still doubting if such data can really complement or replace traditional travel survey data because the information of these data is usually limited. For example, activity purpose of the trips is typically missing, and personal attributes are also unavailable mainly due to privacy reasons. In this project, I will try to answer the following research questions by conducting several case studies: For travel demand modelling, can we completely replace traditional travel survey data with the new big data? What changes should be made to the existing travel demand models if they are fed the new big data? Can these new big data bring new insights on human mobility behaviour that has never been revealed in survey data?
