LunchUP: Tierra Bills, "Investigating Transportation Equity Using Activity-Based Travel Demand Models"

Activity-based travel demand models can be useful tools for understanding the individual level equity impacts of regional transportation plans, because of their ability to generate transportation measures at disaggregate (individual and household) levels. There are numerous population and environmental (transportation and land-use) factors that together shape the transportation equity outcomes for individuals. In a real world setting, for example, one’s income level, age, gender, ethnicity, residential location, work location, and access to various travel modes all play key roles in determining how one is affected by the transportation system. In such a complex system where numerous population, land-use, and transportation factors are at play, the influence of these on distributional outcomes can seem impossible to disentangle. In this presentation, I will discuss the usefulness of analyzing transportation equity outcomes using a set of distributional comparisons across different scenarios. This demonstration uses the 2000 Bay Area Travel Survey and (activity-based) destination choice model. The findings show that activity based models in conjunction with distributional comparisons are capable of revealing the population and environmental factors that result in clear “winners and losers” due to transportation changes. 

These sessions are a response to requests from faculty and students to learn more about what’s going on in the field in an informal environment. We hope this can inspire emergent thoughts and connections that will inform our scholarship.

Lunch is included, please bring a drink.
