Feature request: equity evaluation using census data

Overlay data source like U.S. Census American Community Survey to get demographic distributions by geographic region. Draw demographic characteristics for travelers as part of trip generation based on a given traveler's location. This could be used to show how travel time varies by income (or race) in a given street configuration. So, you could see whether a given modification made for a more (or less) equal distribution of travel times across demographic factors.

Side note: demographic data could also be paired with other data sources like PSRC's Household Travel Survey Data (Seattle-area only and not generalizable to other cities) to inform mode choice. Not sure if something like this is already incorporated into the mode choice model.
