County, and the Blumenberg and Haas (2001) study of Fresno County<br />

provide good examples of transportation questions that could serve as a<br />

starting point for designing future surveys of welfare recipients. 1<br />

Another possibility for collaboration with social services agencies would<br />

be to add transportation information to their administrative databases.<br />

One advantage of administrative program data is that such data allow<br />

researchers to link information on residential location and workplace<br />

location. Adding information about such items as monetary costs, mode<br />

choice, travel time, and transportation assistance would expand research<br />

options even further.<br />

Another way to extend current research would be to bring greater<br />

emphasis on low-income populations to transportation planning data<br />

collection efforts. MTC and individual transit agencies within the Bay<br />

Area periodically conduct ridership surveys. Efforts could be made to<br />

oversample low-income and nonwhite populations to ensure that sample<br />

sizes are large enough to do statistically valid analyses on specific<br />

subgroups (for example, low-income Hispanic married households with<br />

children). In addition, ridership surveys could ask respondents to rank<br />

their concerns regarding transit service, including monetary costs.<br />

Adding affordability questions to the ridership surveys could help<br />

identify those groups for whom the cost of transit is problematic, <strong>by</strong><br />

looking at differences with respect to demographic characteristics,<br />

transfer behavior, transit providers and routes. 2<br />

Another avenue for possible extensions to ongoing research is to add<br />

more information on monetary costs to national transportation surveys.<br />

The National Household Travel Survey, the Census long form, the<br />

American Community Survey, and the American Housing Survey all<br />

contain helpful data on transportation but do not address monetary<br />

2 In the future, the TransLink® card will become a useful mechanism for collecting<br />

data and will be able to link information on travel behavior to information about the cost<br />

of the trip. However, as the TransLink® system is currently set up, its relevance for<br />

analyzing the low-income population is somewhat limited because it does not link the<br />

travel information to any passenger characteristics (such as income level). One could<br />

instead do analyses at the neighborhood level—however, it will not be possible to identify<br />

where bus trips originate or end unless GPS is installed on the buses.<br />
