PÚBLICOS DEL ESTADO Y MUNICIPALES

• Role questions (q_0001): as recommended in the 2009-10 report, we offered “retiree” as an answer option to q_0001, and we excluded respondents who indicated this choice from the analysis.

• In the future, we may refine options given to respondents who were away all week (question q_0012) to distinguish between those permanently/normally away from campus and those temporarily away from campus.

• We eliminated the question about vehicle type (truck, car, etc.), replaced it with a more direct question about fuel type of the vehicle, and also asked respondents to estimate the fuel economy of the gasoline or diesel vehicle they traveled to campus in during the reference week (q_0023 and q_0024). Due to

concerns about the inaccuracy of self-reported fuel economy, we would recommend discontinuing q_0023 and q_0024 for the 2010-11 survey.

• As suggested in the 2009-10 report, we asked bus and train riders to indicate which service(s) they used on each day (q_0026 and q_0028). The responses to these questions proved cumbersome to analyze, so we recommend that these questions are revised or removed for the 2010-11 survey.

• We asked respondents who indicated riding the bus or train whether they drove or got a ride to the transit station (q_0029), and if so, how many miles they live from this transit station (q_0030). This question is part of our ongoing efforts to capture multimodal travel (especially travel that generates VMT and GHG emissions) without making the survey too cumbersome.

• We replaced a vague question about intent to bring bicycles home with a more direct question, "What are your reasons for storing this bike on campus overnight?" (q_0032).

• We changed the answer format of the question about the number of minutes it takes to get to campus to a numerical write-in, rather than a categorical choice. The purpose of this change was twofold: to obtain more precise answers, and to enable comparisons between self-reported time and GIS-estimated time by role and housing location.

• We revised the question about typical circulator mode to instead ask respondents to estimate in percent how much they typically use each mode to get around campus (q_0039).

• We removed the one-time questions about detailed Unitrans use (which lines, type of ticket among grad students).

• Regarding crashes, this year we only asked about bicycle crashes, although we still distinguished between on- and off-campus incidents, asked whether the incident required a hospital visit, and asked if a police report was filed.

• Regarding bike theft, we added several questions about where the bicycle was, what it was locked to, what kind of lock was being used, and the value of the bicycle when it was stolen. We asked the same questions about bicycles stolen off campus (q_0051-65). This sort of detail was meant to be a one-time

section, and we recommend that the bicycle theft section be substantially simplified for next year's survey. • The attitudinal and behavioral questions q_0066, q_0071, q_0073, and q_0074, and q_0076 are unique to

the 2010-11 survey (replacing Q0066 through Q0068 in the 2009-10 survey). Though the results to these questions are not discussed in detail in the report, it is anticipated that the data will be used in future statistical analysis.

• In the results of each campus travel survey, it has become apparent that when freshmen become

sophomores, they tend to bicycle less frequently to campus, opting to take the bus instead. In an attempt to better understand this trend, this year we asked sophomores directly, "Do you bike to class as often now as you did your freshman year?" (q_0068), and if not, "Why do you bike less now? Please indicate

whether each of the following is true or not, and if it is true, please rate how important a reason it is for why you are biking less now." (q_0069). These questions can be excluded from next year's survey. • Given the disproportionate number of staff who live outside of Davis and the substantially higher

tendency of those living outside of Davis to drive alone to campus, this year we asked employees who lived outside of Davis about their reasons for living outside of Davis (q_0077). We also asked all employees about whether they typically run certain types of errands on the way home from campus. We hope to use these results in future analysis to inform the reasons employees are more likely to live outside of Davis or drive to campus.

• We moved several important partitioning questions to earlier in the survey, including questions on gender and housing location (q_0007 and q_0008, respectively).

• We did not ask graduate students question q_0004 about whether they are paid employees of UC Davis for AVR calculation. Next year, we will ask both undergraduate and graduate students whether they are paid employees.

A few ongoing challenges include the following:

• How to reduce the burden on respondents, with particular attention to reducing the perceived time cost and effort required to complete the survey.

• How to measure multimodal travel, without the survey becoming too cumbersome.

• How to measure typical and summer travel, without the survey becoming too cumbersome. • How (and whether) to measure daily transit ridership by agency, without the survey becoming too

cumbersome.

• How to properly define telecommuting, perhaps an increasingly fuzzy concept as more people work anywhere, anytime without thinking of it as replacing a physical trip. Assessing the extent that remote work replaces a physical trip is challenging, as is finding appropriate language for referencing this kind of work.
