21 This chapter presents findings on TNC rider characteristics based on the results of recent surveys conducted by the researchers; separate surveys administered by several public transit agencies; and analysis of the TNC trip data described in the previous two sections. Surveys on TNC Awareness and Usage Shared Mobility Survey The first phase of this study, TCRP Research Report 188, included an online survey of more than 4,500 mobility consumers in seven study cities administered in late 2015, with the survey distributed by shared mobility operators and public transit agencies to users of their services.

Findings In addition to the two surveys described above, key rider-related findings from the analysis of the five regions' TNC trip data are also presented to provide additional context.

Transportation Network Company Rider Characteristics 23 The zip codes with the highest levels of TNC activity in the five regions studied tend to share several characteristics. Compared to the cities in which they are located, most of these zip codes have: • Higher household income levels (Seattle is the exception, with only one ZCTA higher than average)

Transportation Network Company Rider Characteristics 25 People who use transit or drive alone do so as part of a routine, while TNCs are used more occasionally. Several points in both the Shared Mobility Survey and the Four Agency Survey suggest that TNCs are being used more as a "gap filling" transportation option and less as a mode for daily commuting or other frequent trips.

26 Broadening Understanding of the Interplay Among Public Transit, Shared Mobility, and Personal Automobiles Travel and wait time were top concerns of those who replaced transit trips with TNC trips. The Four Agency Survey requested details on respondents' most recent TNC trip in the transit agencies' regions and divided these into three classes of trips depending on their orientation to the transit agencies' public transit services (see Table 11)

Transportation Network Company Rider Characteristics 29 Impacts on overall travel behavior vary. In responses to questions on the Four Agency Survey about alternative modes in the absence of or in addition to TNCs, and about TNCs' impact on use of transportation overall, there was little consistency across regions, either in what mode choices were made for different use cases or in how frequently alternatives were used.
