| 摘要： | This deliverable provides the results of our analysis of the Neighborhood Travel and Activity Study (NTAS) study, which collected 1-day travel diary surveys for 383 households in surveys in November/December 2012 in areas near two rail transit corridors in Los Angeles, the Red Line (subway) and Gold Line (light rail). We combined these survey results with a supplemental sample of 8,602 households in Los Angeles from the California Household Travel Survey (CHTS), which was conducted during the same time period using a similar survey protocol. The CHTS sample allowed us to increase the sample in the NTAS study area by 313 households and to compare travel patterns for the combined NTAS/CHTS sample in the study area (696 total) with those of CHTS survey households dispersed through the rest of LA County (8,289). First, we provide an overview of the NTAS study design, sample frame, data collection, response rates and sample characteristics. Second, we report results of our factor analysis of NTAS survey results for travel-related socio-psychological factors. Third, we compare daily trip counts by mode and daily household vehicle miles traveled (VMT) for the NTAS and CHTS samples with the 2009 National Household Travel Survey (NHTS) for LA County. Fourth, we conduct a two-stage analysis of demographic, household, and near-residence built environment factors associated with household car ownership and usage. Results suggest differences in walking, transit, and passenger vehicle travel behavior associated with residing in areas with different built environment, land use, and transit access characteristics. |
