Abstract
The impact of Bay Area Rapid Transit (BART) proximity on morning and afternoon peak-hour vehicle trips generated by Transit-Oriented Apartments (TOAs) was observed. BART is one of the busiest rail transit system in the U.S. located in the. It connects San Francisco and the Peninsula region to the East Bay of the San Francisco Bay Area. Ten TOAs, both in the East Bay and Peninsula region, were selected near ten BART stations. The morning and afternoon peak-hour volumes were observed from 6:00 a.m. to 9:30 a.m. and 4:00 p.m. to 7:30 p.m., and then compared with the peak-hour trips estimated by the Trip Generation Manual (8th Edition) published by the Institute of Transportation Engineers (ITE). The analysis and comparison of observed trip generation data with ITE estimates suggests that fewer peak-hour vehicle trips were generated both in the morning and afternoon, however the impact varied from site to site. Most TOAs showed a reduction in the morning and afternoon peak-hour volumes. In the morning, about 19% fewer vehicle trips were produced; whereas in the afternoon, about 50% fewer vehicle trips were produced. It is hypothesized that this reduction in peak-hour trips can be attributed, in part, to the TOA’s proximity to BART.
