摘要: The subjects of this comparative case study are Orenco Station, a transit-oriented development (TOD) in the Portland region, and Station Park, a transit-adjacent development (TAD) in Salt Lake City region. The peak parking demand at Orenco Station is less than one half the Institute of Transportation Engineers (ITE) suburban parking supply guideline. Also, vehicle trip generation rates are about half what is suggested in the ITE guidelines. Vehicle trip generation rates at Station Park show a smaller reduction but still substantial due to the mixed-use nature of Station Park. Parking generation rates are also lower than the ITE guidelines. In terms of metrics often associated with transportation performance, the large-scale TOD dramatically outperforms the large-scale TAD. The adjacent rail station appears to have little effect on the performance of the TAD, but a substantial effect on the performance of the TOD.
