Portland-Milwaukie Light Rail Project - FEIS - Volume 1 - TriMet

5.2.1.4 Transit Network’s Ability to Accommodate Future Growth in Travel Demand
Light rail can carry approximately five times as many riders per two-car train than a standard 40-
foot bus. At 2030 service levels, light rail will operate at 7.5-minute headways during the peak
period in the peak direction and at 15-minute headways during the off-peak period. This
frequency can be expanded to serve more riders as demand warrants. The light rail line can carry
approximately 2,000 riders per hour in each direction, and future expansion of the light rail line
has capacity to serve 5,000 riders per hour in each direction.
5.2.1.5 Minimize Traffic Congestion and Traffic Infiltration Through Neighborhoods
Table 5.2-7 shows that light rail project would reduce PM peak vehicle demand at key points in
the corridor. The largest reductions (about 2.5 percent) would be on SE McLoughlin Boulevard
and adjacent parallel streets south of SE Powell Boulevard with the LPA to Park Avenue. The
MOS to Lake Road also provides a reduction, while the LPA Phasing Option less reduction.

As shown in Table 5.2-8, the LPA to Park Avenue and the MOS to Lake Road will reduce VMT,
VHT, and VHD compared to the No-Build Alternative.
