Light Rail Loop
Travel Time
Provides greater speed and reliability over Baseline 2020 transit operations in the corridor. Provides better speed and reliability compared to short express bus. Provides the best speed and reliability of the transit options because LRT is in its own right-of-way.

Improves time to travel on transit between downtown Portland and downtown Vancouver in the evening peak period:

Baseline = 41 min.
Express Bus - Short = 36 min.

Significantly improves time to travel on transit between downtown Portland and downtown Vancouver in the evening peak period:

Baseline = 41 min.
Express Bus - Long = 15 min.

Significantly improves time to travel on transit between downtown Portland and downtown Vancouver in the evening peak period:

Baseline = 41 min.
Light rail loop = 16 min.

Does not maintain transit travel times in the I-5 corridor:

Transit travel times with express bus short will be approximately 9 minutes longer than they are today.

Maintains transit travel times in the I-5 corridor:

Transit travel times with express bus long will be approximately the same as they are today

Maintains transit travel times in the I-5 corridor:

Transit travel times with light rail will be approximately the same as they are today

Least change in transit travel time between Portland and Vancouver High transit travel time savings - is equal to the LRT Loop option. High travel time savings - equal to Express Bus - Long.

Increases transit ridership over baseline. Number of people using transit during the evening peak period:

  • Baseline 2020 = 6500 riders
  • Express Bus - Short = 900

Increases transit ridership over baseline. Number of people using transit during the evening peak period:

  • Baseline 2020 = 6500 riders
  • Express Bus - Long = 10,600

Increases transit ridership over baseline. Number of people using transit during the evening peak period:

  • Baseline 2020 = 6500 riders
  • Light Rail Loop = 12,600

This option, however, has the lowest ridership attraction compared to other transit options:

  • Express Bus - Short = 9000 riders
  • Express Bus - Long = 10,600 riders
  • Light rail loop = 13,000 riders

This option has the second highest ridership attraction compared to other transit options:

  • Express Bus - Short = 9000 riders
  • Express Bus - Long = 10,600 riders
  • Light rail loop = 13,000 riders

This option has the highest ridership attraction compared to other transit options:

  • Express Bus - Short = 9000 riders
  • Express Bus - Long = 10,600 riders
  • Light rail loop = 13,000 riders

Does little to promote transportation choice. For instance,

  • Transit ridership in downtown Vancouver increases by 8% for express bus-short option compared to 40-50% with LRT

Like Express Bus - Short does little to promote transportation choice. For instance,

  • Transit ridership in downtown Vancouver increases by 10% for express bus-long option compared to 40-50% with LRT

Does the most to promote transportation choice. For instance,

  • Transit ridership in downtown Vancouver increases by 40-50% for LRT compared to 8-10% with Express Bus.

Environmental Impacts

Moderate environmental impacts that are difficult to avoid and will need to be mitigated.

Least impacts of construction on the natural environment and land use impact of any transit option.

Moderate environmental impacts that are difficult to avoid and will need to be mitigated. Moderate environmental impacts. Refinement of various alignment options design could reduce or avoid many of these impacts.

Displacements
One displacement directly from express bus due to the fact that it operates on the highway in already established right-of-way. One displacement directly from express bus due to the fact that it operates on the highway in already established right-of-way.

Highest number of displacements of the transit options (79)

The number of displacements may be reduced with alternative routes or alignments of light rail.

The high number of displacements is due to the fact that light rail has its own new right of way.

Cost
  • $14 million ($2001)
  • Least cost of any transit option.
  • Express bus is the least cost transit option due to the fact that it operates on the highway in an already established right-of-way (see 3 vs. 4 Lane).
  • $32 million ($2001)
  • Express bus is a lower cost transit option due to the fact that it operates on the highway in an already established right-of-way (see 3 vs. 4 Lane).
  • $1,222 million ($2001)
  • Highest cost of the transit options.
  • High cost is due to the fact that it operates on its own right-of-way and with a track system.

Other

Compared to light rail transit (LRT), buses have the following advantages:

  • Buses can be flexibly routed to serve different origins and destinations, and to address particular traffic congestion problems
  • Buses can effectively serve outlying population centers such as Battle Ground and Ridgefield
  • Buses can readily be placed on new routes
  • Compared to light rail, express bus serves a more limited transportation market. Express bus, as evaluated, is point-to-point service that serves the commuter market and runs Monday - Friday in the a.m. and p.m. peak periods only.

Compared to express bus, LRT has the following advantages:

  • Does the most to promote transportation choice (transit ridership in downtown Vancouver increases by 40-50% with LRT, compared to 8-10% for express bus options).
  • Serves a range of trip purposes throughout the day, seven days a week.
  • Light rail can provide service to multiple points along the line and be a catalyst for community redevelopment.
  • Reinforces the Vancouver and Portland Central Cities and Regional Centers such as Vancouver Mall and Gateway.
  • Across all measures, I-5 performs better when paired with Light Rail Transit than with Express Bus Transit because Light Rail attracts more riders.
  • Completing the LRT system is consistent with regional and local goals.
  • A low span Columbia River bridge with its occasional bridge lifts would compromise light rail operating reliability.
