Traffic congestion tops the list. According to the survey report, which is available online:
The natural follow-up to that response was to ask respondents if they felt the rail transit system would have an impact on future traffic congestion on the island. This graph displays their responses:
The meaning of "great," “some” and “little” for respondents is of course subjective, but it’s easy to conclude that reducing the number of cars each day from streets and highways by 40,000 vehicles will be a significant factor in reducing congestion.
One of rail’s four major goals is to improve corridor mobility as measured in 2030, the benchmark year. Here’s what the Final Environmental Impact Statement's Section 7.2.1 says about current and future congestion (the FEIS is available online in the project website's Library):
Whether they’ve read the FEIS or just have a gut feeling, the survey suggests most Oahu residents appreciate that Honolulu rail will have a positive effect on traffic congestion. It’s a reasonable conclusion when a completely grade-separated and therefore traffic-free option is available to residents.
Thanks to QMark’s poll, we know that most Oahu residents get it.
