In most travel corridors around Puget Sound public transit does not move a large enough share of travelers during rush hour to effect traffic congestion. There are, however, public transit options which could be implemented over a wide enough area to provide the convenience and travel times necessary to attract drivers from their car and provide an alternative. Fast and frequent public transit needs to run from where people live to where they work to make a dent in traffic. This means improving hundreds of miles of roads to keep the buses, van and carpools moving over arterial streets in addition to the freeways.
Providing an acceptable public transportation option for a significant fraction of Puget Sound residents is possible assuming we stop squandering our transportation funds on $200 to $600 million per mile Light Rail Systems and instead spend it on $2 to $20 million per mile road and bus route improvements which extend to all of our most congested roadways. The alternative is gridlock, which many of us already face, on top of sky high transportation taxes devoted to moving a tiny fraction of our express bus commuters to a train for some portion of their daily journey.
