A few weekends ago, I forgot to check the construction and traffic alerts before getting in my car and got stuck in one hell of a traffic jam on Aurora Ave N, headed south toward downtown Seattle from Greenwood. Highway 99 was closed from Valley through the Battery Street Tunnel yet I, unaware of what was going on, failed to plan and drove right into an complete standstill, made worse by the difficulty of exiting the road south of the exit to Dexter.
Maybe such a failure of planning is to be expected for some portion of normal drivers. But when I came home and checked how the bus routes on Aurora were being rerouted I was surprised to see they were staying on 99 all the way down to Valley! That’s several trips per hour, on routes that use Aurora for its speed, moving few people very slowly. Watching King County Metro and the state and city transportation departments fail as badly to plan as I did was hard to take.
When severe congestion makes transit severely unreliable, people who absolutely must get where they’re going are more likely to drive, making the congestion even worse. People considering optional trips are more likely to stay home, causing economic impacts in the area and generally frustrating people’s desires, making them less happy. Mass transit has the ability to use road space very efficiently, to provide more trips with less congestion. But people have to be willing to take it; there has to be an incentive.
This is, of course, the reason we’ve added bus lanes on Aurora and parts of 520, and will be adding more. It’s the reason we need to add bi-directional bus lanes on I-5 all through Seattle, and on the route the West Seattle buses will take after the Viaduct comes down. And it’s the reason we need bus lanes through construction zones.
That weekend there was a hard bottleneck at Aurora and Valley and only a limited number of vehicles could get through. But if we had maintained a bus lane all the way through the bottleneck we could have made the most of that limited number of vehicles. We didn’t. It was miserable. And we aren’t, by any current plans, going to maintain bus lanes through the long-term bottleneck caused by Mercer West construction, and that will be miserable, too.
