Green Bike Lanes Come to Seattle--New Color Used to Raise Motorists* Awareness of Bicyclists

SEATTLE-SDOT crews took advantage of a break in the weather yesterday (Tuesday, May 6) and installed Seattle's first green bike lanes at two locations. The first location is at Dexter Avenue North, just north of Denny Way. The second location is at East Greenlake Way North, just north of North 50th Street.

Green bike lanes are put in existing bike lanes to raise motorist awareness of bicyclists at points where their paths cross. The cities of Chicago and New York, as well as the state of Vermont are also experimenting with green bike lanes as a way to reduce auto and bike incidents.

At Dexter, the green bike lane was installed on the northwest corner of the intersection where right-turning motorists must cross the path of southbound bicyclists going straight.

At East Greenlake Way North, the green lane was installed on the northwest corner of the intersection in a triangular area to the left of the right-turn lane where motorists might not expect to see bicyclists.

For schematics of the two locations, see http://www.seattle.gov/transportation/greenbikelanes.htm

The material used in the bike lanes is a green construction material that is glued to the pavement. SDOT has tested the product since last June and found it to be a very durable, non-slippery surface. Thanks to Bridging the Gap, Seattle*s transportation levy, green bike lanes will be installed at about a dozen locations over the next three years. The green lanes are expected to contribute to Seattle's goal of increasing bicyclist safety and reducing the rate of crashes by one third between 2007 and 2017.

The next green bike lane that SDOT crews will install will be located at Fremont Avenue North and North Florentia Street, at the south end of the Fremont Bridge and is tentatively scheduled for 9 a.m. Friday morning, but could change depending on the weather. (Note to reporters: please call Friday morning to confirm.)


there's a lot of positive beta surrounding use of colored pavement treatments at high conflict points. NCHRP's recent report "Guide to reducing Colissions involving bicyclists" had a pretty positive analysis of them.

They're pretty darned effective here, Bek. :)

Yeah, they are effective if used well. But did you take a look at that schematic? I don't think the length of lane for both sites (oooooh, a whole two in the city!) is much longer than 100 meters combined.

Generally speaking, they only color points of conflict. Those can actually be pretty short.

I agree. These bike lanes are at "choke points", and that is all that is needed.
Generally, I'm against bike lanes. They send the wrong message to motorists, who will get the idea that bikes are only to ride in bike lanes, and not outside them.

naw. seattle only has 4% bike laned streets (great on arterial routes) so motorists are most definetly accustomed to seeing bikes on the other 96% of city streets.

motorists in seattle emphatically do not think bikes are allowed to only ride in bike lanes. well, except maybe the ignorant people!

I just hope the green bike lanes do not give cyclists a false sense of security.
