traffic signal not triggered by bicycle
North Grimmer at Paseo Padre
At the completely reconstructed Grimmer/Paseo intersection near the water park, there's now a bike lane on Grimmer for cyclists turning left onto Paseo Padre. There's no "sweet spot" marker in that bike lane, and we were unable to trigger a green light with our bicycles. (There's also no longer a crosswalk on the southeast side of the intersection, so we couldn't fall back to pressing the ped button as a workaround.) A few minutes later, some cars arrived in the left-turn lanes and immediately triggered the signal.
Since this is a new signal, it should be detecting bicycles:
AB 1581 added the following provisions (among others) to the Vehicle Code:
21450.5. (b) Upon the first placement of a traffic-actuated signal or replacement of the loop detector of a traffic-actuated signal, the traffic-actuated signal shall, to the extent feasible and in conformance with professional traffic engineering practice, be installed and maintained so as to detect lawful bicycle or motorcycle traffic on the roadway.
(c) Cities, counties, and cities and counties shall not be required to comply with the provisions contained in subdivision (b) until the Department of Transportation, in consultation with these entities, has established uniform standards, specifications, and guidelines for the detection of bicycles and motorcycles by traffic-actuated signals and related signal timing.
The standards, specifications, and guidelines have been established and were incorporated into the California MUTCD (effective with Traffic Operations Policy Directive 09-06 on September 10, 2009):
Section 4D.105(CA) Bicycle/Motorcycle Detection
All new limit line detector installations and modifications to the existing limit line detection on a public or private road or driveway intersecting a public road (see Section 1A.13 for definitions) shall either provide a Limit Line Detection Zone in which the Reference Bicycle-Rider is detected or be placed on permanent recall or fixed time operation. Refer to CVC 21450.5.
