I'm registered for next Saturday's New Jersey Bicycle Summit. The theme is "Complete Streets", and will include both presentations and workshops. Attendees include engineers, transportation planners, government planners, cycling (and pedestrian) advocates, cycling clubs, and just-plain-interested-cyclists.
I'm aware of a number of key issues (lane width/shared-use lanes, aggressive motorists, poor road maintenance, narrow cycle lanes, cycle lanes in door zones, encroachment of cycle lanes by other traffic and parking, cyclists who are unfamiliar with cycling laws -- usually immigrants delivering take-out or kids practicing stunts, varying speeds/needs of cyclists, non-existent or unsafe shoulders, safety of parked/locked bicycles, etc.) but would be interested in knowing if there are others I missed, or which might directly affect you.
Also -- for those of you who avoid bicycle lanes when they are available and along the route for your workout/commute/errands/training, what are your reasons for avoiding them?
