TransportationCommission | 2011-12-14 | 4 | what Lucy said. Alameda has every pre-qualification to be a world famous bicycle-friendly community yet the City needs infrastructure to match it. He had three points: 1) On the class I bike paths on page 4 - He would like to see 12 feet as the recommended minimum because these paths become multi-use paths. Twelve feet accommodates multiple conflicts, users, directions and speeds. Twelve feet should be the floor and should be the minimum for each side of the west span of the Bay Bridge. Golden Gate Bridge is ten feet and seems too narrow. 2) On Page 34 regarding in-street bike corrals, earlier in the year we had conversations about having them in front of businesses such as Stones Cyclery even on a trial basis. Park Street is going to need more bike parking due to the elimination of the parking meters along Park Street totaling about 100 de-facto bike parking spaces. 3) Class II bike lanes - such as Central Avenue between Willow Street and Oak Street is 5.5 feet - if you recommend an effective door zone of five feet between the bicycle tire and the parked car to allow for sudden doors to be opened, then need to place bicycle tire on the bike lane line on the Central Avenue bike lane. It says something about the current practice as three feet yet they are talking about changing it nationally because the average door on an SUV is four feet when open. Bicyclists need one foot between the door and the bicycle to ensure that the bicyclist is predictable and safe. He recommends an increase in the width of bike lanes and at least a four-foot door zone. Commissioner Tribuzio asked about loop detectors and if they are the same as the ones at intersections for vehicles. Staff Khan replied that loop detectors detect the metal of a car and staff increases the sensitivity to detect bicyclists. Cameras are becoming more common such as on Webster Street and eventually on Park Street to ensure better detection of bicyclists. Commissioner Tribuzio asked about bicycle racks. The guidelines showed two kinds - U shaped and the ring kind. He questioned if it would be cheaper to use the ring kind for construction. Page 4 of 9 | TransportationCommission/2011-12-14.pdf |
