TransportationCommission | 2009-04-22 | 6 | DRAFT would be a 10% reduction in the wait time; they were not suggesting taking it back to a level it was decades ago. Staff Khan stated staff's understanding that the Commission had asked to see what happens if the intersection was brought to LOS B. Commissioner Krueger referred to page 24 under mitigation 3.6, stating that mitigations 3.1 to 3.6 suggested that pedestrian LOS D was more feasible to maintain at all intersections. Chair Knox White noted the report stated LOS D for pedestrians would prevent mitigations. Seemed that the City's goals were to have something so low that we would never have to mitigate it; D was the way to go. Staff Khan referred Chair Knox White to Mitigation 4.4. Chair Knox White responded that if D was chosen, there would be no problems for pedestrians. Staff Khan agreed. Staff Bergman mentioned the Commission's comments from the last meeting, that the removal of marked crosswalks should be considered to be a significant impact. Staff agreed and supports that the inclusion of that in the thresholds. Chair Knox White asked Nathan Landau from AC Transit if the recommendation suited the LOS AC Transit wanted. Mr. Landau replied AC Transit asked to try and maintain LOS C to maintain a reasonable speed, and define a segment by the five bus stops. Stated that the off-site impact was worth addressing, looking at a place where there is an auto impact and 10% degradation in speed. Ideally, the threshold would be a 10% reduction in speed even if it were operating at LOS B. Chair Knox White referred to the report stating the need to keep average speed up along the routes. The Dowling study mentioned corridor #10, Robert Davy Jr. Drive had a LOS B, as well as Island Drive; 3/4 of the analysis was LOS B. Inquired if a decrease in travel speed from 23 mph to 13 mph before it was considered an impact would be acceptable to AC Transit. Mr. Landau recommended previously that any transit average travel speed over the effected segment would be reduced by 10% or more. That was recommended to staff irrespective of the existing level of service; he noted that Line 51 is currently not doing better than C. Chair Knox White inquired if AC Transit would ever have its own policy on this matter. Mr. Landau replied possibly; planning on revising their guidelines within the next 18-24 months. Chair Knox White inquired if in two years we may end up with a 10% degradation. Mr. Landau replied that the average travel speed had dropped system wide to 11 mph, so it costs more to operate same service; also passengers don't want slow buses. AC Transit is working on bus rapid transit, queue jumps, signal timing to protect travel times. Page 6 of 15 | TransportationCommission/2009-04-22.pdf |
