<6 ß" 2- (mph), with a "critical" or 85th-percentile speed of approximately 35 mph. Þ- The posted speed limit is 30mph. The traffic volume on Hopkins Avenue is approximately 7,500 vehicles per day, with 750 vehicles during the PM peak hour. Þ- King Street carries approximately 90 vehicles during the PM peak hour at the intersection. Þ- Approximately 20 pedestrians were recently observed crossing Hopkins Avenue at King Street during two hours from 4:00 to 6:00 PM on a summer weekday; an additional 20 pedestrians crossed Hopkins Avenue at Lowell Street during that period. This time period was observed because it corresponds with the highest volume of conflicting vehicle traffic on Hopkins. Þ- The number of pedestrians crossing is probably significantly higher on weekends, as reported by neighboring residents. Staff also estimated traffic delay and queue lengths at the intersection during the PM peak hour. The current average delay on King Street at the existing 2-way stop sign is 12 to 13 seconds per vehicle. Projected average delay on westbound Hopkins Avenue (the traffic direction with the highest volume) with a 4-way stop would be 15 seconds per vehicle. The projected queue length on westbound Hopkins Avenue with a 4-way stop would average three to four vehicles, with occasionally up to seven to eight vehicles. If the future traffic volume increases by 10%, the projected average delay on westbound Hopkins Avenue would be 18 seconds, and the projected queue length would average four vehicles, with occasionally up to 8 vehicles, with a 4-way stop. These existing and projected delays are all considered acceptable according to usual City standards. Stop signs would increase the level of noise and exhaust emissions for immediately adjacent residents, and the effect on the traffic flow pattern and queues would increase the difficulty of entering and exiting adjacent driveways during peak traffic hours. Installing stop signs on Hopkins Avenue at King Street could possibly attract more traffic to use King Street as a north-south route, as it already has the advantage of 4- way stops at Brewster and at Whipple Avenues. King Street is a primary Fire Department emergency response route, and adding the stop signs on Hopkins Avenue would enhance fire equipment movement through the intersection on King Street. However, Hopkins Avenue is also a primary response route that connects toward Sequoia Hospital, and adding stop signs on Hopkins Avenue could slow emergency vehicle movement through the intersection on Hopkins Avenue. 3. Conclusion The Hopkins Avenue/King Street intersection does not meet the engineering criteria for installation of a 4-way stop according to City policy. The reduced stop sign warrants adopted by the City 2 years ago (attached) apply to residential local streets and minor collectors with a maximum volume of 4,000 vehicles per day. Hopkins Avenue at King Street does not qualify, since it carries a volume of 7,500 vehicles per day. Therefore, the intersection is subject to the more rigorous Caltrans Traffic Manual warrants for a 4-way stop installation.
