There are five middle schools on and north of 47th street. All intersections must be measured with 9th Avenue and 10th Avenue .
47th Street and 48th Street between 8th and 9th Avenues are used by the firetrucks coming and going to the fire station on 8th Avenue and 48th . Both streets need to be measured for queues and gridlock and techniques must be devised to give priority to the fire trucks.
Indeed tour buses are a major nuisance on all cross streets.
