Assume the following saturation flows:
Through lanes: 1760 vehIn/h
Through and right lanes: 1540 veh/In/h
Left lanes: 1100 veh/n/h
Left and through lanes: 1320 veh/in/h
Left, through, and right lanes: 1210 veh/n/h
A signalized intersection approach has an upgrade of 4%. The total width of the cross street is 60 ft. The avg. vehicle length is 16 ft. Traffic operates at 40 mph. Find the min. change and clearance interval (CCL).
