Vine Street for NSmovements 1s 48 ft wide and Maple Street for EW movements is 60 ft wide. There are two throughmovement lanes and one left-tum lane in each approach. The yellow times for Vine Street and MapleStreet through movement and left-tum phases are 4 second and 3 seconds per g_hase, respectively. TheAll-red for each phase is 2.0 seconds and the ost time is 5 seconds per phase. Pedestrian walkmgspeed is 3.5 ft/sec.
