Xulosa: Marshrutlarning hech birida normada ruxsat etilgan ushlanish kattaligi oshib ketmagan, shunday ekan, ko‘rilayotgan butun tarmoq ishlash qobiliyatiga ega.
2-qadam. Kadrlararo intervalning qisqarishini hisoblash
16 + 8 + 2 = 26 bi; 96 – 26 = 70 > 47 bi

10,5 + 8 + 2 = 20,5 bi; 96 – 20,5 = 75,5 > 47 bi
16 + 2 = 18 bi; 96 – 18 = 78 > 47 bi
10,5 + 2 = 12,5 bi; 96 – 12,5 = 83,5 > 47 bi
Xulosa: Marshrutlarning hech birida normada ruxsat etilgan ushlanish kattaligi oshib ketmagan, shunday ekan, ko‘rilayotgan butun tarmoq ishlash qobiliyatiga ega.
