- There are five possible routes from Shoridan to Mythaca with the following linkperformance functions:t1 = 18 + 4.5x1t2 = 21 + 7.0x2t3 = 26 + 4.9x3t4 = 29 + 3.4x4t5 = 34 + 0.3x5where ti is in minutes and xi is in 1,000 vehicles per hour.a) It is expected that 8,300 vehicles will be making the Shoridan- Mythaca trip in the maximumflow hour, determine the equilibrium flow on the five routes? Will all five routes be used?b) A transportation planner in Mythaca has tried to convert the expected flow and the linkperformance functions above into route floes. His solution includes x1 = 3.50, x2 = 2.82, and x3 =1.58. Do these values seem correct to you?arrow_forwardVS Arrow Diagrams 12.
