transportation engineering Two highways connect an origin-destination pair, having performance functions t1 = 5 + 4(x1/01) and t2 = 4 +5(x2/2) for routes 1 and 2, respectively. For the performance functions, the t's are in minutes, and the flows (X's) and capacities (C's) are in thousands of vehicles per hour. The total traffic demand for the two highways is 3,036 vehicles during the peak hour. The capacities of routes 1 and 2 are 3600 veh/h and 4500 veh/h, respectively, Determine...
Two routes connect an origin and destination with performance functions t1 = 5 + 3x1 and t2 = 7 + X2, with t's in minutes and x's in thousands of vehicles per hour. Total origin-destination demand is 7000 vehicles in the peak hour. Traffic is consisted of 6100 passenger cars (each with two 2-kip single axles), 800 buses (each with two 2-kip single axles) and 100 heavy trucks (each with one 12-kip single axle and two 34-kip tandem axles.) How...
(iii) [14 marks] Consider a simple network between a single OD pair (from zone A to zone B), with travel time functions Travel time functions: Link 1 Link 3 Link 2 t1 = 1 + 0.5x1 t2 = 3 + x2 t3 = 2 + x3 t4 = 3 + 2x4 Link 4 Figure 2 Transportation Network In which xị, i = 1,2,3,4 are the link flows. The OD demand from A to B is D = 15 units. Solve...
A is covering the words provide and time B is covering the word equal C is covering the words this and each D is covering the word fraction Homework Assignment #5: Route Choice The network below represents the available paths for the vehicles from A to D. The travel time functions for all links are given below, where is the travel time (in minutes) from node to node and is the flow (in vehicles per hour) from node to node...
