Assume an origin is connected to a destination with two routes.
Assume the travel time of each route has a linear relationship with
the traffic flow on the route. Determine when tolling cannot reduce
the total travel time of the two routes.

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...

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 are under consideration for new highway. The northerly route X would be located about 5 miles from the central business district and would require longer travel distance by local commuter traffic. The southerly route Y would pass directly trough the downtown area and, although its construction cost would be higher, it would reduce the travel time and distance for local commuter. Assume the cost for two route are as follow : Route X Route Y Initial cost Maintenance...

Dorothy Stanyard has three major routes to take to work. She can take Tennessee Street the entire way, she can take several back streets to work, or she can use the expressway. The traffic patterns are, however, very complex. Under good conditions, Tennessee Street is the fastest route. When Tennessee is congested, one of the other routes is preferable. Over the past two months, Dorothy has tried each of route several times under different traffic conditions. This information is summarized...

PLEASE SHOW WORK. WILL UPVOTE WITHIN A DAY.
Part B: Let's consider a town with a low-capacity town route (1500 vehicles per hour) and a high-capacity bypass (3000 v/h), as shown below. The bypass is longer but has higher geometric design standards. Let's assume that during morning peak, 2000 drivers approach the town and all of them want to use the shortest route, i.e. via town center. Not all drivers will be able to use this route, since it would...

DIFFERENTIAL EQUATION PROBLEM
An object with a mass of 2 kg moves along the x-axis and we will
assume that the positive direction of movement is to the right.
Only one force (in N) is present and opposes the movement. Let
be the speed of the object (in m / s) at time t. The object starts
from the origin (x = 0) with an initial speed of 75 m / s. Suppose
that the resistance force has a magnitude...

5. Traffic on Route 15 south of Selinsgrove was observed at two different times. The first observation found a flow rate of 1,863 vehicles per hour per lane and a density of 85 vehicles per mile. The second observation found a flow rate of 1,050 vehicles per hour per lane and a density of 25 vehicles per mile. Using this data, compute the following: a. For both observations, determine the vehicle speed [mph] and the time headway [sec] b. If...
