13. An incident that occurs on a particular highway results in traffic incurring an
average delay of one hour per vehicle. An estimated 2,000 vehicles are impacted by
the incident. If the distribution of traffic is comprised of 5% five-axle trucks, 2%
three-axle trucks, 4% six-tire trucks, 2% four-tire trucks, 4% medium auto for
business purposes, 3% small auto for business purposes, and the remainder are
automobiles for personal purposes, what is the value of the total delay incurred by
the traffic.
2. A one-way road is found to have a capacity of 2000 veh/hr. If a traffic enforcer says that the traffic volume there is only 150
veh/hr, can you conclude that the traffic condition is not congested? Why or why not? Illustrate using a diagram.

- QUESTION 12 One lane of a uniform section of highway has an optimum density of 70 vehicles per mile and an optimum speed of 35 miles per hour. If vehicles are travelling at an average speed of 40 mph, the traffic flow conditions are CONGESTED. O True O Falsearrow_forwardfreeway with two northbound lanes is shut down because of an accident. At the time of the accident, the traffic flow rate is 1200 vehicles per hour per lane and the flow remains at this level. The capacity of the freeway is 2200 vehicles per hour per lane when not impacted by an accident. The freeway is shut down completely for 20 minutes after the accident; then one lane is opened 20 minutes after accident; and finally both lanes are opened 40 minutes after the accident. What is the total delay resulting from the accident (assuming D/D/1 queuing)?arrow_forwardThe French autoroute network is composed of toll motorways with entrances marked as such. A motorist entering the network obtains a ticket from a toll booth and pays a toll when leaving the motorway. Given the number of vehicles traveling these routes, congestion at both entrances and exits is common. Suppose that four groups, each of 50 motorists, use an autoroute. The price each group is willing to pay, v, differs among groups and falls as the amount of congestion, c, increases in the following way: vij=vimax-cj; i, j = 0,..., 3, where vi max = 0.4-0.1 * i euros per kilometer is the maximum group i is willing to pay to use the motorway and cj = 0.06 * j euros per kilometer is the loss in value as more groups use it. The marginal cost of using the autoroute, not including the marginal cost of congestion, is zero. a. If the toll charged for using the autoroute equals a motorist's marginal private cost-the price in a competitive market-how many vehicles per minute will use it? Which…arrow_forward
- The number of accidents for 6 years recorded in a certain section of a highway is 589. If the average daily traffic is 1,476, determine the accident rate per million entering vehicles. Answer in whole number.arrow_forwardOn a highway, we know that on average 260 cars arrive at a toll booth in one hour. If we admit that thenumber of cars arriving at this toll station follows a lawPoisson, calculate the probability that there are less than fourarrived within a minute.arrow_forwardA gasoline service station sees on average 27 arrivals of vehicles every one hour in the morning. The average service time is 100 seconds.

- [T] The following table provides hypothetical data regarding the level of service for a certain highway. Plot vehicles per hour per lane on the x-axis and highway speed on the y-axis. Compute the average decrease in speed (in miles per hour) per unit increase in congestion (vehicles per hour per lane) as the latter increases from 600 to 1000, from 1000 to 1500, and from 1500 to 2100. Does the decrease in miles per hour depend linearly on the increase in vehicles per hour per lane? Plot minutes per mile (60 times the reciprocal of miles per hour) as a function of vehicles per hour per lane. Is this function linear? Highway Speed Vehicles per Hour per Lane Density Range (vehicles / mi) > 60 < 600 < 10 60 - 57 600 - 1000 10 - 20 57 - 54 1000 - 1500 20 - 30 54 - 46 1500 - 1900 30 - 45 46 - 30 1900 - 2100 45 - 70 < 30 Unstable 70 - 200arrow_forwardQuestion. 2Propagation speed of 45 km/hr and that each toll booth takes 6 seconds to service a car.Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth.
