- On a specific westbound section of highway, studies show that the speed-density relationship is: It is known that the capacity is 5200 veh/h and the jam density is 310 veh/mi. What is the a.) space-mean speed of the traffic at capacity, (mph) b.) and what is the free-flow speed? (mph)Using Greenshields' model, for a highway with a mean free flow speed of 76 mi/h and jam density of 128 veh/mi, determine the density (in veh/mi) when the mean speed is observed to be 58 mi/h:Topic: Transportation engineering Free-flow speed of a lane of a road is 120 km/h and the jam density is 80 veh/h. Prove that the maximum flow will be 2 400 veh/h
- Traffic flow on a four-lane (one direction) freeway can be described by the Greenshields model. Two lanes of the four lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hr. The mean free speed of the highway is 60 mi/h and the jam density is 140 veh/mi/ln. If it is estimated that the demand flow on the highway during the emergency repairs is 80% of the capacity, using the deterministic approach, determine: (a) The maximum queue length that will be formed (b) The total delay(c) The number of vehicles that will be affected by the incident(d) The average individual delayOn a freeway with a flow of 1600 vehicles per hour and an absolute maximum space mean speed of 110mph, the following point speeds were observed (in mph): 52,48,58,43,58,54,62,51,58,55,59,59,53,50,54. Determine the jam density, in vehicles per mile.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. Calculate the jam density (veh/mile).
- A one-way road is found to have a capacity of 2000 veh/hr. If a traffic enforcer says thatt thetraffic 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.What would be the capacity of the highway if the jam density 200 veh/km, and having a flow rate of 500 veh/hr whebn density is 155 veh/km?Find the accident rate at a road intersection per million entering vehicles if the average daily traffic is 348 and 1769 accidents had occured in the last 3 years. Express your answer in whole number.

(Veh/km and 3 decimals)Find the accident rate at a road intersection per million entering vehicles if the average daily traffic is 325 and 1,766 accidents had occurred in the last 5 years. Express your answer in whole number.Given a freeway flow study at a certain highway. The speed- density relationship is described in thegiven equation or relationship:V s = 60- 0.48kDetermine the following:a. Free-flow speed and jam densityb. Derive the equation describing flow and speed.c. Derive the equation describing flow and density.d. Determine the capacity of highway
