---------------- civil engineering ----------------------- capacity 1500 veh/h free flow speed 60 km/hr on a one lane traffic road, there exists a railway grade grossing at the end of the road section. on one day, a train is passing through the crossing and the gate is cloased. consequently the vehciles are required to stop behind the gate while the train is passing. three min later the gate opens and the vehicles leave rigth away. traffic flow in normal traffic conditions is...
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...
6, Traffic Shockwave theory (15%) Vehicles approaching an signalized intersection are traveling at speed 40 miles per hour and the density is about 40 vehicle/miles/lane (vehicle arrival). The red light last about 40 sec. If the saturation flow is 1900 vehhr/lane with a density of 52 veh/miles/hour (queue discharging). and the jam density is 120 veh/mile lane, please determine: a. the queue length at the end of the red light: b. the maximum queue length: c. The time it takes...
Exercise 1 [I8 pts]. Two lanes of a three-lane highway are closed because of road works on a 2 km long segment. A detector placed on one single lane in the undisturbed zone upstream the road works detects a flow of 2,000 veh/h and an average speed of 100 km/h. A second detector placed on one of the two lanes just upstream the roadwork zone detects a flow of 800 veh/h and an average speed of 40 km/h. We observe...
