Transportation Engineering-1 During a 70 sec period, a detector is occupied by vehicles for the following times: 0.31, 0.39, 0.41, 0.35, and 0.53 sec.

Trucks: 10%; RVs: 7%; PHF:0.97; directional split: 60/40; no passing zones: 40%.Compute the minimum passing sight distance for the following data: Speed of the passing car = 96 kphSpeed of the overtaken vehicle = 80 kphTime of initial maneuver = 4 secsAverage acceleration = 2.4 kph/secTime passing vehicle occupies the left lane = 9 secsTime the passing vehicle meets the vehicle originally occupying the left lane = 6 secQ3b. The 15km Atta Mills road connecting Old Barrier to Kokrobite operates with a capacity of 2250 pcu/hr and can be traversed within 15 minutes under free flow conditions.

- Studies have shown that the traffic flow on a two-lane road adjacent to aschool can be described by the Greenshields model. A length of 0.5 miadjacent to a school is described as a school zone and operates for a periodof 30 min just before the start of school and just after the close of school.The posted speed limit for the school zone during its operation is 15 mi/h.Data collected at the site when the school zone is not in operation showthat the jam density and mean free speed for each lane are 125 veh/mi and57 mi/h. If the demand flow on the highway at the times of operation ofthe school zone is 90% of the capacity of the highway, determine: The speeds of the shock waves created by the operation of the schoolzone, and• The number of vehicles affected by the school zone in the upsream ofthe zone during this 30-minute operation.Assume that passenger car equivalents are 1.5 for trucks (ET), 1.6 for left-turns (EL), and 1.4 for right-turns (ER), and saturation flow qs= 160 x (curb-to-curb width / # of lanes) equivalent passenger-car units per hour per lane (pcu/hr/ln). Pedestrian walk speed (PS) is 4 ft/sec, and the effective width of crosswalk (WE) is 9 ft. Given that the intergreen time is 8.0 seconds and lost time is 3.5 seconds per phase, design a 2-phase signal timing plan using the Webster’s method.A signalized intersection has four approaches.
