HIKI TO DOSHITENOJON DENo.Date3A parking facility operates from 8 a.m. to 6p.m,whereby 20% of those who wish to park are turnedback daily because of lack of space. A total of 200.vehicles are able to park daily of which 60% parkfor an average parking duration of 9 hours and theremaining park For an average parking duration of2 hours. From a survey of the vehicles who arenot able to park daily it is known that 20% ofthese vehicles desire to park for 9 hours and theFor 2 hours.remaining desire toParkIf the parking efficiency is 0.9, determine:Li) the number of additionalspacehours required?(ii) the additional number of parking bays required inorder to meet excess demand?

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.
Calculate green split for each approach (Eastbound, Westbound, Northbound, Southbound) using Webster method. Given: Two through lanes and one left turn lane; Saturation Flow Rate: Through = 1,900 veh/hr/ln and Left turn = 900 veh/hr/ln. Total lost time = 4 seconds.
Vehicles arrive at an entrance to a recreational park. There is a single gate (at which all vehicles must stop), where a park attendant distributes free brochures. The park opens at 8:00 AM. At which vehicles begin to arrive at a rate of 480 veh/h. After 20 minutes, the arrival flow rate declines to 120 veh/h and corrtinues at that level for the remainder of the day. If the time required to distribute the brochure is 15 seconds, and assuming D/D/1 queuing (a) draw the queuing diagram (b) describe the operational characteristics of the queue (maximum queue length, maximum queuing time, average queuing time per vehicle etc.)
TRANSPORTATION ENGINNERING-TRAFFIC SIGNALS An approach to a predetermined signal has 25 seconds of effective green for a 60 second cycle. The approach volume is 500 vehicles/hour and the saturation flow rate is 1400 vehicles/hour. Calculate the average vehicle delay using D/D/1 queing.
The saturation flow for an intersection approach is 3600 veh/h. At the beginning of cycle no vehicles are queued. The signal is timed so that what the queue is 13 vehicles the effective green begins. If the queue dissipates 8 seconds before the end of the cycle and the cycle length is 60 seconds. What is the arrival rate assuming D/D/1 queuing?

Supposed vehicles arve at a signalized road intersection at an average rate of 360 vehhr and the cycle of the trac light is set at 40 seconds. In what percentage of cycles wil the number of venices be amring: 2.1. Exacty 5 2.2. Less than 5 If, after the lights change to green, there is time to clear only 5 venices before the signal changes to red again, what is the probabilty that waiting vehicles are not cleared in one cycle?
