- Six vehicles were observed passing a point for every 25 sec. the density of traffic is 30 veh/km. Find the space mean speed.Vehicles at a stop sign require 7 second headway to cross the main street that is located 300 meters downstream from a signalised intersection. If the average flow rate of the main street is 600 vehicle per hour, the min headway is 2.5 seconds and vehicle bunching with 70% free vehicles. What is the probability that a headway will be greater than 7 seconds? O a. 0.105 O b. 0.291 O c. 0.078 O d. 0.204 O e. 0.285Traffic data are collected between Point X and Y. Seven vehicles pass in Point X at intervals of 18, 17, 19, 28, 25, 22, and 24 sec respectively. The vehicle's speeds are 60, 50, 55, 58, 52, 49, and 30 kph respectively. Calculate the flow, density, time mean speed, and space mean speed. Determine also the length of the segment.
- 7.24 Vehicles arrive at an approach to a pretimed signalized intersection. The arrival rate over the cycle is given by the function v(t) = 0.22 + 0.012t [v(t) is in veh/s and t is in seconds]. There are no vehicles in the queue when the cycle (effective red) begins. The cycle length is 60 seconds and the saturation flow rate is 3600 veh/h. Determine the effective green and red times that will allow the queue to clear exactly at the end of the cycle (the end of the effective green), and determine the total vehicle delay for this approach over the cycle (assuming D/D/1 queuing).Observation post reveals that 8 vehicles passed through at intervals of 4.6 s, 6.23 s, 5.9 s, 7.1 s, 4.9 s, 3.8 s, 12.6 s, and 13.0 s, respectively. If the total distance travelled by the vehicles is 200 meters, i. If the density of traffic is 20 vpk, compute the rate of flow of traffic in vph. ii. If the speed limit imposed along the roadway is 100 kph, determine the percentage of speed limit violators.4. Vehicle time headway is 3.5 sec/vehicle and spacing of cars measured at a point along the NLEX, from a single lane of 70 m/vehicle, over the course of an hour. Compute for the traffic density, space mean speed, and the average speed of the traffic.
- Problem 1: There are 12 vehicles observed in a 400 m section of N. Bacalso Avenue. Given that the average time headway is 5 seconds, compute the space mean speed, in kph.The data below shows the result of the flow of traffic at a certain part of a highway by observing the arrival time times for four vehicles at two sections A and B that are 200 m apart. The total observation time at a section A is 20 sec. find the following: a.) time mean speed (kph and in 3 decimals) b.) space mean speed (kph and in 3 decimals) c.) determine the flow at section A (veh/hr and in 3decimals)D. There are 10 vehicles observed in a 450 m length of Aurora Boulevard. If the average time headway is 5 sec. calculate the space mean speed in kph
