Traffic 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).
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.
