Traffic on a freeway gives a Greenshield's traffic flow relationship expressed as: Q = 60k-0.16667k² At 10AM, an accident occurs 4 km downstream of an access ramp. The vehicles pull onto the shoulder of the roadway, but traffic passing the accident area slows to 10 kph as drivers survey the damage on the side of the road. A patrol car enters the freeway via access ramp, also at 10AM. Upon entering the freeway, the patrol car notes that traffic on the freeway is moving along at about 40 kph. Determine the following: 1. Capacity flow of the highway 2. Traffic shockwave created by the road accident 3. Time in AM the patrol car will reach the accident zone 4. Plotted traffic shockwave line in the Q-k traffic model diagram

The free flow speed of vehicles on a road section is considered as 80 km/hr and jammed density as 240 veh/km. Estimate the i) traffic density on the road section in maximum traffic flow conditions, ii) possible maximum flow rate for the road section, and iii) average speed of the vehicles at the maximum traffic volume.

The following 10 vehicle speeds (in mi/h) were in measured on a roadway segment: 60, 65, 64, 71, 66, 65, 59, 63, 72, 71. The space mean speed for this data set is: O 65.0 C 65.3 65.6 Insufficient information is provided. O None of the above
Assume that the speed-density function of a section of highway follows Greenshield's Model. The free-flow speed is 75 mph and the jam density is 176 veh mi lane a. Derive V as a function of S. b. In 15 minutes, you have counted that V=150 veh 15 minute lane Estimate the two possible speeds S (in mph) during this 15 minute period.
A section of highway having a length 60 m. The observed data are 6 vehicles cross over it in a period of 148 sec., for the following duration: 2.4, 2.8, 3.0, 2.1, 2.2, and 3.5 sec. Estimate the values of the flow rate, density, space-mean speed, time-mean speed, average gap, and average clearance. If the length of vehicles are 6, 5.4, 6.6, 4.8, 7.5, and 6 m respectively?
Data obtained from aerial photography showed six vehicles on a 600 ft – long section of road. Traffic data collected at the same time indicated an average time headway of 4 sec. Determine (a) the density on the highway, (b) the flow on the road, and (c) the space mean speed.
A freeway traffic stream was observed to have a density of 22.0 veh/mi/ln when the mean speed was 55.0 mi/h. On another occasion at the same location, the jam density was found to be 132 veh/mi/ln. Assume Greenshields' model of traffic flow applies. The flow rate (in veh/h/ln) at the time when the mean speed was 55.0 mi/h is: 990 1210 1540 2178 None of the above

Problem.
A simple four-legged intersection needs a fixed-time signal. The critical lane flows in the N-S and E-W directions are 950 and 600 veh/hr/ln, respectively. Saturation flow is 1,950 veh/hr/ln and the lost time per phase is 6 seconds. Assume yellow interval is 3 seconds and all red interval is 2 seconds. Determine the cycle length and the distribution of green using Webster’s method.
A Four Lane freeway is located on rolling terrain with a free flow speed of 70 mph,12ft lanes, and no lateral obstructions within 8 ft of the pavement edges. the traffic stream consists of cars, buses and large trucks (no recreational vehicles) .
