At an intersection of two major roads in a metropolitan city, the design speed is 36 kmph and the width of roads is 10 m. If rate of deacceleration and perception reaction times are 5m/s² and 1 second respectively, then inter-green period is [Take vehicle length = 5 m] (a) 2.4 sec (c) 4.8 sec (b) 3.5 sec (d) 8.4 sec
The length of a highway is 550 m when a head-on vehicle collision occurred. Police reports show that neither human error nor vehicle malfunction was the cause of the collision. Check if the length of the highway is sufficient for an overtaking maneuver. *Accident Report: Speed of Overtaking Car = 96 kph, Speed of Overtaken Car = 88 kph, Perception-reaction Time = 2.5 sec, Average acceleration = 2.4 m/sec2, Time of the passing vehicle occupying the left lane = 10.4 sec, Distance between the passing vehicle at the end of its maneuver and the opposing vehicle = 84m.

Traffic on a freeway gives a Greenshield's traffic flow relationship expressed as: Q = 60k-0.16667k? 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
TRANSPORTATION CLASS ASSIGNMENT 1. The traffic flow on a highway is ql=2000 veh/hr with speed of vl=80 km/hr. As the result of an accident, the road is blocked. The density in the queue is k2=275 veh/km. (Jam density, vehicle length = 3.63 meters). Find: (a) The speed of the vehicles at jam density (b) The rate at which the queue grows (in units of vehicles per hour )

Civil Engineering The number of accidents has been recorded at an intersection in the last three years as follows: 18, 21, and 19. The accidents were mostly due to left-turning vehicles, speeding, and the absence of left-turn protection. The average ADT for the last 3 years is 8500. The following shows the crash reduction factor for various countermeasures: Reduction Factor Countermeasure Retime signals Provide left-turn signal phase Reduce speed limit on approaches Provide turning guide lines Prohibit left turns 0.10 0.30 0.35 0.05 |0.75 a) Determine the appropriate countermeasures b) Determine the expected reduction in crashes if the countermeasures are implemented. The ADT is expected to increase 2% Neat work please
