Concept explainers

Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

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.

Current Attempt in Progress Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car Pobserves this speed via radar. The driver of car Ais traveling at va - 136 km/h as it passes P, but over the next 5.5 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the canstant rate of 5.3 m/s? until a speed of 151 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Answers i
You are designing an on-ramp that connects an intersection (controlled by a signal) and the highway. You want to assure that vehicles that are completely stopped at the intersection can reach the prevalent highway speed, which is assumed to be 60mph. Assume that passengers have the maximum acceleration rate of 10 ft/sec2 , trucks have smaller acceleration rate 3.2 ft/sec2 . You can assume that vehicles can use the maximum acceleration rate regardless of the speed. What’s the reasonable length for the ramp?
One vehicle is following another on a two-lane, two-way highway at night according to the safe-driving “rule-of-thumb” of one car length spacing for each 10 mph of speed. Both of you traveling at 70 mph when the lead vehicle crashes into an unlighted disable vehicle. Assuming that one car length is 20 feet, f=0.28 and PIEV time is 1.5 for you, will you hit the lead vehicle? If so at what speed will you be going?
A vehicle pulls out onto a single-lane highway that has a flow rate of 300 veh/h (Poisson distributed). The driver of the vehicle does not look for oncoming traffic. Road conditions and vehicle speeds on the highway are such that it takes 1.7 seconds for an oncoming vehicle to stop once the brakes are applied. Assuming a standard driver reaction time of 2.5 seconds, what is the probability that the vehicle pulling out will get in an accident with oncoming traffic?
Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A is traveling at vÃ = 122 km/h as it passes P, but over the next 4.1 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.0 m/s² until a speed of 164 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Answer: s= i VA 248.52 P m

Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A is traveling at VA = 128 km/h as it passes P, but over the next 5.8 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 5.9 m/s² until a speed of 168 km/h is achieved, and that speed is then maintained.
