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?

A car is approaching toward an intersection with speed 45 mph. The road has a downhill grade of 1%. When the car is at a distance of 250 ft from the intersection, the signal turned yellow. If the driver applies brake and the reaction time of the driver is 1.5 s, will the driver be able to come to a complete stop? Justify your answer with calculations. Assume braking friction coefficient of 0.35.
A van is driven at 60 km/h and is brought to a full stop with constant deceleration in 7seconds. If the total car and driver mass is 1.825kg find the necessary force.
An auto, equipped with only front wheel brakes, has a wheelbase of 120 in. with its c.g. located 60 in. ahead of the rear wheels and 36 in. above the pavement. If f = 0.80 at the tires, compute the minimum distance in which the auto can be brought to rest from a speed of 60 mph if the driver’s reaction time before applying the brakes is 3/4 sec.
A motorist travelling at 100 km/hr on a highway needs to take the next exit, which has a speed limit of 50 km/hr. The section of the roadway before the ramp entry has a downgrade of 3% and coefficient of friction (f) is 0.35. In order to enter the ramp at the maximum allowable speed limit, determine the braking distance (expressed in m) from the exit ramp.
Traffic flow shows the magnitude of the vehicle headway on average 2.2 seconds at a speed of 50 km/hour. Calculate the density and flow rate for this traffic flow.
Six vehicles are observed in a 200 m section of a highway. If the average time headway is 4 sec., determine the density of flow (veh/km), flow of traffic (veh/hr) and space mean speed (kph).
A car is traveling at 76 mi/hr down a 3% grade on poor, wet pavement. The car's braking efficiency is 90%. The brakes were applied 320 ft before impacting an object. The car had an antilock braking system, but the system failed 200ft after the brakes had been applied (wheels locked). What speed was the car traveling at just before it impacted the object? (Assume theoretical stopping distance, ignore air resistance, and let Frl=0.015)
A section of highway has a speed-flow relationship of the form q = a*u*u + b*u (a and b are coefficients to be determined). It is known that at capacity (which is 3100 veh/h) the space-mean speed of traffic is 35 km/h. Determine the speed when the flow is 1500 veh/h and the free-flow speed.
Assume you are observing traffic in a single lane of McArthur Highway at a specific location. You measure the average headway and average spacing of the vehicles as 3.2sec. and 50 m. respectively. Determine the traffic speed in kilometer/hour
Traffic is observed at a single lane of a highway at a specific location. The average headway and average spacing of passing vehicles are measured as 3.5 seconds and 192 ft., respectively. Calculate the average speed (mph), flow (veh/hour), and density (veh/mile) of the traffic stream in this lane
The car is traveling at a speed of 75 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 7.4 ft/sec2 until it gets to point B, after which its constant rate of decrease of speed is 3.7 ft/sec2 as it rounds the interchange ramp. Determine the magnitude of the total car acceleration (a) just before it gets to B, (b) just after it passes B, and (c) at point C.
