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.

Question

A motorist travelling at 104kph on an expressway intends to leave the
expressway using an exit ramp with a maximum speed of 56 kph. At what point
on the expressway should the motorist step on his brakes in order to reduce her

this section of the expressway has a downgrade of 3 percent acceleration is
3.4m/s2.

A multilane highway (three lanes in each direction) is on level terrain. The free flow speed has been measured at 50mph. The peak-hour directional volume is 1500 vehicles with 10% heavy vehicles, and PHF is 0.9. If the proportion of vehicles types and peak-hour factor remains constant, how many vehicles can be added to the directional volume before capacity is reached?
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).
A traffic stream is moving at a steady state when entering a mountain grade. Upon entering the grade, the speed, density and flow are 72 km/h, 25 veh/km and 1800 veh/hr respectively. On the grade, a truck drops to a speed of 15 km/h causing traffic to bunch up to a density of 85 veh/km. When the truck pulls over, traffic accelerates to the maximum flow until steady state flow conditions resume. Calculate (a) the flow of traffic behind the truck on the mountain grade (b) the jam density and free flow speed for this road (c) the density and speed when traffic resumes a steady state flow (d) the maximum flow
2 A slight bend prior to a curve means that a 65 km/h curve advisory speed sign is not visible to drivers until 95 m before the start of the curve. The 85th percentile speed of vehicles on this approach, prior to reaction and braking, has been measured by survey as 88 km/h. If it is assumed that it is desirable for vehicles to slow down to the posted 65 km/h-advisory speed before reaching the curve, what is the required distance to achieve this? Is the available sight distance adequate for this?
A Class I two-lane highway has a base free-flow speed of 110 km/h. Lane width is 3.6 m, and shoulder width is 2.4 m. There are six access points per kilometre. The roadway is located in rolling terrain with 40 percent no-passing zones. The two-way traffic volume is 1000 veh/h, with a PHF of 0.90. The directional split is 70:30. Traffic includes 10 percent trucks and 5 percent recreational vehicles. The length of the analysis segment is 9.5 km. Compute service flow rate for the two-way segment.
Recent computations at an approach to a pretimed-signalized intersection indicate that the volume-to-capacity ratio is 0.8, the saturation flow rate is 1600 veh/h, and the effective green time is 50 seconds. If the uniform delay is 11.25 seconds per vehicle, determine the arrival flow rate (in veh/h) and the cycle length.
Q5 / a. Section road: length = 500 m, average travel time = 90 sec., average running time = 60 sec. and speed limit = 60 Km/hr. Find: fixed and operational delay. Q5 / b. Annual average daily traffic volume = 5000vpd and design hour volume = 750 vpd. Find k – factor and type of roadway. Q5 / c. Four vehicles (5.5, 5.6, 6.4, and 6.5) m long are distributed over length of freeway lane100m. Find Lane occupancy and Density.
A six-lane freeway (three lanes in each direction) currently operates at maximum LOS C conditions. The lanes are 11 ft wide, the right-side shoulder is 4 ft wide, and there are two ramps within three miles upstream of the segment midpoint and one ramp within three miles downstream of the segment midpoint. The highway is on rolling terrain with 10% heavy vehicles, and the peak-hour factor is 0.90. Determine the hourly volume for these conditions in veh/h. Round of your answer to whole number. fLW = 1.9, fRLC = 0.80, PHF = 0.90, N = 3 lanes PT = 0.10, ET = 3.0.
Vehicles arrive at an intersection approach at 550 veh/h at the beginning of an effective red and 15 vehicles are left in the queue from the previous cycle (end of the effective green). Due to peak hour congestion, the arrival rate increases 50 veh/h/min. Therefore after 1 minute, the arrival rate will be 600 veh/h, after 2 minutes it is 650 veh/h. The saturation flow rate of the approach is 1800 veh/h, the cycle length is 65 seconds, and the effective green time is 30 seconds. Determine the total vehicle delay until complete queue clearance. (Assume D/D/1 queuing).
The car is traveling at a speed of 77 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 7.1 ft/sec2 until it gets to point B, after which its constant rate of decrease of speed is 2.3 ft/sec as it rounds the interchange ramp.
