Loads and Reactive Forces

Loads are the external influences that a beam experiences under its working conditions. For instance, a beam may be subjected to shear loads, twisting loads, bending moment, and axial loads during its working conditions. Engineers primarily deal with beams and trusses in the civil engineering domain. Due to the influence of loads, it is very crucial to determine the induced stresses and deformation values. These values give an insight into the critical area of the beam that needs to be worked upon to make it fail-safe.

An incident occurs on a freeway that has a capacity in the north bound direction, before incident, of 4000 veh/h and a constant flow of 2900 veh/h during the morning commute (no adjustments to traffic flow result from the incident). At 8:00am, a vehicle crash closes the freeway to all traffic. At 8:12am, the freeway is partially opened with a capacity of 2000 veh/h. Finally, the crash site is removed and the freeway is restored to full capacity of 4000 veh/h at 8:31am. Assuming the traffic follows a D/D/1 queueing (FIFO queue discipline) to determine time of queue dissipation, longest queue length, total delay, average delay per vehicle, and longest wait of any vehicle.
Example 3 Because of a minor collision, one of the two SB lanes on a freeway is blocked at 8:13am. The normal freeway capacity of 3600 vph is reduced to 1340 vph. The SB flow rate at this time of day is 2715 vph. The blockage is removed after 15 minutes. - Find the maximum queue length Maximum time spent in queue - - - Time of queue dissipation - Total delay -
A freeway with two northbound lanes is shut down because of an accident. At the time of theaccident, the traffic flow rate is 1200 vehicles per hour per lane and the flow remains at this level.The capacity of the freeway is 2200 vehicles per hour per lane when not impacted by an accident.The freeway is shut down completely for 20 minutes after the accident and then one lane is openfor 20 minutes and finally both lanes are opened (40 minutes after the accident). What is theaverage delay per vehicle resulting from the accident (assuming D/D/1 queuing)?
Subject: transportation engineering Read the question carefully and give me right solution according to the question. A signal has four phases, where the critical lane group flow ratios are 0.115, 0.204, 0.099, and 0.248. If the lost time per phase is 6 seconds and the critical intersection v/c ratio is 0.88, calculate the minimum cycle length and the phase effective green times such that the lane group v/c ratios are equal.
In signal design as per Indian Roads Congress specifications, if the sum of the ratios of normal flows to saturation flow of two directional traffic flow is 0.50 and the total lost time per cycle is 10 seconds, the optimum cycle length in seconds is
2cb) The average speed of a 1st group of vehicles over a road msegment is per 45 km/h and their flow is 1350 vehicles hour.

SEAT WORK: EA4 Queving theory: D/D/1 Vehicles arrive at an entrance to a recreational park. There is a single gate (at which all vehicles must stop), where a park attendant distributes a free brochure. The park opens at 9:00 A.M., at which time vehicles begin to arrive at a rate of 470 veh/h. After 20 minutes, the arrival flow rate declines to 115 veh/h, and it continues at that level for the remainder of the day. If the time required to distribute the brochure is 14 seconds, and assuming D/D/1 queuing, describe the operational characteristics of the queue.
Consider the problem of traffic flow on a three-lane (one direction) freeway which can be described by the Greenshields model. One lane of the three lanes on section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take several hours. It is estimated that the capacity at the work zone will be reduced by 30 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 50 mi/h and the jam density is 120 veh/mi/In. It is estimated that the demand flow on the highway during the emergency repairs is 86 percent of the capacity. Using the deterministic approach, determine the following for the expected repair periods of 1 h, 1.5 h, 2.5 h, 2.75 h, and 3 h.

An accident occurs on a one-lane highway and blocks off all lanes of traffic. This freeway has a jam density of 130 veh/mi. Before the accident occurred (and upstream of the queue that forms), traffic was (is) traveling at an average speed of 45 mi/h and density of 30 veh/mi. Assume that the following conditions are present: ● ● Before the queue: Uupstream = 45 mi/h, kupstream = 30 veh/mi After the queue: Udownstream = 60 mi/h, kdownstream = 0 veh/mi Jam Density: kj = 130 veh/mi How long is the queue after 25 minutes?
1) 1) A section of highway has the following flow-density relationship: q-50k-0.156k² What is the capacity (maximum flow) of the highway section, the space mean speed at capacity, and the density when the traffic flow on the highway is at one-quarter of its capacity? 2) An observer has determined that the time headways between successive vehicles on a section of highway are exponentially distributed (arrival of vehicle is Poisson distribution) and that 60% of the headways between vehicles are 13 seconds or greater. If the observer decides to count traffic in 30-second time intervals, estimate the probability of the observer counting exactly four vehicles in an interval.
5. A traffic accident occurred along the North Diversion road at 6:00 AM. The flow rate on the expressway at this time of day was 53 vehicles per min. The normal freeway capacity is 75 vehicles per minute but it was reduced to 21 vehicles per minute due to the traffic accident. The traffic was cleared by the MMDA after an hour minutes. A) Determine the max. length of the queue before the blockage was removed B) Determine the time that the vehicles waited for the long queue before the blockage was cleared C) What time was the queue cleared?
An expressway off-ramp consisting of a single lane leads directly to a tollbooth. The rate of arrival of vehicles at the expressway can be considered to be Poisson with a 6-24 www.Civil08.com - The Download Monster Chapter 6 Fundamental Principles of Traffic Flow 263 mean of 50 veh/h, and the rate of service to vehicles can be assumed to be exponen- tially distributed with a mean of 1 min. (a) What is the average number of vehicles waiting to be served at the booth (that is, the number of vehicles in queue, not including the vehicle being served)? (b) What is the length of the ramp required to provide storage for all exiting vehicles 85% of the time? Assume the average length of a vehicle is 20 ft and that there is an average space of 5 ft between consecutive vehicles waiting to be served. (c) What is the average waiting time a driver waits before being served at the toll- booth (that is, the average waiting time in the queue)?
