Concept explainers

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.

ANSWER ASAP !!!
A Four Lane freeway is located on rolling terrain with a free flow speed of 70 mph,12ft lanes, and no lateral obstructions within 8 ft of the pavement edges. the traffic stream consists of cars, buses and large trucks (no recreational vehicles) . A weekend directional peak hour volume of 1800 vehicles (*regular users*)is observed ,with 700 arriving in the mostly congested 15 minutes period . if a level of service no worse than C is required ,determine the maximum number of large trucks and buses that can be present in the peak hour traffic stream.. Dislike for wrong answers
Eight lane urban freeway is on level terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of unfamiliar road users. Peak hour volume for a directional weekday of 3200 vehicles is observed with 900 vehicles arriving in the most congested 15-min period. If the traffic stream has 20% large trucks and 20% buses and 15% recreational vehicles, determine the density in pc/mi/In. Round your answer to 3 decimal places. Exclude the unit in the answer box.
A portion of the extension of SLEX has a free flow speed of 60kph and a capacity of 3600 veh/hr. If in a given hour, 3344 vehicles were countered at a specified point along this highway, determine the traffic density of these 3344 vehicles.
There are 9 vehicles observed in a 300 m section of McArthur highway. If the average time headway is 4 sec., compute the space mean speed of the vehicles in kph.
1) A 6-lane two-way arterial road has a maximum flow of 6,000 vehicles per hour on one direction. It is operating at 3,600 vehicles per hour at time, t=0. A collision occurs, blocking the two lanes, and restricting the flow of the outermostlane to 1,600 vehicles per hour. After 40minutes, the police have cleared the middlelane from accident debris; the operating volume at that time increased to 2,400 vehicles per hour.20 minutes past, the innermost lane was finally cleared of the accident. Traffic returns to normalas soon as the queue has already immoderate. a.Determine the maximum length of queue that occurred. b.How long did it take to dissipate the queue? c.If a vehicle entered the road at t=10 minutes, how long will it take for it to leave the traffic?
Eight lane urban freeway is on mountainous terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of familiar road users. Peak hour volume for a directional weekday of 5200 vehicles is observed with 500 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and 12% buses and 10% recreational vehicles, determine the density in pc/mi/In. Round your answer to 3 decimal places. Exclude the unit in the answer box.

Subject : Transportation engineering Give all right solutions. A free flow speed of 60 kph and a capacity pf 3600 vehicles per hour. If in a given hour 3344 vehicles were countered at a specified point along this highway, compute the following A) jam density (in veh/km and 3 decimals) B) space mean speed of these 3344 vehicles. (Kph and 3 decimals) C) density of the 3344 vehicles. (Veh/km and 3 decimals)
The free flow speed of vehicles on a road section is considered as 80 km/hr and jammed density as 240 veh/km. Estimate the i) traffic density on the road section in maximum traffic flow conditions, ii) possible maximum flow rate for the road section, and iii) average speed of the vehicles at the maximum traffic volume.
A multilane highway (two lanes in each direction) is on level terrain. The free-flow speed has been measured at 45 mi/h. The peak-hour directional traffic flow is 1300 vehicles with 8% heavy vehicles. If the peak-hour factor is 0.85, determine the highway’s level of service. Answer: LOS:C
1. A freeway has three lanes in each direction and has a maximum flow of 100 veh/min. It is operating at 50 veh/min. A collision occurs, blocking the two lanes and restricting the flow of the third lane to 25 veh/min. The freeway has a constant speed of 60 veh/hr and its three- lane jam density is 60 veh/m. The incident is completely cleared in 30 minutes and traffic returns to normal as soon this happened. a. Determine the length of queue 20 mins after the collision. b. Determine the longest vehicle queue. 750 veh c. In how many minutes will the queue dissipate? 45 min. So vh.
