A horizontal curve along a two-lane highway with 12-ft lanes is designed with a central angle of 29.93 degrees and a superelevation rate of 8 percent. The station of the PC and PI are 100+00.00 and 103+22.36, respectively. Given this information: a. Determine the design speed of this curve. (12 points) b. Calculate the distance that must be cleared from the center of the inside lane in order to provide sufficient stopping sight distance (8 points)

A four-lane undivided multilane highway (two lanes in each direction) has 3.4 m lanes and 1.5 m shoulders. At one point along the highway there is a 4% upgrade that is 1 km long. There are 15 access points along this grade. The peak-hour traffic volume has 2500 passenger cars and 200 trucks and buses (no recreational vehicles), and 720 of these vehicles arrive in the most congested 15-min period. This traffic stream is primarily commuters. The measured free-flow speed...

Horizontal Curve Problem- A field measurement of an existing two-lane curved roadway (horizontal curve) indicates that the chord length (C) for the inside radius of the road (roadway edge line) is 312.5 ft and the distance from the middle of the chord to the roadway edge line 25 feet. The road has 28 feet of travel way, 14 feet for each lane. Respond to the next three questions about this horizontal curve. 1. Radius for the horizontal curve to the...

A multilane highway has two northbound lanes. Each lane has a capacity of 1500 vehicles per hour. Currently, northbound traffic is consists of 3100 vehicles with 1 occupant, 600 vehicles with 2 occupants, 400 vehicle with 3 occupants, and 20 buses with 50 occupants each. The highway’s performance function is t = t0 ( 1 + 1.15 (x/c)6.87 ) where t is in minutes, t0 is equal to 15 minutes, and x and c are volumes and capacities in vehicle...

An existing rural 4-lane freeway (2 lanes in each direction) has 11-ft lanes and 2-ft lateral clearance. The freeway hasa peak-hour volume of 1,800 veh/h in one direction, 5% trucks in the traffic stream, and a PHF of 0.92. The freeway has 1 cloverleaf interchange within three miles of the midpoint of segment, and runs through level terrain. No recent field speed data is available. a) Using HCS7, determine the LOS during the peak hour. b) What is the capacity...
