Step by step
Solved in 2 steps
- Determine the total stopping distance (m) for a road with speed limit of 53kph and grade of 4.4%.Determine the total stopping distance (ft) for a road with speed limit of 79mph and grade of -2.5%A four-lane undivided highway (two lanes in each direction) has (3.4m) lanes, with (1.2 m) shoulders on the right side. There are 4.5 access points per km, and the posted speed limit is 80 km/h. What is the estimated free-flow speed?
- If 420’ are available as Sight distance on an urban highway having a 2.5% grade. Assuming all the parameters according to ASHTO, find maximum speed which can be posted on the highway for safe travelling.A two-lane minor road intersects a two-lane undivided major road at 90 degrees, forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 50 m from the center line of the outside lane of the major road and 14 m from the center line of the nearest lane of the minor road. A passenger car on the minor road would like to cross the major road. Using the AASHTO procedure, determine the maximum speed that can be allowed on the minor road if the design speed on the major road is 80 km/h. Assume a 3% approach grade for the minor road. Note: 1km/hr = 0.62mi/h, 1ft = 0.3048mwhen desiging an auxiliary lane, the deceleration length need to be determined. Briefly explain what is the deceleration length and how to determine it
- A divided multilane highway in a recreational area has four lanes (two lanes in each direction) and is on rolling terrain. The highway has 10-ft lanes with a 6-ft right-side shoulder and a 3-ft left-side shoulder. The posted speed is 50 mi/h. Previously, there were 4 access points per mile, but recent development has increased the number of access points to 12 per mile. Before development, the peak-hour factor was 0.95, and the directional hourly volume was 2200 vehicles with 13% heavy vehicles. After development, the directional hourly volume is 2600 vehicles with the same vehicle percentages and peak-hour factor. What is the LOS before and after the development?Plz, solve this problem. Transportation Engineering-2 A four-lane highway (2 lanes in each direction) with 3.65m lanes has a horizontal curve designed for a 380 m centerline radius, and a 110 km/hr design speed. The grade is level. Use a driver perception reaction time of 2.5 sec and a vehicle deceleration rate of 3.4 m/sec2. Determine the closest distance any roadside object may be placed to the centerline of the inside lane of the roadway.(note: Do not round any value. Use calculated values).A four-lane urban freeway segment has a peak demand volume of 3,500 vehicles per hour for the two eastbound lanes. The PHF is 0.95 and there are no trucks, buses or RVs because the freeway is classified as a parkway and such vehicles are prohibited. The segment has 12 ft lanes, no lateral obstructions, 3 ramps within the influence area, and meanders through some beautiful rolling terrain. Assuming the road will be used by commuters and those familiar with the road, what is the flow rate (pcphpl)? Provide your answer to the nearest integer.
- A 960 m segment of 5.2 km four-lane undivided multilane highway in a suburban area is at a 1.5% grade. The highway is in level terrain and lane widths are 3.35 m. The measured free flow speed is 73 km/hr. The peak hour volume is 1900 veh/hr, PHF is 0.9 and there are 13% truck and 2% RVs. Determine the LOS, speed, and density for upgrade and downgrade.An existing six-lane divided multilane highway with a field-measure free-flow speed of 45mph serves a peak-hour volume of 4,000 vehicles per hour, with 10% trucks (50% SUT, 50% TT). The PHF is 0.88. The highway has generally rolling terrain. What is the likely level of service for this segment? Good weather, no incidents, no work zones, and regular drivers may be assumed.Determine the superelevation of a road section on an urban area with a design speed of 110kph, and Rmin=630m. What can you say about the computed value of e?
