A four-leg intersection with no traffic control is formed by two two-lane roads with the speed limits on the minor and major roads being 30 and 40 mi/h, respectively. If the roads cross at 90° and a building is to be located at a distance of 48 ft from the centerline of the nearest lane on the minor road, determine the minimum distance (in ft) at which the building should be located from the centerline of the outside lane of...

3-25 Calculate the minimum passing sight distance required for a two-lane rural roadway that has a posted speed limit of 45 mi/h. The local traffic engineer conducted a speed study of the subject road and found the following: average speed of the passing vehicle was 47 mi/h with an average acceleration of 1.43 mi/h/sec, and the average speed of impeder vehicles was 40 mi/h.

1. Find the stopping sight distance (in feet) for traveling downhill at a grade of 3% and speed of 60 mph, assuming driver’s perception and reaction time of 2.5 sec and a deceleration rate of 9.3 ft/s2. 2. A temporary diversion has been constructed on a highway of +3% grade due to major repairs that are being undertaken on a bridge. The maximum speed allowed on the diversion is 25 mi/h. Determine the minimum distance from the diversion that a...

A horizontal curve on a two-lane highway (12 ft lanes) has a PC at station 123+80 and PT as station 129+60. The central angle is 30 degree, the super-elevationis 0.06 and 22 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum sate speed (assuming current design standards) to the nearest 5 mi/h.

Question 1 What are objectives of intersection design? A two-lane minor road with + 1% approach grade in the North-South direction intersects a two- lane major road in the East-West direction that has a speed limit of 60mph, a +4% approach grade torming a four-leg intersection. A building is located in the South-east corner of the intersection such that the distance from the centerline of the nearest lane on the minor road to the building is 50 major road is...

Problem 4. A section of a two-lane highway has 12-ft lanes and a design speed of 75 mi/h. The section contains a vertical curve and a horizontal curve. The vertical curve connects a-2.5% grade and a +1.5% grade. The PVT of this vertical curve is at station 36 + 50. The PC of the horizontal curve is located 294 ft before the PVC of the vertical curve. The horizontal curve has superelevation of 8% and central angle of 38 degrees....
