Three-legged intersection has 4 crossing conflicts (A) True (B) False

Q-A cross-over occur between two Meter Gauge parallel tracks of same crossing number 1 in 12 with straight intermediate portion between the reverse curves and the distance between the centers of tracks is 3.5 m. If the value of G is 1 m, find the intermediate straight distance.

Instructions: Please provide complete solution for full credit and box final answer/s.   Problem: The perpendicular distance between two parallel tangents of a reversed curve isequal to 8m and has a central angle of 8°. If the radius of the first curve is175m., compute the stationing of the PRC if the PC of the first curve is at Sta. 0+120.46.

A recreation park is planned to be constructed consisting of 2 roads tangents to a circular arc which is concave towards the point of intersection of two tangent roads. Each tangent road and the arc of the circle is 1 mile long and are boundaries of the park. Compute the radius of the circular arc?

On a horizontal curve of a two-lane rural highway, the available sight distance is 250m. If the speed limit is 90kph, then is it necessary to mark the section as a passing zone? Also give suggestions to make this section of highway, geometrically economic.

solve it corre

When the bridge is located first, in most cases the resulting highway alignment is the best true or false?

A two lane national highway having design speed of 50 kmph passing through a hilly terrain has a horizontal curve of radius equal to ruling minimum radius. Design all geometrical features of the curve. Calculate set back distance for SSD also.

Two straight parallel roads distant 10.7 m c/c apart are to be connected by a reverse curve of same radius such that maximum distance between tangent point is 41.5 m. What is the allowable radius?
