Question

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 the major road that adequate sight distances are provided. Grades are approximately level.
