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 80 feet. If the intersectio ave to change to: feet and the distance to the building from the centerline of the outside lane of the n has no control and the vehicle on the major road will speed, determine the maximum speed that would allow drivers on the minor road (1) Adjust speed. (2) Stop.

    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...

    please, make your writing readable Intersection Sight Distance A developer has requested permission to build a large retail store at a location adjacent to the intersection of a divided four-lane major road and a two-lane minor road. Traffic on the minor road is controlled by a stop sign. The speed limits are 35mph and 50mph on the minor and major roads, respectively. The building is to be located at a distance of 65ft from the near lane of one of...

    Two automobiles with equal mass approach an intersection.  One vehicle is traveling eastward and the other vehicle is traveling northward.  The vehicles collide and stick together. After impact they travel on the road and then travel on a gravel covered shoulder until both cars stop. Only the northward bound vehicle left skid marks at an angle of 55 degrees north of east.  A police officer posted at the intersection clocked the eastward vehicle at 29 mph before impact. The northward...
