All lanes are 12 ft wide. If a stop sign is installed on the minor road, determine the dimensions ofallrequired clear sight triangles at this intersection for passenger cars(Case B, stop sign control on the minor road).In basic intersection design principles, which of the following statements are always true:I. Intersections with grade separation are better than intersections at-grade.II. Signalized intersections are better than unsignalized intersections. a. I b. II c. All of the above d. None of the above
- Q3c. At a three leg (T) intersection, the two-way peak hour volume on the minor road is 500 veh/hr and that on the major road is 600 veh/hr. As a Traffic Engineer, what type of intersection control will you propose? What is the basis of your proposal?A signaled intersection can improve the traffic density of a certain road segment. Choices: A. True B. FalseWhat should be the design minimum acceleration lane length for a flat parallel-type entrance ramp/curve terminal with a design speed of 45mph connecting to a highway with a design speed of 70 mph at a grade separated interchange?
