The figures below present two scenarios of an intersection layout with vehicle 'A' on the minor road and vehicle 'B' on the major road with a building (shaded) at one corner of the intersection. Vehicle 'A' in its quest to cross the intersection must look for an appropriate gap based on the intersection sight distance to be able to cross safely without colliding with vehicle 'B'. i. Compare the intersection sight distance provision of the two scenarios ii. What accounted for the results in (i) above? AN(3) AN(5) How would you improve the intersection sight distance irrespective of iii. the scenario? AN(2) Line af sight Scenario 1 Scenario 2 Note: The drawinas are of the same scale Note: The drawings are of the same scale b) The 'e' value of a crest curve is found to be greater than the eye height of the driver above the road surface. Determine the minimum length of the curve, if a hazard is assumed to be at the level of the carriageway.
