a) A stopping sight distance of 180m is available for placement of a warning sign of an impending hazard ahead on a road designed for 100km/hr The road is situated outside a rural town in the Westem Cape and is surfaced with asphalt ata longitudinal slope of -2.5% toward the hazard. Accidents are being regularly reported on this section of road in the winter months. If a brake and perception time of 1.7 seconds is assumed, use the table below and evaluate the SSD condition. Motivate all the assumptions made in your calculations. Reference Geometric Design Extract Notes (3) b) A section of road has an entry grade of-8,43% and an exit grade of -4,96%. Determine the minimum vertical curve length (use K,LA) and the stopping sight distance for worst case scenario. The design speed of the road is 80km/hr. Attach or type all workings. Marks allocated accordingly. Reference Geometric Design Extract Notes.
