Determine the minimum length of a vertical curve in a residential street if the grades are –4% and +3%. A design speed of 10 km/h higher than the posted speed limit has been adopted for this road. Consider the most common and desirable assumptions for road design in Australia. Assume stopping sight distance for this road is higher than the length of the vertical curve. Consider passenger car to obtain the height of eye of driver and object height (car tail light). Select one: a. None b. 35 c. 64 d. 81
