16. Calculate the safe Stopping Sight Distance on a level road stretch for design speed of 120 km per hour if the road is a one lane two way road. Assume coefficient of longitudinal friction as 0.35 and reaction time of driver is 2.5 s. 17. Calculate the minimum sight distance to avoid head on collision of two cars approaching from the opposite directions at 90 km per hour and 60 km per hour speeds. Assume reaction time of the drivers are 2.5 s and coefficient of longitudinal friction as 0.35. 18. Calculate the minimum sight distance to avoid head on collision of two cars approaching from the opposite directions at 90 km per hour and 60 km per hour speeds. Assume reaction time of the drivers are 2.5 s and coefficient of longitudinal friction as 0.7 with a brake efficiency of 50 percent. 19. Calculate the minimum sight distance to avoid head on collision of two cars approaching from the opposite directions at 120 km per hour speeds. Assume reaction time of the drivers are 2.5 s and coefficient of longitudinal friction as 0.50 with a brake efficiency of 75%. 20. Calculate the Stopping Sight Distance on a highway with descending gradient of 2% and maximum speed permitted is 80 km per hour. Assume other data suitably. 21. Calculate the Stopping Sight Distance on a highway with ascending gradient of 2.5% and maximum speed permitted is 90 km per hour. Assume other data suitably.
