For a highway with design speed of 100 kmph, the safe overtaking sight distance is (assume acceleration as 0.53 m/s2)
The speed of overtaking and overtaken vehicles on a highway are 85kmph and 70kmph respectively. Calculate the overtaking sight-distance needed for two way traffic. Assume the acceleration of the overtaking vehicle as 2.5kmph per second and the speed of the vehicle in the opposite direction as 85kmph
On one way traffic road, the speeds of overtaking and overtaken vehicles are 80 kmph and 50 kmph respectively. If the acceleration of the overtaking vehicle is 2.5 kmph per second, calculate the overtaking sight distance (Assume spacing between vehicles is 16 m, reaction time of driver is 2 seconds)
An ascending gradient of 1 in 45 meets a descending gradient of 1 in 60. A summit curve has to be designed gradient for design speed of 80 km/h so as to provide a safe overtaking sight distance of 230 m. Estimate the length of the summit curve.
If the design speed is 80 kmph, perception reaction time 3 seconds and coefficient of friction is 0.5, the safe stopping sight distance is
