With reference to Chapter 3.4 of Cycling by Design, the design speed for cyclists on a local access link is 30 km/h.

According to DMRB CD109, 100km/h is a suitable design speed for a new rural road.

A highway is to be designed with 120km/h design speed. At

one section, an equal tangent vertical curve must be designed to connect grades

of +2.0% and –2.0%. Determine the length of curve required assuming provisions

are to be made for minimum stopping sight distance, where the driver’s eye

height =1.25m and the object height =0.5m).

A horizontal curve on a two-lane highway is designed with a 1020m

radius, 3.65m lanes and a 120km/h design speed. 

Determine the distance that must be cleared from the inside edge of the

inside lane to provide sufficient sight distance for minimum safe stopping

distance of 215m.

Calculate the maximum crossfall on a road with a horizontal

curve of 500 metres and a design speed of 85 km/h.  Assume the coefficient of side friction is 0.15.

Convention:

Superelevation – positive slope

Adverse camber – negative slope

Calculate the maximum safe speed (km/h) on a road with a

horizontal curve of 350 metres. The superelevation on the curve is 5% and the

coefficient of side friction is 0.18.

In a cycle stopping experiment, the

initial speed of a bicycle is 30km/h on a level pavement.  The coefficient of friction of the cycle path

surface is 0.2.  Calculate the actual

braking distance.
