Question
The deflection angle between two tangents is 95 degrees. Calculate the minimum radius (meters) that would be acceptable for a curve connecting these two tangents, assuming a Design Speed of 110km/hr and corresponding fmax of 0.12. Note: Your answer should be provided to ONE decimal place.

Transcribed Image Text:Following on from Question 1 and 2, and assuming the design superelevation was 6.5%, calculate
the maximum speed (km/hr) that a design vehicle could safely traverse the 620m design radius. You
should assume that gravity is 9.81 m/s. Note: Your answer should be provided to ONE decimal place.

Transcribed Image Text:Following on from Question 1, and to enable a more conservative design to the minimum radius,
620m has been chosen as the design radius. Calculate the design superelevation (%). Note: Your
answer should be rounded UP to the nearest whole 0.5% (e.g. if 5.2% then round up to 5.5% and if
5.7% then round up to 6%) .
