What does a positive gradient represent?
Visualize if you're climbing uphill.
The deviation angle is calculated as what?
Think about how two slopes can meet.
Vehicle A operates at a stable speed on a +6% gradient, while Vehicle B operates on a -3% gradient. Calculate the deviation angle when the two vehicles meet at a junction.
Remember to consider the signs of both gradients.
You are tasked to design a road where two gradients intersect, one at +4% and another at -2%. How would you convey this in a design plan?
Think about what makes logical sense for vehicle speed and safety.
