What is the difference between continuous curves and reverse curves?

[ReidFitz]

Continuous curves and reverse curves have the following specific differences: 1. Location aspect: Traffic warning signs for reverse curves should be placed at appropriate positions before two adjacent curves with opposite directions. Traffic warning signs for continuous curves should be placed at suitable positions before roads with more than three consecutive curves. 2. Outcome aspect: Continuous curves are extremely dangerous. If driven improperly at excessive speeds, they may lead to severe consequences such as accidents and fatalities. Traffic warning signs on reverse curves are designed to alert drivers to reduce speed, with a safe driving speed not exceeding 60km/h. Most traffic warning signs for reverse curves are found on mountainous roads.
