20140172295 | METHOD AND APPARATUS FOR CAPTURING ROAD CURVE PROPERTIES AND CALCULATING MAXIMUM SAFE ADVISORY SPEED - This invention relates generally to the field of Highway signage and more specifically to a device for automatically capturing road curve properties and a process for automating calculating the maximum safe Advisory Speed of Roads. This invention is a new device that automates the accurate measurement of road curve/Railway radius and super elevation. This information is assembled to automatically report the recommended curve speed, or Curve Advisor Speed (CAS) for a particular curve. The device is assembled into a single, compact, low power and transportable case which can be driven at normal road speeds in a car. | 06-19-2014 |
