Roadway curve advisory speed determination
First Claim
1. An advisory speed meter for determining the maximum lateral horizontal acceleration in a vehicle comprising:
- an accelerometer unit capable of sensing the lateral horizontal acceleration experienced in a vehicle, the accelerometer unit mounted on the floor of the vehicle at the vehicle centerline, the front of the accelerometer unit oriented toward the front of the vehicle, the accelerometer unit mounted perpendicular to the vehicle floor, and a meter unit capable of calculating and displaying the maximum lateral horizontal acceleration experienced by the vehicle, the accelerometer unit connected by a connector cable to the meter unit.

Abstract
The advisory speed meter is used to determine the advisory speed for a highway curve or to provide data for use in determining the advisory speed for a highway curve. The meter determines and records the maximum lateral horizontal acceleration experienced by a vehicle and occupants while traversing a highway curve. The meter has been extensively tested on rural curves and on entrance and exit and connecting ramps between all types of highways. The process for determining an advisory speed for a curve is described. The advisory speed meter provides accurate, reproducible data for use in determining advisory speeds for highway curves.
