Method of estimating intersection control

摘要

A method of estimating the type of intersection control for two or more roadways includes steps of classifying each roadway at an intersection and estimating the type of intersection control used for each roadway. Roadways can be classified by size, traveling speed, number of lanes as well as any other roadway characteristics. In some cases, a warning system can be operated using the estimated intersection control type for each roadway.

1. A method of controlling a motor vehicle with a control system, the method comprising:
monitoring, with the control system, the motor vehicle at or near an intersection of a first roadway and a second roadway; determining, by the control system, whether traffic control information associated with the intersection is stored in a database available to the control system; wherein, upon a determination by the control system that traffic control information is not available for the intersection, the control system estimating a type of intersection control device associated with the intersection by performing a steps of: retrieving a first characteristic of the first roadway; retrieving a second characteristic of the second roadway; associating the first roadway with a first class using the first characteristic to select the first class from a plurality of classes according to a roadway classification scheme; associating the second roadway with a second class using the second characteristic to select the second class from the plurality of classes; comparing the first class and the second class; and determining the type of intersection control device based on the comparison of the first class and the second class, the intersection control device being associated with the first roadway; wherein the step of determining the type of intersection control device for the first roadway is followed by a step of determining a type of intersection control device for the second roadway.
