Highly accurate system for wrong-way driving detection and deterrence

摘要

The present invention is a highly accurate detector system for detecting and responding to wrong-way driving incidents. An optimum configuration and combination of sensors gather data corresponding to predetermined vehicle movement test parameters; a set number of parameter deviations from pre-determined thresholds will initiate various sensor signals. The sensor signals may be transmitted to the computer processor, which may in turn produce a range of system outputs. In various embodiments, system outputs may include but are not limited to outputs activating other system components, outputs initiating data storage and analysis, and outputs interfacing and communicating with other systems.

1. A detector system for detecting and deterring wrong-way driving events, comprised of:
at least one first vehicle motion sensor configured to measure at least one first predetermined vehicle movement test parameter and to transmit a first sensor signal to said at least one computer processor when said at least one vehicle movement test parameter corresponds to a first threshold; at least one additional vehicle motion sensor configured to measure at least one additional predetermined vehicle movement test parameter and to transmit at least one additional sensor signal to said at least one computer processor when said at least one additional predetermined vehicle movement test parameter corresponds to an additional threshold; and at least one visual sensor device which is configured to collect visual data and transmit a visual data output to said at least one computer processor, wherein said at least one computer processor is configured to receive and process said first sensor signal and said additional sensor signal to invoke functions to produce system outputs to activate at least one traffic control device and to interface with at least one external communications system, wherein said system is configured with a combination of said vehicle motion sensors and said at least one visual sensor device to achieve a target rate of error Es that approaches 0 as the number of sensors increases wherein Es is a function of a rate of error of each individual sensor within said system, expressed by the following formula:Es=E1+…+Enn2 where n represents a total number of sensors in said system and Ei is an error rate for a given vehicle motion sensor or visual sensor device, where i=1 . . . n.
