Device to Reduce Vehicles Entering the Freeway Traveling in the Wrong Direction    

Cost-effective, timely, and realizable means to reduce the possibility of a motor vehicle entering a freeway ramp in the wrong direction of travel

Overview

Motor vehicles entering freeway ramps in the wrong direction of travel have long been a cause of injury or death. Worse, these incidents almost always involve multiple vehicle collisions owing to the domino effect. A statistically insignificant number of these incidents are caused by unanticipated, and often unavoidable, weather conditions such as fog, rain or snow with some accidents being attributed to elderly drivers. However, there is no doubt that the major and predominate cause of vehicle accidents are due too the use of alcohol or drugs. To date there have been numerous patents issued and suggestions submitted in an attempt to resolve the "Wrong Direction" problem by various means. The vast majority of these involve implementation of physical obstacles at freeway ramps that are configured with equipment to detect the direction of vehicle travel and when appropriate activate mechanical obstacles. Alternately attempts to stop vehicles, currently in use by some law enforcement agencies, is to destroy a vehicles electrical system with high intensity electromagnetic pulses (EMP) that, although causing irreparable damage, causes the vehicle to stop. Major obstacles in implementing any of these solutions are: their complexity, construction costs, maintenance, the large number of sites involved, and time. It is therefore unlikely that even a small fraction of these systems will be implemented--at least not in the near future.


The patent technology is a system for reducing the possibly of a vehicle entering a freeway ramp in the wrong direction of travel, towards oncoming traffic. The system is comprised of equipment used in conjunction with orbiting satellite transceivers with receivers, such as Global Positioning Systems (GPS) or a navigation/assistance service, housed in a vehicle and having the ability in real time to compute the receiver's, and consequently the vehicle's, longitude, latitude, and direction of travel. These devices in collaboration with a controller and freeway-mounted mirrors constitute a timely, cost-effective, realizable, and simple means to reduce the possibility of entering a freeway ramp in the wrong direction of travel.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 701: Data Processing:Vehicles, Navigation, And Relative Location

This class provides for electrical computers, digital data processing systems, and data processing processes for transferring data between computers or processes wherein the computers or processes employ the data before or after transferring and the employing affects the transfer of data therebetween. This class is for electricalapparatus and corresponding methods for performing data processing operations in which there is a significant change in the data or for performing calculation operations wherein the electrical data processing system or calculating computer functions to indicate a condition of a vehicle, to regulate the movement of a vehicle, to monitor the operation of a vehicle, or to solve a diagnostic problem with the vehicle. It also provides electrical apparatus and corresponding methods wherein the electrical data processing system or calculating computer function to determine the course, position, or distance traveled. It further provides electrical apparatus and corresponding methods wherein the electrical data processing system or calculating computer functions to determine the relative location of an object (e.g., person or vehicle) and may include communication of the determined relative location to a remote location. In this class there are three main divisions: 1. vehicle control, guidance, operation or indication; 2. navigation; 3. relative location

Subclass 117: Traffic analysis or control of surface vehicle
