Applied Information, Inc., the leading provider of intelligent transportation infrastructure technology, announced today that the U.S. Patent and Trademark Office has granted the company a patent covering its Connected Vehicle computing and communications method that significantly reduces the amount of bandwidth needed for traffic signals and other traffic control devices to communicate with vehicles.
U.S. Patent 11,594,127 entitled Systems, Methods, and Devices for Communication Between Traffic Controller Systems and Mobile Transmitters and Receivers describes a system that sends real-time, connected vehicle messages from a traffic signal or other traffic control over the C-V2X Network (Uu) or C-V2X Direct (PC5). The technology enables a reduction of bandwidth usage by up to 97 percent.
“This patent represents a significant advance in the very foundation of connected vehicle communications,” said Bryan Mulligan, President of Applied Information, Inc. “As more and more devices and other vehicles start communicating with each other on the roadway, eliminating unnecessary and repetitive communication will make the system of connected vehicles more efficient.”
Conventional traffic signals and other control devices send messages 10 times per second, repeating the same message until a change in status. Traffic control devices equipped with Applied Information’s technology send messages to nearby connected vehicles only as necessary and when there is a change of status – such as a traffic signal changing from red to green, thereby significantly reducing the amount of data.
