Korean lidar specialist Seoul Robotics has introduced Wrong-Way Detection (WWD) to detect instances of wrong-way driving. WWD employs lidar sensors and a lidar Processing Unit equipped with Seoul’s 3D perception software, SENSR. The system is currently being deployed on US freeways and highways in California, Florida, and Tennessee, as well as in Europe and Asia.

WWD can be used for close or long range proximity based on installation and location requirements. A single lidar sensor can cover a range between 40m to 200m to manage a four-lane off-ramp and filter wrong-way movement as slow as only 3mph. WWD relies on Seoul Robotics’ 3D data which the company says is more granular and accurate than 2D camera data, resulting in fewer false positives compared to conventional or thermal and AI colour camera based systems.

According to Seoul Robotics, a recent test of WWD analysing 100,000 vehicles generated only one false alarm, making the solution 99.9998% effective, compared to alternative 3D detection systems which report up to 70% accuracy. In normal operations on a multi-lane highway ramp, WWD is capable of generating less than one false positive per week, while capturing every wrong-way event, including vehicles slowly backing up to change lanes.

“Smart city technology has the power to save lives, and Seoul Robotics is dedicated to developing the industry’s most advanced smart solutions to improve road safety,” said Jerone Floor, Vice President of Products and Solutions at Seoul Robotics. “Accurate, actionable insights delivered in real-time can make all the difference in high risk situations. ITS solutions like Wrong-Way Detection play a pivotal role in helping governments and authorities keep drivers safe.”

“Seoul Robotics can deliver versatility and accuracy utilising their SENSR software, making Wrong-Way Detection one of the most reliable solutions on the market,” said Bill Corbin, President of MH Corbin. “This technology is critical to creating safer, smarter roadways, and we’re proud to be part of the solution.”

WWD is powered by Seoul Robotics’ proprietary SENSR software which is equipped with deep learning and can detect, track, and classify hundreds of objects simultaneously within 4 centimetre accuracy. The software is specifically engineered to use light-weight algorithms, programmed to filter for wrong-way movement data from 3D sensors, gaining highly accurate insights without significant computing power or cost. Additionally, SENSR features weather-filtering AI capabilities ensuring the highest level of accuracy, day and night, in all conditions, including heavy snow and rain.
