Software-Defined Lidar Solution for Automated Tolling
Perception sensors define the reliability and performance of automated tolling systems. However, current technologies, such as cameras, radars, and loops have significant limitations. Cameras and radars often struggle to detect vehicles reliably in low light or adverse weather conditions and misclassify 2-axle vs. 4-axle vehicles. They are unable to provide highly accurate depth information, lack the resolution needed to accurately classify objects at range, and have difficulty tracking vehicles when last-second lane changes occur prior to entering a tolling area. To put it simply: cameras, radars, and loops are unable to meet today’s challenge of optimizing traffic flow while ensuring people and goods move safely.
