LIDAR TAKES THE WAIT OUT OF TOLL QUEUES
A combination of LiDAR sensing and machine learning creates novel vehicle classification based faster tolling system
A
new technology partnership is set to transform road tolling for both providers and motorists alike by using the latest advances in lidar technology and data analytics.
Lidar technology developer Cepton in California
has collaborated with machine learning experts at MechaSpin in Florida to develop a system that produces detailed 3D classifications of vehicles in real time for automated tolling applications. The system combines Cepton’s Sora-P60 with MechaSpin’s MSx software to enable immediate profiling and classification of vehicles at motorway speeds in a wide range of weather and lighting conditions. Traditional tolling systems generally depend on
physical infrastructure to reduce vehicle speed and use a combination of tollbooths for manual processing and fast-track lanes for subscription payment models. Manual tolling can cause congestion and frustration for motorists. More advanced systems allow faster tolling but often depend on inaccurate or unreliable road sensors that can mis-classify or fail, resulting in manual tolling. The Cepton system eliminates the need for physical
infrastructure while providing accurate data – such as vehicle velocity, size and axle count – in a format that can be integrated with other sensor, data capture and billing systems. The result can be automated ANPR billing systems, the hardware for which is designed for aerial installation and contains minimal moving parts, reducing the likelihood of failure.
48 /// Testing & Test Houses /// February 2020 The LiDAR sensor is based on Cepton’s micro
motion technology (MMT). Unlike traditional beam-steering technologies – such as spinning LiDAR and micro-electronical mechanical systems (MEMS) –MMT architecture enables a mirrorless, frictionless and rotation-free system to improve durability, reliability and manufacturability while delivering high-range and high-resolution for highly accurate 3D sensing. According to Neil Huntingdon of Cepton, the
combination of the MechaSpin technology and machine learning software enables the unique and powerful capabilities of LiDAR to be fully exploited. “We believe that this partnership will bring major
innovations to the tolling industry. Our Sora-P60 lidar delivers an unrivalled scan speed at 380Hz, making it possible to profile vehicles as they pass at motorway speeds. Our partnership with MechaSpin will allow for faster, more accurate and lower cost management of our transport infrastructure as the number of vehicles continues to grow globally.” According to MechaSpin’s Danny Kent, the tolling
industry currently lacks an integrated end-to-end system for deploying 3D LiDAR for vehicle classification and tracking. “MechaSpin and Cepton have partnered to deliver
a system to fill this gap,” he said. “Cepton’s LiDAR technology coupled with MechaSpin’s MSx processing engine offers a robust system for tolling, intermodal and other transport industry applications.” T&TH
