Huawei's ORT Technology Removes Highway Toll Gates

[Shenzhen, China, July 24, 2019] Huawei recently announced that its ORT technology will effectively facilitate the removal of expressway toll gates at provincial borders, thus greatly reducing traffic congestion and transportation costs, and making road transport more convenient.

The major reform is a milestone for the entire transportation industry, driving digital transformation and evolution towards smart highways. Facing a tight schedule and significant workload, the removal project needs to overcome five technical challenges.

Challenge One: Implementing Management and Control to Prevent Toll Losses

Huawei leverages cloud computing, big data, IoT, and AI technologies to provide double assurance for the management and control of toll evasion and losses.

Level-1 assurance: Huawei's intelligent license plate recognition cameras support online algorithm upgrade to continuously improve recognition accuracy, and the cameras feature Huawei-proprietary chips with high computing power. As new license plate recognition algorithms are developed and loaded, the cameras achieve a higher recognition rate with better accuracy, maximizing return on investment (ROI). The cameras support the software-defined feature. They can automatically identify all weather conditions, including heavy rain, snow, and fog, and adjust imaging parameters accordingly to ensure clear snapshots of each license plate and vehicle. Huawei's intelligent license plate recognition cameras with global shutter technology are designed specifically for highways. This technology enables a license plate recognition rate of over 99% when vehicles are driving at a speed of 220 km/h.

Level-2 assurance: Based on Huawei's digital platform capabilities, build a real-time, accurate toll collection and inspection big data cloud platform featuring cloud-edge synergy between the provincial center and electronic toll collection (ETC) gantries. Use edge computing on the ETC gantry system to implement real-time analysis and matching between recognized license plates and vehicle information detected by road side units (RSUs). Report exceptions to the provincial center and synchronize the information to relevant toll gates for timely management and control.

Challenge Two: Ensuring the Stability, Reliability, and Security of New ETC Gantry Systems

In terms of stability and reliability, make sure that toll collection services can run properly for a long time without suffering core data losses, including toll collection data and license plate images.

Over two million Huawei FusionCube cabinets have been deployed worldwide by 310+ carriers, governments, and enterprises. The cabinets withstand myriad hostile environments, such as those with temperatures below –40°C and over +50℃, and can operate 24/7 without disruption. The nodes of the integrated smart site perform intelligent edge computing, carrying toll collection and billing services. The nodes are deployed in redundancy mode and support hot standby to enable seamless service switchover and ensure toll collection continuity upon a single point of failure (SPOF). The site uses SSD all-flash disk arrays to bear and store core data. The arrays are equipped with redundant controllers to prevent SPOF, and use redundant array of independent disks (RAID) technology to quickly restore data in the case of a disk fault. It takes less than 30 minutes to restore a TB of data.

Huawei leverages its technical advantages in network and security domains and uses proprietary chips to safeguard security. Security protection measures, such as IP address filtering and network access authentication, prevent hackers from accessing or hindering the toll collection system. Collaboration between network and security is implemented to block attack sources when necessary. Huawei-proprietary chips are deployed in sensing, computing, storage, and communications devices of Huawei ETC gantry systems, toll gates, road section centers, and the provincial center, ensuring chip-level security and controllability of the entire system.

Challenge Three: Achieving Unified O&M Management

Huawei provides an integrated operations management platform for numerous ETC gantry systems. The platform intelligently manages key functional modules, such as FusionCube cabinets at integrated smart sites of ETC gantries, power supply systems, power backup systems, cyber security modules, edge computing modules, and data storage modules on a unified GIS map. This helps comprehensively operate and manage open road tolling (ORT).

Challenge Four: Tight Schedule and Challenging Tasks, Requiring Quick and High-Quality Project Construction

Measure twice, cut once. The seemingly simple ETC gantry system needs to be designed and verified in advance in that it involves multiple procedures, including engineering commissioning and functional module collaboration. The Huawei ETC gantry system adopts an integrated design to prevent heterogeneity, interoperability, and compatibility issues between software and hardware modules. In particular, the collaboration between heterogeneous systems from various brands and suppliers is avoided, greatly reducing integrated commissioning costs at the construction site. Huawei's integrated smart sites have undergone pre-testing and verification at Huawei's Suzhou OpenLab and Beijing R&D center. In addition, the sites have been tested on highways in multiple cities, to confirm that the sites meet technical specifications and requirements of the ETC gantry system.

Device supply, construction mode, and resource support need to be fully prepared as well. Huawei has already established one competence center at its HQ, two remote delivery centers, and 31 provincial delivery centers, with 150+ project management experts and 4,000+ delivery engineers. These comprehensive resources support the removal of all expressway toll gates at provincial borders.

Challenge Five: Enabling Smooth Technology and Investment Upgrade to Maximize ROI and Evolve Towards Smart Highways

Huge investment has been put into ETC gantry systems, which are critical infrastructure for future operating services of toll roads. Applying cutting-edge technologies to facilitate smooth upgrade to smart highways and maximize ROI is paramount.

Huawei's integrated smart site of ETC gantry supports collaboration and scalability, and is compatible with multiple technologies, such as 5G. The site contains Huawei-proprietary AI chips and uses intelligent edge computing to enable license plate recognition image deduplication, secondary recognition of images, vehicle model recognition, and HD video analysis, promoting more accurate toll collection and inspection. Simultaneously, the site provides technical support for 5G technology and V2X on smart highways, maximizing hardware ROI.

Huawei is a leading global information and communications technology (ICT) solutions provider and is committed to innovating in the transportation industry. We work with partners to build an open, cooperative industry ecosystem and promote digital transformation of the transportation industry to create a better connected world.
