Guangzhou, China, November 11, 2019] Guangdong Expressway Group recently announced that it will work with Huawei to build a backbone transmission network that covers Guangdong Province's expressway system. This is one of the largest infrastructure construction projects to fully realize free-flow tolling since China announced it would cancel all inter-provincial toll booths on expressways. This project will leverage Huawei's OptiXtrans Network solution to provide ultra-broadband and stable networks for future smart transportation services on expressways, such as real-time vehicle identification, electronic toll collection (ETC), and vehicle-road cooperation. It protects the transmission of critical production data on expressways and allows drivers to travel more safely and conveniently.
"Huawei is committed to building ubiquitous optical connectivity and making cutting-edge optical communications technologies benefit all industries," said Kim Jin, President of Huawei Enterprise Transmission & Access Domain. "We are delighted to cooperate with Guangdong Expressway Group to promote the implementation of free-flow expressway tolling in full and support the smooth evolution of future smart transportation services, such as autonomous driving. Through continuous technological innovation, we will improve the quality of transportation and logistics services as well as people's travel experience, and better promote economic integration and development in the Pearl River Delta region."
Currently, there is a large number of inter-provincial toll booths deployed on the expressway system across Guangdong Province, which leads to traffic congestion, especially during peak hours or holidays. The gradual cancellation of inter-provincial toll booths is a revolutionary change to expressway tolling. In the future, the ETC system will be used massively on expressways to enable the free flow of vehicles, improve transportation and logistics efficiency, and enhance cost effectiveness.
Guangdong Expressway Group's plans to install a large number of ETC sites in Guangdong center on constructing a network that can transmit massive volumes of data between data centers and the ETC gantry system, including real-time charging and billing information of unattended sites. In addition, this network needs to implement unified bearing and isolation of various services on expressways to improve security. Against this backdrop, Huawei has proposed the OptiXtrans Network solution to build dedicated optical transmission channels for Guangdong Expressway Group. This solution has the following key values:
- 100G OTN, building a smooth and high-speed information channel
Huawei-developed 7 nm chips provide industry-leading 100G/wavelength performance and support ultra-low microsecond-level latency, ensuring vehicle-road cooperation.
- Industry-grade security assurance, safeguarding production data transmission on expressways
Physical isolation and optical-layer encryption guarantee data security. In addition, automatically switched optical network (ASON) protects services against multiple fiber cuts to achieve 99.999% availability that is required by the transportation industry.
- Unified bearing of various services, improving network O&M efficiency
WDM hard pipes carry high-priority services, such as charging and voice services, while Ethernet soft pipes carry office, video surveillance, and bandwidth sharing services, improving bandwidth utilization.
