Transportation has always played a key role in the development of cities. But now, as we enter the smart city era, technological infrastructure is more important than ever for ensuring the efficiency of urban travel networks. That's where smart transportation comes in to the picture. It's a solution that simultaneously addresses the needs of traffic management authorities as well as individual traffic participants.
Smart vehicles require smarter roads. The intelligentization of vehicles now makes it possible for traffic participants to exchange and share information in real time and at all hours, regardless of the scenario or weather conditions. Technologies such as AI, 5G, vehicle-to-everything (V2X), and Internet of Things (IoT) are quickly maturing, creating endless possibilities for the construction of smart transportation networks. In smart cities, cameras capture traffic conditions, massive amounts of data are transmitted via 5G between multiple sources at high speeds, and V2X and automated driving offers a new travel paradigm. The result is a comprehensive traffic system that seamlessly coordinates individuals, vehicles, roads, and environments, thereby maximizing the efficiency of urban transportation.
Intelligent perception facilities: Intelligent perception is created with visual perception at its core, and fueled by perception devices such as radars and the compute power of edge AI. It can be used to achieve intelligent recognition and detection, as well as take HD snapshots and perform analysis in real time, which proves useful for tasks such as monitoring speeding on highways and managing electronic toll collection (ETC) lanes. These applications can be applied anywhere, from busy urban intersections to suburban streets, and provides crucial data for traffic operations and planning purposes.
Intelligent connected facilities: These facilities are formed by integrating 5G and V2X with a wide range of data inputs from intelligent perception devices, and then enhancing them with edge computing capabilities. Vehicle-to-infrastructure (V2I) is a technological framework which enables vehicles to fetch data from smart transportation facilities.
- V2I requires road infrastructure to be digitalized and reconstructed. This includes signal lights, radars, cameras, traffic meteorological stations, variable message signs (VMSs), and LED guideboards. By fusing vehicles, roads, networks, and the surrounding environmental data into a single collaborative system, V2I is able to facilitate high-speed, low-latency communication between vehicles and roads via 5G.
- V2X end-to-end low-latency (within 20 ms) direct connection control and HD video backhaul are used to help vehicles obtain dynamic information about surrounding road conditions and traffic participants, so as to prevent traffic accidents from occurring. This makes travel safer and more efficient, while also providing a more effective road management method.
Intelligent guidance facilities: By working in tandem with intelligent perception and intelligent connected facilities, intelligent guidance facilities are able to provide traffic guidance information for drivers and smart vehicles in both visual and V2X modes. This includes signal lights, VMSs, and LED guideboards.
HiSilicon has more than a decade of technical experience in the field of intelligent transportation. Our cutting-edge image capture and processing, AI edge computing, and 5G+V2X, enable us to provide industry-leading intelligent transportation solutions.
Our IPC SoC and NVR SoC series chipsets have been widely used to crack down on traffic violations and manage urban roads. These chipsets feature edge AI compute capabilities and industry-leading 24/7 image capture abilities, which function in all weather conditions.
The chipsets are powered by a CPU+NPU+GPU+IVE+DSP+MCU heterogeneous multi-core processing framework and Linux+LiteOS dual-operating system architecture, and offer powerful AI processing capabilities. They can even run multiple complex tasks at the same time, while remaining ultra-responsive. With their powerful compute capabilities and diverse interfaces, these chipsets make it possible to extract vital information about such complications as complex crossroads, pedestrians, and non-motorized vehicles, and provide the foundation on which cities build efficient transportation systems. In addition, our PON+G.hn chip solution empowers customers to provide transmission capabilities for intelligent perception facilities.
The 5G+V2X Pre-Module solution was released at the beginning of 2020, and is dedicated to helping customers and partners digitalize their roadside infrastructure and boost IoV capabilities. The HiSilicon 5G Pre-Module functions more like a comprehensive 5G module solution than a mere baseband chip, and includes chipsets for baseband processing, RF transceiving, low-noise amplification, and power management. The reference design solution has been verified for commercial use, greatly easing challenges related to module development.
With its embedded V2X function, the 5G Pre-Module can be applied across a wide range of scenarios. It can be installed in road auxiliary devices, including road signal lights and electronic signs, while also supporting the interconnectivity of road sensors and display units, such as cameras, traffic meteorological stations, roadside radars, signal lights, VMSs, raised pavement markers, and digital triangular cones. Thanks to real-time interaction with vehicles and traffic command centers, multiple types of sensory data can be integrated to establish an information digitalization pipeline that provides comprehensive digital road conditions to traffic participants.
