Traffic pressures are increasing as Guangzhou's urbanization accelerates. Serious congestion, long waiting time, and lack of high-speed information services significantly affect the travel experience. Safety problems are serious, railway transportation and road accidents occur frequently. At the same time, operation efficiency and security monitoring are restricted by the existing network latency, bandwidth, and reliability technologies, and cannot meet the application scenarios of vehicle-road collaboration.
Through 5G technological innovation and in-depth cooperation with the transportation industry, we have built dedicated 5G networks and application systems in multiple fields such as subway, railway, bus, and road-bridge detection, including 5G native trains, 5G train-to-ground communication systems, 5G digital tunnels, 5G high-speed railway early warning systems, 5G under-train detection systems, 5G dispatch buses, etc.
This project has not only benefited the 20 million population in Guangzhou, but also the entire transportation industry and government agencies, including subways, high-speed trains, and public buses, and are now enjoying more efficient operation and management, more automatic scheduling and maintenance, a more user-friendly and safe working environment and higher passenger satisfaction. These provide examples for digital transformation of city governance.
The smart transportation industry is expected to grow dramatically over the next few years. The network atom capability, private network architecture, and cooperation mode in this project can be copied to taxis, train schedules, pulling, airports, ports, and other segmented transportation industries. The smart subway, high-speed rail, bus, and Internet of Vehicles cases in this project have also been widely replicated in other cities in China.

Advanced 5G indoor positioning technology enables passengers to search for points of interest even without GPS
Guangzhou is the third largest metropolitan area in China, with a population of around 20 million.
Guangzhou Metro is the urban rail transit system of Guangzhou. As of first half of 2022, it has a total of 16 lines, reaching621 kilometers, with a daily ridership of 11.5 million. Guangzhou bus services include 1,280 bus lines and the city has a total paved road area of 191 square kilometers.
Given its size, the city is facing multiple challenges to its transportation system. These include ensuring the smooth and efficient operation of trains while limiting incident rates, ensuring the safety and comfort of a large number of passengers, and optimizing resources while reducing costs to create a sustainable transportation system.
Since year 2020, with the advent of 5G, the local transportation industry, together with China Mobile and ZTE, have transformed the traditional transportation system into 5G-enabled smart transportation system. For example, with 5G’s large bandwidth and throughput and ultra-reliability and low latency features the safety and efficiency of the transportation system are further improved. Advanced 5G indoor positioning technology enables passengers to search for points of interest even without GPS.
This large-scale initiative spans the city's entire transportation ecosystem and involves unique deployments of 5G solutions in three major transportation scenarios:
For such a huge metro system with 16 lines and 11.5 million ridership per day, transformation does not come the easy way. Now 5G has been integrated into the overall planning of new subway lines, setting a new standard for subway industry operation.Dedicated 5G receiving antennas and TAUs are innovatively designed for the latest subway trains，all new train leaves the factory with 5G capability.
Enhanced operation efficiency and safety. The total 5G solution was created for operation efficiency and safety. Especially, it changes the operation and monitoring system from traditional passive mode to more active and online mode. For example, the metro train on-time rate has been greatly increased. Also metro operation environment is quite challenging. For example, cracks of the tracks, the track offset may cause severe accident to the trains. Unfavorable waterlogging and fire and unauthorized intrusion may lead to severe adverse situations. Thus, the implemented 5G real-time metro monitoring solution helps to significantly reduce the rate of incidence and cost of maintenance.
Better station operations and management. In the metro stations, mobile electronic guidance screens, intelligent customer service machines, turnstiles , intelligent security control are gradually 5G enabled. These measures help shorten the average processing time for each passenger by 20% during peak hours. 5G enabled HD video cameras in the stations and back-office AI analysis is used for passenger flow analysis, abnormal behavior analysis, and people evacuation. The high-precision 5G indoor positioning can be accurate up to 2 meters, providing passengers with in-station navigation and other position-related services.
Gigabit internet experience on-the-go. Passengers also enjoy wireless gigabit Internet anytime and anywhere in the station hall, platform, and other metro locations. Even in a metro train moving at the speed of 160 km per hour, the download speed can be up to 600Mbps.
Railway, especially high-speed train, has become a symbol of China’s modern transportation system. Guangzhou is home to 10 high speed railway stations. With millions of train passengers per day, safety and efficiency and passenger services are of highest priorities of Guangzhou railway system.
5G early warning system. Due to the high speed of the train, which can be as fast as 100 m/s, even a tiny object on the track may lead to disaster. Thus, for safety, at least 8km in front of the moving train must be monitored with 5G enabled system. If there is any potential intrusion onto the tracks, the back-end system will be analyzed and send a warning message through 5G to the train.
5G train operation data auto backup. For train operations, there are large amount of operation data to be sent back from trains to central back-end system. But currently it relies on tedious manual copying of the data. With the 5G-enabled system, the transmission efficiency is improved by more than 10 times.
5G train suspension inspection system. With 5G, traditional manual train suspension inspection is replaced by 5G-enabled remote inspection system. What would have required two hours of manual inspection back then, takes just two minutes of camera-assisted and AI-driven inspection now.
5G smart railway marshaling station. With a dedicated 5G private network for railway marshaling and production, the integrated automated system reduces the number of front-line production staff from 215 to 150 and the average daily train processing capacity increases from 8,000 to 10,000.
Rich train passenger online services. For the high-speed train passengers, the boring long-distance traveling experience is transformed into an enjoyable one, thanks to rich online videos, audios, eBooks and online courses provided by Tencent.
Guangzhou has 1,280 bus lines and bus route length of 23,000 kilometers, serving the city’s 20 million population. The city also has a total paved road area of 191 square kilometres.
5G Smart Bus
This enables bus control center to monitor bus operations in real time and have a full view of the buses from different angles.
