I. Communication and Data Processing Technologies in UAV Traffic Monitoring
(1) Core Application Process
Unmanned Aerial Vehicles (UAVs) employ wireless communication technologies to send image and video data in real-time—these data are automatically collected by the onboard sensors like cameras, radars, and infrared devices (for traffic volume, road conditions, etc.)—to ground control stations or data centers. The ground system is thus processing and analyzing the data further to create practical information, such as traffic condition reports, and records of violations.
(2) Communication Stability Issues: The communication of the UAV depends on wireless communication networks. Even there could be some places or situations where the signal is weak and the coverage is limited, thus the data transmission may be affected by the stability of the connections and that could be the reason for unreliable data transmission.
II. Distributed Control Communication Technology for Highway Tunnel Electromechanical Equipment
(1) Solution Architecture
The intelligence tunnel monitoring based on distributed control technology has been presented the "Area Intelligent Controller (ACU) + Intelligence Distributed Controller (DCU)" paradigm:"
ACU Function: Using standard communication protocols, it gathers monitoring data from DCUs and thus fulfills the requirements of local on-site control.
DCU Function: Through distributed control, it combines IO technology, switch technology, wireless communication technology, and optical fiber ring network communication technology to interact with the scattered electromechanical devices in the tunnel that are connected to the DC.
(2) Application Value
Reorganizes the highway tunnel local control system area structure and functionality and enhances the system interconnection and interoperability of various subsystems.
Decreases the construction difficulty and operation expenses, thus creating a win-win situation for the highway owners, system developers, and integrators, and also demostrates the extensive application potential of distributed control technology in intelligent tunnel monitoring.
III. Key Technologies and Devices for Rail Transit Mobile Communication
(1) R&D and Application of GSM-R Technology
In the '90s, the Ministry of Railways approved the proposal for the digital mobile communication network of Chinese railways based on GSM-R technology, which was the main driver for the digitization of the wireless communication system of Chinese railways. The limitations that were hindering the scaling up of GSM-R projects in China were overcome by solving the key technological problems such as the radio wave propagation and wireless channel models in complex high-speed railway scenarios, GSM-R network interconnection and interoperability, and GSM-R network optimization. Having been completed these tasks laid the foundation for the large-scale construction of GSM-R and served the development of the high-speed railways.
(2) R&D of Core Equipment and Systems
CTCS-3 Wireless Monitoring System: With independent intellectual property rights, it innovates the model of timeout for train control through analysis, locating, and solving. The system, implemented on more than 250 "Fuxing" and "Hexie" EMU trains in 14 railway administrations, lessens the occurrences of the national railway timeouts in train control by 40% and enhances transportation safety.
Heavy-Haul Train Communication Equipment: The complete set of heavy-haul train ground application nodes, and on-board communication units, along with other equipment, has been developed independently. A dynamically changeable networked wireless locomotive synchronous control system has been set up, and the problem of reliable communication in heavy-haul transportation on the Daqin Railway has been solved. The large-scale operation of 20,000-ton heavy-haul trains has been facilitated, thus the annual transportation capacity of the Daqin Railway has been increased from 100 million tons to 450 million tons, making railway heavy-haul transportation a world wonder.

V. Application of V2X Technology in Traffic Signal Control
(1) Technical Principles and Communication Modes
Core Concept: V2X communication is the main enabling technology for Connected Vehicle (CV) technology, which in turn is the main driver of a clean intelligent transportation system (ITS) by unifying the data from vehicles, pedestrians, and infrastructure without the need for additional sensor installations such as geomagnetic detectors.
One or more of the below-mentioned technologies may be used for communication:
cellular communication, Wi-Fi, satellite radio, and Dedicated Short-Range Communication (DSRC).
Main Communication Scenarios:
V2V (Vehicle-to-Vehicle) Communication. After comparisons, the accuracy of GPS devices, the positional stability, the variety of the road and the track, the information on speed and acceleration can be updated.
V2I (Vehicle-to-Infrastructure) Communication: Vehicles send out information like vehicle trajectory, traffic conditions, and signal timing to intelligent systems such as traffic signals, work zones, and toll booths. Con-side, roadside terminals obtain the actual state of local traffic lights and thus, by signaling back the traffic signal control system, the feedback loop is finalized.
