Project Overview

       The Institute of Transportation has been tasked to co-formulate the "Plan for Promoting the Efficiency and Safety of Smart Transportation Services" (By Letter of Yuan-Tai-Ke-Hui-Zi No. 1090098342 of the Executive Yuan on September 3, 2020) in accordance with the "Digital Nation Innovative Economic Development Plan," "Taiwan 5G Action Plan," and other major policy implementation focuses. The plan runs from 2021 to August 2025.Construction of 5G intelligent transportation digital nerve center planning and implementation and other plan series. In continuation of the overall planning and idea development in 2021, this plan uses 5G in conjunction with AIoT and other innovative technologies to complete an integrated analysis of the highway transportation network through collection, integration, and massive computing. People and traffic flow, public transportation, traffic signal status, and other real-time statuses were monitored across multiple platforms. In addition, the communication protocol and control of existing transportation control systems, as well as how to connect seamlessly with international mainstream vehicle-to-everything (V2X) protocol standards, were discussed in light of the 5G communication environment and diverse intelligent transportation application requirements and challenges. In addition, during the pre-planning period of 2021, the verification and implementation concepts for intelligent signal control systems for police and fire protection and disaster prevention and rescue vehicles at demonstration sites were planned. This ensures that emergency vehicles have priority for safe passage at intersections, thereby advancing urban smart mobility's core technologies and innovative application services.

Research Results

1. At the digital nerve center implementation demonstration sites of intelligent transportation, equipment deployment operations have been completed. The development of a library of reproducibility and non-reproducibility traffic congestion probability prediction models and a knowledge base related to public transportation management were developed. In addition, the intelligent transportation digital nerve prototype system has been developed through the collection and analysis of real-time transportation information from the demonstration site, as well as the use of digital twin technology.
2. Verification and implementation of the intelligent signal control systems for emergency rescue vehicles have been concluded (verification and implementation of the Shuinan Economic and Trade Park in Taichung City).
3. The second phase of the review of the Urban Traffic Control Protocol Version 3.0 in response to 5G V2X and A.I. requirements (including Changeable Message Sign (CMS), automatic vehicle recognition (eTag and AVI), and "signal control messages" that operate with the Light Rail Transit priority signals) has been completed.

Result Promotion and Benefits

• The "Urban Traffic Control Protocol Version 3.0 Review Results" Exchange Seminar was held on November 8, 2022. People from all sides were invited to discuss the results of the review of the new and existing issues of Urban Traffic Control Protocol Version 3.0, in the hopes that the protocol can keep up with the times. Under the spirit of forward compatibility, future urban smart mobility can support a variety of innovative application services.
• The “Construction of 5G intelligent transportation digital nerve center (2/2) - System prototype development and verification implementation” Result exchange, Symposium, and Technical Seminar was held on November 10, 2022. Director-general and deputy director-general of the Transportation Bureau in six special municipalities, as well as various transportation management and practical application units in Taiwan, shared and discussed the implementation results at the seminar. The plan's major research results and application experience were then promoted.
• Two articles of relevant research planning results were published in "The 2022 International Conference and Annual Meeting of the Chinese Institute of Transportation" to facilitate comprehension, discussion, and application by people from all sides.
