What will be the changes in our travel methods in the future? How can digital technology and "dual carbon" technological achievements make public transportation smarter and more environmentally friendly? At the recently held 2023 World Transportation Conference, a large number of black technologies related to future transportation development have made a concentrated appearance.

'Ground bound Flight' will fill the gap between high-speed rail and civil aviation

High speed maglev train is a new transportation system with high speed, safety, green and intelligence. As a "small plane" that flies close to the ground, it will fill the gap between high-speed trains with speeds of 350 kilometers per hour and civil aviation with speeds of nearly a thousand kilometers per hour.

Ding Sansan, Deputy Chief Engineer of CRRC Qingdao Sifang Co., Ltd., said during the conference that, based on the actual travel time, the high-speed maglev train is the fastest transportation mode within the 1500 km range, which is suitable for medium and long distance travel as well as commuting in urban agglomeration.

On July 20, 2021, the world's first 600km/h high-speed maglev transportation system, which was developed by CRRC and has full independent intellectual property rights, was successfully launched in Qingdao, marking that China has mastered the complete technology and engineering capability of high-speed maglev.

In contrast, floating tunnels in water are more sci-fi.

Wu Zhiwen, associate professor of the School of Civil Engineering and Architecture of Guangxi University, introduced at the meeting that there are many deep sea fjord channels with wide waters in the world, and it is difficult to achieve connectivity by using long-span bridges and deep tunnels. Therefore, the idea of floating tunnels was proposed.

Unlike general underwater tunnels, suspended tunnels are tubular tunnels suspended in water through their own gravity, buoyancy, and anchoring forces. Its advantage is that it is not limited by span and water depth, and can be built in places with long spans, deep water levels, and steep slopes.

However, the plan currently faces multiple challenges. Weng Mengyong, Chairman of the China Highway Society, stated that the floating tunnel is the forefront direction of future underwater tunnel construction, and hopes that relevant technologies can mature and be implemented as soon as possible.

Digital technology will bring significant changes to the transportation industry

At this conference, experts attending the conference generally believed that the integration of the digital economy and the real economy has become the main line of building a strong transportation country.

At present, China has built the world's largest transportation infrastructure network, ranking first in various indicators such as high-speed rail and highway mileage, bridge scale, and port throughput. However, there is still significant room for improvement in management efficiency, service experience, and other aspects.

Taking traffic accidents as an example, it currently takes at least ten minutes from discovery, reporting to disposal, which not only exacerbates congestion but also makes it easy for secondary accidents to occur.

In response, Tang Daosheng, Senior Executive Vice President of Tencent Group and CEO of Tencent Cloud and Smart Industry, stated that a "full link intelligent" system should be built from perception, computing, decision-making, and control. Creating real-time twins can predict the traffic situation that will occur in the next moment based on current trends, help management departments make real-time decisions, and improve processing efficiency.

Hu Ang, a foreign academician of the Japanese Academy of Engineering and a special professor of the University of Tokyo, took Japan's "Tokio Maruyu" as an example to introduce that the digital twin cities created in this area are completely corresponding to the real environment, the real city changes will be fed back to the digital twin in real time, and digital space can also simulate and deduce the real city accordingly, forming an efficient cycle of online and offline urban design and management.

In addition, multiple digital intelligent technologies were unveiled at the conference. The prefabricated intelligent construction technology brought by China Railway Siyuan Survey and Design Group Group Co., Ltd. can build subway stations like building blocks; The complete set of industrialized intelligent construction technology and equipment for steel bar components constructed by China Communications Second Navigation Engineering Bureau Co., Ltd. has been successfully applied in the project, changing the traditional construction mode of tower column steel bars, achieving the maximum replacement of manual labor with machines, improving the quality and efficiency of bridge construction, and reducing construction costs and safety risks.

Liu Wenjie, Secretary General of the Organizing Committee of this conference and Vice Chairman and Secretary General of the China Highway Society, stated that the combination of digital and transportation will bring important changes and improvements to the application scenarios and service levels of the transportation industry.

Promoting the integration of transportation and energy development to achieve the "dual carbon" goal

Low carbon "is one of the keywords of this conference.

Urban rail transit is a "major energy consumer". At the meeting, the urban transportation energy intelligent management system exhibited by China Railway Siyuan Survey and Design Group Group Co., Ltd. can establish a comprehensive energy measurement system, monitor, diagnose, optimize and intelligently supply energy for urban rail transit, and is expected to reduce 174 tons of carbon emissions per kilometer in the future.

Promoting the realization of the "dual carbon" goal through the deep integration of transportation and energy development has become a consensus among the attending delegates.

Gan Yong, an academician of the CAE Member, believes that China's energy structure will continue to optimize and adjust, and the key point of promoting green and low-carbon transformation of transportation lies in the low-carbon substitution of power and the improvement of energy efficiency of transportation tools.

Yang Zhongsheng, Chairman of China Communications Second Highway Survey, Design and Research Institute Co., Ltd., believes that in the construction of highway infrastructure, achieving the "dual carbon" goal cannot be limited to simply stacking low-carbon technologies or materials, but should be considered from a comprehensive perspective throughout the entire construction cycle, requiring coordination in various aspects such as material production, survey and design, construction, operation and maintenance, disposal and recycling.

Song Ling, chairman of China Energy Construction Gezhouba Group, said that the company will take promoting the integrated development of transportation and energy as the breakthrough and entry point to promote the green and low-carbon transformation of transportation, use the land resources and space resources of Shandong Zaozhou Hezhou Expressway, implement the global new Energy development, and promote energy conservation, emission reduction and carbon reduction. The company will continue to explore the deep integration of energy management and smart transportation, deeply tap into the value of road resources, and promote technological innovation, business model innovation, and market-oriented and large-scale development.
