Technology for upgrading and renovating the transportation infrastructure is a full range of technologies that look forward to improving the facilities by bringing in such advanced technologies as information technology, material technology, management methods, and many others into the existing highway, bridge, tunnel, port, and airport infrastructures. Technology is meant to raise the security, efficiency, eco-friendliness, and "smartness" of these infrastructures. The following conversation features detailed core technology systems, typical applications, engineering practice cases, and future trends analyses:
1. Intelligent Transportation Systems (ITS)
Vehicle-Road Collaboration Technology: A 5G-V2X communication network is used by the technology to achieve real-time data transfer between vehicles and road infrastructure (like traffic lights and roadside sensors) thus supporting such functionalities as instant route planning and blind-spot alert. For example, in highway pilot projects, cars can get data in advance about accidents or heavy traffic areas and, hence, they can automatically adjust their driving methods.
Adaptive Signal Control: The intelligent traffic light system that uses a reinforcement learning algorithm can change the green light duration dynamically depending on traffic flow density, thus, it also reduces the vehicle waiting time by 15%-20% and the fuel consumption by more than 10%.
Traffic Big Data Platform: The platform gets data from cameras, millimeter-wave radars, lidar, etc., and forecasts traffic flow by employing deep learning models to the resources be used in the most efficient way. For instance, through the evaluation of historical data alone, a city was able to enhance the traffic efficiency of its main roads by 25%.
2. Green and Low-Carbon Technology
Integration of Renewable Energy: It is the distributed photovoltaic power stations on the roofs of the service areas, slopes, and central dividers, together with flexible DC power supply systems that accomplish energy self-sufficiency for highways. As an illustration, a mountain highway is able to provide 60% of the electricity demand of its service areas through a "photovoltaic + energy storage" system.
Resource Utilization of Solid Waste:
Steel Slag Asphalt Mixture: After going through the carbonation process, industrial steel slag fully takes over the part of the crushed stone for road surfaces, which, on the one hand, leads to a reduction of project costs by 10%-15% and, on the other hand, contributes to the decrease of carbon emissions.
Fluidized Fly Ash Backfilling: It uses fluid materials that are made by mixing fly ash and cement to fix the problem of vehicle bouncing at bridge approaches, thus, it achieves a low-carbon solid waste utilization goal.
Warm-Mix Asphalt Technology: It changes road construction temperature of an asphalt mixture by 30-50℃ through mechanical foaming, therefore the reduction of energy consumption and the release of harmful gases is achieved. This technology is suitable for road repair projects.
3. Non-Destructive Testing Technology
Ground-Penetrating Radar: This device is utilized for locating pavement voids and subgrade defects with an accuracy of several centimeters.
UAV Inspection: Utilizing high-definition cameras and infrared sensors, it can rapidly acquire large-scale facility status data and is great for mountain highways and long tunnels.
4. Intelligent Driving Supporting Facilities
High-Precision Mapping and Positioning: By delivering centimeter-level accurate data about roads, lane lines, and roadside facilities, it allows autonomous vehicles to plan their route and make decisions. For example, an autonomous driving demonstration zone achieved L4-level vehicles' driving without maps by fusing lidar point cloud data with high-precision maps.
Intelligent Charging Network: The ultra-fast charging piles (power ≥ 200kW) are the ones that are located in highway service areas and busy city areas, thus electric vehicles can be given an 80-kilometer range extension in merely ten minutes. In addition, it facilitates the power grid and vehicles to interact in a bidirectional way through V2G (Vehicle-to-Grid) technology.
1. Highway Upgrading
Intelligent Service Areas: Operate the area with an environmentally friendly solar energy supply, lead the users to the free parking spaces by means of intelligent parking, and accomplish the "zero-carbon service areas" by the ultra-fast charging of new energy vehicles.
Smart Tunnels: Energy-Saving Lighting: It places the prefabricated integrated lighting units and the brightness is changed automatically depending on the light of the surrounding area detected by the dedicated sensors, thus, the energy consumption is lessened by 30%.
Safety Management and Control: By means of digital twin technology, it becomes possible to monitor real-time traffic flow in the tunnel. If there is an accident, it rapidly initiates the emergency lighting, ventilation, and lane indicator changes.
2. Urban Transportation Hub Renovation
Comprehensive Transportation Centers: Through the use of BIM (Building Information Modeling) technology, the various transportation means such as subways, buses, and taxis are integrated to optimize the transfer paths. As an instance, the Phase III expansion project of Guangzhou Baiyun Airport shortened the design cycle by 20% through BIM models and also realized construction progress dynamic tracking.
Intelligent Parking Systems: The implementation of video recognition together with geomagnetic sensors provides parking space reservation and reverse car search as services, the parking lot utilization rate being raised to more than 85%.
IV. Development Trends and Challenges (Note: The original text skips "III. Engineering Practice Cases" and directly uses "IV"; the numbering is retained for consistency with the original structure)
1. Deepening Technology Integration
Vehicle-Road-Cloud Integration: It combines the information obtained from vehicles, roads, and the cloud thus resulting in the worldwide optimization of autonomous driving decisions. One pilot project, for example, was able to reduce the congestion time on highway sections by 18% through the cloud servers coordinating the collaborative lane changing of multiple vehicles.
Combination of Digital Twins and AI: It uses generative AI for the creation of traffic operation scenarios under severe weather conditions, and it comes with the emergency plans in advance.
2. Greenization and Sustainability
Zero-Carbon Transportation Infrastructure: The objectives such as the utilization of photovoltaic pavements and the adoption of hydrogen refueling stations for heavy-duty hydrogen trucks are among the promoted technologies in the transportation sector, carbon emissions being planned for a 20% decrease by 2030 as compared to 2020.
Circular Economy Model: The complete lifecycle of waste asphalt and concrete is taken care of by setting up an industrial chain for recycling, regeneration, and utilization which, in turn, leads to the resource recycling rate being more than 70%.
3. Improvement of Policies and Standards
Inter-Departmental Collaboration Mechanism: In order to break down the information silos among different departments, creating a data platform that allows data sharing among the transport, energy, industry, and information technology departments is of utmost importance. A city, for instance, achieved the linked regulation of traffic signals and power grid load through data integration from traffic police, meteorology, and electric power departments.
Safety Assurance System: The system improves network security protection for intelligent transportation systems, and security is also provided through the use of blockchain technology that ensures data immutability, while regulations on the determination of liability in the case of autonomous driving accidents are established.
The technology for the renovation and upgrading of the transportation infrastructure is the primary factor that can bring about the promotion of the high-quality development of the transportation industry. Essentially, through technological empowerment, it is targeting the reconstruction of a "safe, efficient, green, and intelligent" transportation system. Hence, it is still necessary to keep up with the pace of technological innovation, work on the policies and regulations, investment models, and at the same time not forget about public participation and data security if there is a desire to fully facilitate the achievement of the strategic goal of the "Transportation Power" building.
