来月から日本の道路が全部こんな感じになるみたいだな
A rumor that "all roads in Japan will look like this starting next month" is causing a huge stir on social media! People are speculating about smart roads that glow and display information, straight out of a sci-fi movie. While many are thrilled, others are skeptical, calling it fake news or wondering about rural areas, leading to a massive online buzz.

Smart Road
A Smart Road is a next-generation road system that integrates IoT technology, AI, and communication technologies into road infrastructure to dramatically improve traffic safety, efficiency, and sustainability. Beyond traditional paving functions, it boasts a wide range of features: embedded sensors monitor road conditions and traffic in real-time, LED panels visually display information, and even wireless power transfer to vehicles beneath the surface is possible. For example, specific smart roads can detect freezing temperatures via sensors and automatically scatter de-icing agents or display warning signs. Furthermore, Vehicle-to-Infrastructure (V2I) technology, where vehicles and road infrastructure communicate directly, provides real-time traffic and accident information to vehicles, enabling optimal route guidance to disperse traffic and contribute to CO2 emission reduction. In Japan, the Ministry of Land, Infrastructure, Transport and Tourism promotes smart infrastructure development as part of "i-Construction," with pilot projects reporting concrete results such as reductions in traffic casualties and improvements in logistics efficiency. If this technology were introduced to all roads in Japan, it would fundamentally transform conventional road traffic.
Level 5 Autonomous Driving
Level 5 autonomous driving refers to the most advanced "full automation" within the SAE International (formerly Society of Automotive Engineers) 6-level classification of autonomous driving (Levels 0-5). Vehicles at this level assume all driving tasks under any driving conditions or environments, completely eliminating the need for human intervention. This means that even controls like steering wheels or pedals are unnecessary; occupants simply input a destination to travel. While current automakers primarily aim for Levels 3-4, Level 5 faces not only technical challenges but also multifaceted issues such as legal frameworks, social acceptance, and cybersecurity. However, if all roads in Japan were to become "like this" with smart road integration, the significantly increased information provision from the road infrastructure would reduce the burden on vehicle-side autonomous driving systems, making Level 5 autonomous driving a more realistic prospect. For instance, high-precision sensors embedded in the road could detect vehicle positions to the millimeter, and transmit real-time traffic light and construction information to vehicles, enabling safer and smoother operation. This is expected to dramatically reduce traffic accidents, shorten travel times, and even provide mobility solutions for the transportation-disadvantaged.
Digital Twin
A Digital Twin refers to a virtual replica, or "twin," of a physical object or process (in this case, "Japanese roads") recreated in cyberspace. By leveraging real-time sensor data and various other information, the conditions of the physical space are reflected in the digital model, allowing for simulations and analyses within it. In the field of road infrastructure, building a digital twin of the real road network enables centralized management and analysis of traffic volume, road surface conditions, weather information, and even surrounding building and environmental data. For example, traffic simulations can predict congestion if construction occurs in a specific section, or verify the effectiveness of introducing a new traffic control system in advance. This allows for optimal infrastructure management and urban planning to be formulated without affecting actual roads. If all roads in Japan become "like this," it implies a future where this Digital Twin technology forms the foundation, with real roads and digital road spaces constantly synchronized and providing mutual feedback. This will enable advanced infrastructure operations such as early detection of anomalies, development of efficient maintenance plans, and rapid recovery support during disasters. This will be an indispensable technology for creating safer and more comfortable travel experiences.
