Abstract

[Challenges] Traditionally, road infrastructure maintenance has focused primarily on emergency response after accidents, making it difficult to manage the risk of road hollowing during normal times. Furthermore, there have been challenges in the dynamic use of pre-planning and real-time decision-making support during road clearing in the event of a disaster. Moreover, with the increase in foreign visitors to Japan, the need for multilingual road disaster response information is growing, and there is a demand for flexible support technologies that can integrate preventive maintenance, disaster response, and multilingual support. [Solution] This invention relates to road maintenance and disaster response technology, and provides a support system that uses sensing means such as artificial satellites, optical fibers, and vehicle movement to predict infrastructure hollowing risks during normal times and to formulate road clearing implementation plans based on pre-registered road clearing plans during disasters. Furthermore, it is equipped with a multilingual information provision function, enabling effective support for foreign visitors to Japan and others. [Selection Diagram] Figure 1

Description

The present invention relates to technologies for road maintenance and road clearing during disasters, and more particularly to a road disaster response support system, related programs, and road management methods that, based on information acquired using multiple sensing means (such as satellite sensing, optical fiber sensing, and vehicle movement sensing), perform risk assessments and soundness assessments of road infrastructure during normal times, and in the event of a disaster, rapidly formulate road clearing implementation plans to ensure the passage of emergency vehicles, etc., by utilizing pre-formulated road clearing plans. Furthermore, the aim is to provide a flexible and advanced support system that functions effectively in both normal and disaster phases, by achieving both wide-area and continuous infrastructure monitoring, which was previously difficult, and rapid decision-making and planning support in the initial stages of a disaster. This system contributes to building a road management system with high disaster resilience by seamlessly supporting both the preventive maintenance phase and the disaster response phase. Traditional road infrastructure management systems typically focus on emergency response after incidents such as road collapses or subsidence occur, and there is a lack of a well-established system for comprehensively and continuously monitoring road hollowing risks and signs of deterioration during normal times. Furthermore, in the event of a disaster, rapid road clearing is required to ensure the passage of emergency vehicles such as ambulances, firefighters, and the Self-Defense Forces, but the information acquisition and decision-making processes necessary for formulating implementation plans are often dependent on individual expertise, and there is a lack of efficient and scientific support technologies. In recent years, advancements in sensing technologies such as artificial satellites, optical fibers, and connected cars have made wide-area road monitoring technically possible. However, there have been limited implementation examples of integrating these technologies for both infrastructure health assessment and disaster road clearing planning. Furthermore, survey methods such as ground-penetrating radar are point-based and intermittent, making continuous and area-based assessment impossible. Consequently, there have been limitations in detecting early signs of disaster risk and making immediate route decisions immediately after a disaster. On the other hand, in the event of a large-scale disaster, it is considered a crucial administrative task to implement "emergency recovery (road clearing)" prior to normal recovery procedures to ensure access to medical facilities, evacuation centers, and disaster relief bases. Road clearing, in this context, refers to the process of removing obstacles and making simple repairs immediately after a disaster to enable the passage of emergency vehicles as quickly as possible. To achieve this, a system is needed to accurately compare pre-formulated road clearing plans with actual information at the time of the disaster and quickly translate this into a road clearing implementation plan. However, conventional technologies lack the functionality to dynamically utilize road clearing plans. For example, they do not adequately implement processes such as updating plans to reflect damage conditions and traffic disruption information after a disaster, or optimizing the timing of implementation. Furthermore, the use of AI (artificial intelligence) technology to flexibly process information interpretation, weighting, and route optimization is insufficient, leading to increased decision-making burdens on the ground and delays in initial response. Furthermore, with the recent increase in inbound tourism, the risk of foreign tourists visiting Japan facing natural disasters such as earthquakes, typhoons, heavy rains, and volcanic eruptions has also increased. However, when a disaster strikes, foreign travelers have limited means to quickly and accurately obtain information on passability and evacuation routes. Language barriers and differences in information acquisition channels have led to delays and confusion in responses. Therefore, there is a need to develop a system that provides easy-to-understand and timely disaster-related transportation information to a diverse range of users, including inbound tourists.
