Road disaster response support system and program, road management method

There was a lack of understanding of cavity warning signs during normal times, and in the event of a disaster, advance road clearance plans could not be dynamically updated to reflect the actual situation, resulting in delays and personal delays. There was no integrated operation of authority adjustment across multiple administrators, allocation of equipment and personnel, preparation for communication outages, or reflecting knowledge from training and past performance. Solution: The information acquisition department collects data from satellites, optical fiber, vehicles, etc., and the analysis department performs integrated analysis. The road clearance department registers a preliminary plan, and the road clearance implementation plan is dynamically optimized based on the analysis results. The feasibility of achieving 24 / 48 / 72-hour targets is evaluated using reinforcement learning, and consideration is given to determining the transfer of authority, spatial optimization of bases and equipment, redundant communications, heavy equipment operation and robotics collaboration, training and performance learning, and conflict assessment through intellectual property investigations. Multi-hazard risks are quantified and weighted by priority, and a redundant network is formed in conjunction with the evaluation of bases such as roadside stations. Special equipment and sea and air transport are integrated, and abandoned vehicle removal and the automatic assembly of contracted companies are controlled, and emergency restoration plans are automatically generated along with alternative route selection.
