Mobility Information System for Emergency Vehicle Path Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic driving systems face challenges in accurately sensing and avoiding other mobile bodies, particularly in unpredictable situations such as sudden movements or blind spots, leading to potential collisions and hindrances during emergency vehicle operations or road disasters.
Innovation Solution
A mobility information provision system that collects and processes field information from multiple communication apparatuses to generate course-related information, allowing vehicles to safely navigate by determining and controlling their movement to avoid collisions and prioritize emergency vehicle paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle uses its own sensor to capture images and avoid contact with other mobile bodies, then collision avoidance is improved, but the ability to detect unpredictable movements and blind spots deteriorates
Solution Approach 1:
The patent combines multiple communication apparatuses located at different positions (roadside, other vehicles, infrastructure) to create a unified information collection network. This merging allows the system to overcome the limitations of individual vehicle sensors by aggregating data from multiple sources, thereby improving detection accuracy for unpredictable movements and blind spots while maintaining collision avoidance capabilities
Solution Approach 2:
The server acts as an intermediary that collects field information from multiple communication apparatuses, processes this information to generate course-related information, and distributes it to vehicles. This intermediary approach enables vehicles to access information beyond their own sensor capabilities, improving detection of mobile bodies in blind spots and unpredictable situations without requiring each vehicle to have advanced sensing equipment
2Reliability
If course-related information is generated for all mobile bodies to prevent collisions, then safety is improved, but hindrance to emergency vehicle movement increases
Solution Approach 1:
The patent applies different quality levels of course-related information to different mobile bodies based on their characteristics and urgency. Emergency vehicles receive prioritized information that ensures their path remains clear, while other vehicles receive standard collision avoidance information. This local differentiation allows the system to maintain high safety standards for all vehicles while ensuring emergency vehicles can move without hindrance
Solution Approach 2:
The server generates course-related information in advance that considers the potential movement patterns of emergency vehicles. By preemptively planning courses that avoid areas where emergency vehicles may need to travel, the system prevents hindrance before it occurs. This preliminary action allows normal traffic to be routed in ways that do not block emergency pathways, maintaining both safety and emergency response efficiency

AI summary
A mobility information provision system includes a collector, a mapping unit, a generator, and a controller. The collector collects information about movement of mobile bodies. The mapping unit maps positions of the mobile bodies on the basis of the information collected by the collector. The generator generates course-related information by using information including the positions of the mobile bodies mapped by the mapping unit. The controller controls movement of each of the mobile bodies, by using the generated course-related information, or information obtained on the basis of the course-related information and usable for determination or control of the movement of the corresponding one of the mobile bodies. The generator generates the course-related information for each of the mobile bodies, to prevent hindrance to movement of a first mobile body moving in emergency, out of the mobile bodies.
