Dynamic Navigation Data Transmission for Wrong-Way Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for warning road users about wrong-way driving often result in delayed or inefficient communication, leading to potential accidents, and face challenges in balancing data efficiency with accurate detection, particularly in high-risk areas.
Innovation Solution
The method involves a client-server system that dynamically adjusts the transmission rate of navigation data based on the vehicle's location, increasing the rate when entering a wrong-way driving area and decreasing it when leaving, to optimize data communication and reduce power consumption, while utilizing additional sensors for enhanced position data accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation data is transmitted continuously at a high rate to ensure accurate wrong-way driver detection, then detection reliability is improved, but data traffic volume and power consumption increase
Solution Approach 1:
The system dynamically adjusts the transmission rate of navigation data based on the vehicle's location. When the vehicle is in a wrong-way risk area, the transmission rate is increased to ensure accurate detection. When outside such areas, the transmission rate is reduced to minimize power consumption and data traffic. This dynamic adaptation resolves the contradiction between maintaining high detection reliability and reducing energy loss.
Solution Approach 2:
The system applies different transmission quality levels to different spatial locations. High transmission rates are applied locally in wrong-way risk areas where accurate detection is critical, while lower transmission rates are used in other areas. This local differentiation allows the system to maintain reliability where needed without unnecessarily increasing power consumption throughout the entire operation.
2Measurement precision
If navigation data transmission rate is increased to improve detection accuracy in high-risk areas, then measurement precision is improved, but data traffic volume increases
Solution Approach 1:
The transmission rate is dynamically adjusted based on the vehicle's location relative to wrong-way risk areas. High transmission rates are applied only when the vehicle is in or approaching a risk area, ensuring high measurement precision when needed. Outside these areas, the transmission rate is reduced, thereby limiting the overall data traffic volume while maintaining detection accuracy when critical.
3Loss of time
If continuous monitoring at high transmission rate is used to prevent delayed detection, then response time is improved, but system productivity decreases due to excessive data processing
Solution Approach 1:
The system dynamically adjusts monitoring intensity based on location. High transmission rates and continuous monitoring are applied only when the vehicle is in or approaching wrong-way risk areas, ensuring minimal detection delay when critical. Outside these areas, monitoring is reduced, improving overall system efficiency by reducing unnecessary data processing while maintaining rapid response capability when needed.

AI summary
The invention relates to a method and system for warning road users of a vehicle (1) that is driving in the wrong direction, said method comprising the following steps: reading (200) navigation data (13) of the vehicle (1) into a server (2) located outside the vehicle via a vehicle-server interface (12) between a communication device (10) associated with the vehicle (1) as a client and the server (2) located outside the vehicle; using at least one piece of server-side navigation information to match (300) the navigation data (13) of the vehicle (1) in the server (2) located outside the vehicle in order to evaluate the read-in navigation data of the vehicle (1) concerning the wrong-way driving of the vehicle (1); if wrong-way driving has actually been determined in the matching (300) step on the basis of the navigation data of the vehicle (1), providing (400) a wrong-way driving warning (14) concerning the wrong-way driving of the vehicle (1) to at least one additional vehicle-server interface (15) between at least one communication device (16), associated with an additional vehicle (3), and the server (2) located outside the vehicle; wherein the matching (300) step includes an analysis as to whether the vehicle (1) is located in a wrong-way driving danger zone (60) of the road network, and, if this is the case, the server (2) located outside the vehicle instructs (310) the communication device (10) of the vehicle (1), according to which instruction the communication device (10) transmits the navigation data (13) at a higher transmission rate than outside the wrong-way driving danger zone (60) in order to initiate a higher-frequency data transmission.
