ROAD MONITORING SYSTEM, ROAD MONITORING DEVICE, AND ROAD MONITORING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240161609 titled 'ROAD MONITORING SYSTEM, ROAD MONITORING DEVICE, AND ROAD MONITORING METHOD
Simplified Explanation
The present disclosure involves a method to improve the accuracy of vehicle speed calculation using an optical signal received from an optical fiber cable laid in a road. The method includes extracting a first pattern based on the traveling state of a vehicle in a specific time and distance range, generating a second pattern with reduced time points or positions based on the first pattern, and calculating the vehicle's speed using the second pattern.
- Extract first pattern based on vehicle's traveling state in specific time and distance range
- Generate second pattern with reduced time points or positions from the first pattern
- Calculate vehicle speed using the second pattern
Potential Applications
This technology can be applied in:
- Traffic management systems
- Intelligent transportation systems
- Vehicle speed monitoring and enforcement
Problems Solved
- Inaccurate vehicle speed calculation
- Lack of real-time speed monitoring on roads
Benefits
- Improved accuracy in vehicle speed calculation
- Enhanced traffic management and safety
- Real-time monitoring of vehicle speeds
Potential Commercial Applications
Optical speed calculation technology can be utilized in:
- Traffic control and management companies
- Law enforcement agencies for speed enforcement
- Automotive industry for vehicle speed monitoring systems
Possible Prior Art
One possible prior art is the use of radar technology for vehicle speed detection, which may not provide the same level of accuracy as optical speed calculation.
Unanswered Questions

The article does not address how the system compensates for weather conditions that could impact the accuracy of speed calculation.
What is the cost comparison between optical speed calculation and traditional radar-based systems?
The article does not provide information on the cost implications of implementing this technology compared to existing radar systems.
Original Abstract Submitted
to improve the accuracy of vehicle speed calculation, the present disclosure extracts, on the basis of an optical signal received from an optical fiber cable laid in a road, a first pattern according to the traveling state of a vehicle on the road in a first time range and a first distance range, generates, on the basis of the first pattern, a second pattern in which the number of time points included in the first time range or the number of positions included in the first distance range has been decreased, and calculates the traveling speed of the vehicle on the road on the basis of the second pattern.
