ROAD MONITORING SYSTEM, ROAD MONITORING DEVICE, AND ROAD MONITORING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18284709 titled 'ROAD MONITORING SYSTEM, ROAD MONITORING DEVICE, AND ROAD MONITORING METHOD

Simplified Explanation

The patent application aims to improve the accuracy of vehicle speed calculation by analyzing an optical signal received from an optical fiber cable laid in a road. Here is a simplified explanation of the abstract:

  • The invention extracts a first pattern based on the vehicle's traveling state in a specific time and distance range.
  • It then generates a second pattern with reduced time points or positions from the first pattern.
  • Finally, it calculates the vehicle's speed on the road using the second pattern.

Potential Applications

This technology could be applied in:

  • Traffic management systems
  • Intelligent transportation systems
  • Vehicle speed monitoring devices

Problems Solved

The technology addresses issues such as:

  • Inaccurate vehicle speed calculations
  • Lack of real-time speed monitoring on roads
  • Difficulty in tracking vehicle speeds in specific areas

Benefits

The benefits of this technology include:

  • Improved accuracy in vehicle speed calculation
  • Enhanced road safety measures
  • Efficient traffic flow management

Potential Commercial Applications

This technology could be commercially applied in:

  • Speed detection devices for law enforcement
  • Automotive industry for speed monitoring systems
  • Smart city infrastructure for traffic management

Possible Prior Art

One possible prior art could be the use of radar technology for vehicle speed detection, which may not provide the same level of accuracy as the optical signal analysis proposed in this patent application.

Unanswered Questions

How does this technology handle adverse weather conditions that may affect the optical signal reception?

The patent application does not specify how the system compensates for adverse weather conditions that could potentially impact the accuracy of the vehicle speed calculation.

What is the cost implication of implementing this technology on a large scale in urban areas?

The patent application does not address the potential costs associated with deploying this technology on a wide scale in urban areas, which could be a significant factor for adoption.


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.
