TRAFFIC FLOW MONITORING DEVICE, TRAFFIC FLOW MONITORING METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18286888 titled 'TRAFFIC FLOW MONITORING DEVICE, TRAFFIC FLOW MONITORING METHOD, AND RECORDING MEDIUM
The traffic flow monitoring device described in the patent application includes a detection unit that compares a first reference speed with the average speed of a vehicle at a prescribed spot on the road at a specific time. An approximate speed calculation unit then calculates an approximate speed based on the change in average speed at or before the specific time. A determination unit analyzes the change in traffic flow at the prescribed spot by comparing the approximate speed with a second reference speed.
- Detection unit compares first reference speed with average speed at prescribed spot and time
- Approximate speed calculation unit derives approximate speed based on change in average speed
- Determination unit analyzes traffic flow change based on comparison results
Potential Applications: - Traffic management systems - Road safety monitoring - Transportation planning and optimization

Original Abstract Submitted
The traffic flow monitoring device includes a detection unit that outputs a first comparison result, which is a result of comparing a first reference speed and an average speed at a first time, on the basis of speed data associating a time with an average speed of a vehicle travelling through a prescribed spot on a road, an approximate speed calculation unit that derives an approximate speed at the first time on the basis of a change in the average speed at or before the first time and a determination unit that determines a change in the traffic flow at the prescribed spot on the basis of the first comparison result and a second comparison result which is the result of comparing the approximate speed and a second reference speed.
