Method for presenting result of determination of whether vehicle is stopped, device for determining whether vehicle is stopped, and system for determining whether vehicle is stopped

A vehicle-stop determination apparatus that determines from GPS information of a vehicle whether the vehicle has stopped, the apparatus comprising:

• a low-velocity-section extracting section that extracts a low velocity section being a section from a position of the vehicle at a first time point at which a measured velocity falls below a predetermined value to a position of the vehicle at a second time point at which the measured velocity exceeds a predetermined value, the measured velocity being a velocity of the vehicle obtained from the GPS information;
• a vehicle-velocity-transition-model generating section that generates a vehicle velocity transition model indicating temporal transition of a velocity which decreases from the first time point and subsequently increases continuously to the second time point, using, as constraint conditions, a section distance which is a length of the extracted low velocity section and a time from the first time point to the second time point;
• and
• a stop determination section that determines that the vehicle has stopped in the low velocity section, on condition that there is a section in which the velocity is zero or lower, in the generated vehicle velocity transition model.

A vehicle-stop determination system that determines from GPS information of a vehicle whether the vehicle has stopped, the vehicle-stop determination system comprising:

• a terminal apparatus installed in the vehicle;
• and
• a server apparatus that processes information concerning a traveling status of the vehicle,
• wherein
• the terminal apparatus includes:
• a GPS receiving section that receives a GPS signal, and acquires GPS information of the vehicle from the received GPS signal, and
• a traveling data transmitting section that transmits to the server apparatus traveling data including the acquired GPS information and identification information of the vehicle, and
• the server apparatus includes:
• a traveling data receiving section that receives the traveling data transmitted from the terminal apparatus,
• a low-velocity-section extracting section that extracts a low velocity section being a section from a position of the vehicle at a first time point at which a measured velocity falls below a predetermined value to a position of the vehicle at a second time point at which the measured velocity exceeds a predetermined value, the measured velocity being obtained by measuring a velocity of the vehicle from the received traveling data,
• a vehicle-velocity-transition-model generating section that generates a vehicle velocity transition model indicating temporal transition of a velocity which decreases from the first time point and subsequently increases continuously to the second time point, using, as constraint conditions, a section distance which is a length of the extracted low velocity section and a time from the first time point to the second time point,
• a stop determination section that determines that the vehicle has stopped in the low velocity section, on condition that there is a section in which the velocity is zero or lower in the generated vehicle velocity transition model, and
• a determination result output section that outputs a determination result determined by the stop determination section.
