Abstract: A client terminal displays, on a display device, a visual feature of each of a plurality of vehicles passing through an intersection at a location where an incident occurred and map data indicating a passing direction of each of a plurality of vehicles passing through the intersection and sends, in response to a designation of any one of the plurality of vehicles, an instruction to set the designated vehicle as a tracking target vehicle to the server. When the instruction is received, a server specifies a camera of the intersection at which the tracking target vehicle is highly likely to enter next based on at least a current time and a passing direction of the tracking target vehicle at the intersection and sends camera information of the specified camera to the client terminal. When the camera information is received, the client terminal displays, on the display device, a position of a camera corresponding to the camera information to be superimposed on the map data identifiably.

Abstract: A vehicle detection system includes a server connected to be able to communicate with a camera installed at an intersection and a client terminal connected to be able to communicate with the server. The client terminal sends, in response to input of information including date and time and a location at which an incident occurred and a feature of a vehicle which caused the incident, an information acquisition request relating to a vehicle which passes through the intersection at the location at the date and time to the server. The server extracts vehicle information and a passing direction of the vehicle passing through the intersection at the location in association with each other based on a captured image of the camera of the camera installed at the intersection at the location at the date and time in response to a reception of the information acquisition request and sends an extraction result to the client terminal.
