    摘要: An information processing method includes a step of acquiring movement information on a first mobile body including information on a first position through which the first mobile body is scheduled to pass in a first time slot and information on a travel direction of the first mobile body and a step of setting, as an exclusive area in the first time slot, an area between the first position and a second position on a travel direction side of the first mobile body from the first position based on the movement information on the first mobile body. The exclusive area is set in a manner that the second mobile body other than the first mobile body is not permitted to move within the exclusive area in the travel direction different from the travel direction of the first mobile body in the first time slot, and the second mobile body is permitted to move within the exclusive area in the same travel direction as the first mobile body in the first time slot.

    摘要: A state estimation method executed by a state estimation apparatus including a processor and a memory storing program instructions that cause the processor to estimate a state related to congestion on a subject lane, includes acquiring a state related to congestion of a monitoring vehicle traveling on a non-subject lane, counting a number of vehicles traveling on the subject lane, the vehicles being overtaken by the monitoring vehicle or being oncoming vehicles passed by the monitoring vehicle, and estimating the state related to the congestion on the subject lane, using the state related to the congestion of the monitoring vehicle and the number of vehicles. In the estimating, when the number of the vehicles is equal to or greater than a threshold value according to the state related to the congestion of the monitoring vehicle, the state related to the congestion on the subject lane is estimated as traffic congestion.

    摘要: A vehicle control method is provided such that when a host vehicle is stopped at a front of a vehicle line of vehicles in accordance with a stop signal of a traffic light at an intersection, the engine is stopped by using an idle stop control. When either a left-turn or a right-turn will be made after the traffic light changes to a go signal, a presence or an absence of a traveling body, which is stopped on a side of or behind the host vehicle in a direction from which the host vehicle is turning, is detected during the stop signal. Upon determining the traveling body is stopped on the side of host vehicle, restarting of the engine is placed on standby even when the traffic light turns to the go signal, and the engine is restarted in accordance with a behavior of the traveling body.

    摘要: The present application discloses a traffic monitoring device capable of switching camera modes, comprising a sensor group, a infrared camera group, a visible light camera group, a visible light camera head, a infrared camera head, a head driver and a digital signal processor. The sensor group comprises pressure sensor, photoelectric displacement sensor and photosensitive sensor; the infrared camera and the visible light camera collect image information. The above devices are used as the detection front ends connected to the digital signal processor. The head driver adjusts the angle of the visible light camera and the infrared camera in real time. The system described in this application has two working modes: continuous shooting and interval shooting, which shortens the working time of the system, extends the life of the system, and reduces the cost of the system. The shooting camera can be switched according to the light intensity, to avoid the dazzling effect of supplementary visible light on human eyes, and to reduce hidden dangers to traffic safety. The camera angle can be fine-tuned with no dead angle shooting. License plate recognition and illegal shooting can be performed at all weather.
