Problems solved by technology
[0004] However, in the prior art, it is difficult to obtain the signal period length of the signal light directly from the signal light manufacturer. Moreover, the phases maintained by the signal light manufacturer and the transit time information corresponding to each phase are not complete and accurate, which may lead to the inability to target the corresponding Formulate a traffic control plan at the intersection; or it may lead to an inaccurate traffic control plan formulated for the corresponding intersection, making the traffic control for the corresponding intersection unable to achieve the expected effect

The invention discloses a trajectory processing method, a trajectory processing device and electronic equipment. The trajectory processing method comprises the following steps: acquiring a selected driving direction of a specified intersection and a conflict driving direction having a conflict relationship with the selected driving direction; acquiring a first trajectory which passes through a specified intersection and is matched with the selected driving direction in a preset statistical time period, and a second trajectory which passes through the specified intersection and is matched withthe conflict driving direction; determining the signal period duration of the specified intersection according to the first trajectory and the second trajectory; and performing traffic control on thespecified intersection according to the signal period duration.
Description
technical field [0001] The present invention relates to the technical field of traffic control, and more specifically, to a trajectory processing method, a trajectory processing device, an electronic device, and a computer-readable medium. Background technique [0002] With the continuous advancement of digital construction, intelligent transportation has been paid more and more attention as a solution to "urban diseases". Among them, intelligent transportation is to use big data, cloud computing, artificial intelligence and other technologies to reshape the relationship between people, vehicles and roads to manage urban traffic. [0003] In the prior art, the signal cycle duration of signal lights is the most basic input information in intelligent transportation. Usually, it is necessary to formulate a traffic control plan for the corresponding intersection according to the signal period length of the signal light, so as to control the traffic at the intersection. [0004...
