The invention provides a traffic signal cycle time calculating method and a traffic signal cycle time calculating device. The traffic signal cycle time calculating method comprises the following steps: calculating the traffic intensity of each phase according to the flow and time occupancy ratio, which are detected by a sensing detector, of each phase of a road intersection; calculating the sum of the traffic intensities of all phases of the road intersection; and calculating the traffic signal cycle time of the road intersection according to the traffic intensity of the road intersection. Inthe invention, the traffic signal cycle time of the road intersection is calculated according to the time occupancy ratio and flow information of the road intersection, which means the acquisition ofthe traffic signal cycle time takes both the influences of the flow information of the road intersection and the influences of the time occupancy ratio of the road intersection into consideration; therefore, a high-density and low-flow traffic state can be reflected effectively, the traffic signal cycle time of the road intersection can be calculated accurately according to the time occupancy ratio and flow information, and the reliability of the traffic signal cycle time calculating method is improved.
Description
technical field [0001] The invention relates to the technical field of traffic control, in particular to a method and device for calculating the cycle duration of traffic signals. Background technique [0002] At present, with the improvement of people's living standards, cars are widely used in people's daily life. Simultaneously, the quantity of automobile is also increasing day by day, and traffic pressure is increasing, especially the traffic pressure at road intersection place is bigger. Therefore, it is necessary to calculate the cycle time at the intersection according to the actual traffic conditions. The cycle time is the sum of the green light time in all directions, so that the green light time can be determined by the cycle time, so that the cars at the intersection can pass smoothly. [0003] In the prior art, there are various methods for calculating cycle duration, for example: TRRL method, ARRB method, HCM method and conflict point method. The cycle duratio...
