In other words, the control of the signal lights at a certain road intersection, such as the green light passing time, is a fixed time value, or only considers the traffic conditions at this road intersection for control, and does not consider the road traffic at the intersection adjacent to the road intersection situation

Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0032] Usually, a junction may be connected with many roads, but any junction on urban roads often has two main roads, and at most there are only two main roads. When congestion occurs at each traffic intersection of urban roads, since the traffic flow on the main road is usually the largest, it is often the two most congested roads, and their traffic pressure is the greatest; Alleviating or avoiding congestion is more conducive to alleviating the congestion of t...

The invention discloses an intelligent traffic control method for traffic signal lamps of the smart city. The method comprises that the congestion indexes of roads of crossings are obtained periodically, and the congestion indexes of trunk roads are stored in a trunk road crossing state table; if the congestion index of any road is greater than the first threshold, the trunk road crossing state table is inquired to obtain identification of the main trunks as well as allowance identifications of upstream and downstream crossings; if signal lamp linked control is allowed in crossings adjacent to the main trunk on the basis of the allowance identifications of upstream and downstream crossings, the trunk road crossing state table is inquired to obtain a first congestion index and first green light passing time corresponding to the identification of the main trunk, a second congestion index and second green light passing time of the adjacent upstream crossing, and a third congestion index and third green light passing time of the adjacent downstream crossing; and the green light passing time in the main trunk direction is controlled in a linked manner based on the congestion indexes and the green light passing time. The method of the invention can be used to guide vehicles in the main trunk road rapidly and avoid traffic jam from becoming serious.
Description
technical field [0001] The invention relates to the field of intelligent traffic signal control in a smart city, in particular to a method capable of intelligently controlling traffic signal lights at a traffic intersection according to traffic conditions at the intersection. Background technique [0002] Since the 1980s, China's urbanization process has continued to advance. In large cities such as Beijing, Shanghai, Guangzhou, Shenzhen, and even some small and medium-sized cities, the number of motor vehicles has increased rapidly, and urban road congestion has become increasingly serious. In order to ensure the normal operation of vehicles between urban roads, traffic lights must be set at each road intersection to control the passing vehicles. The traffic signal control at the intersection is mainly realized by the traffic signal controller. Therefore, traffic signal controllers play an increasingly important role in daily life. [0003] Usually, the control of the tra...
