A pavement signal lamp control method between adjacent intersections based on a particle swarm algorithm is disclosed. The control method comprises the following steps that 1) division is performed through referencing time periods of historical traffic data; the time periods divided according to traffic flow changes in the historical traffic data are collected, the time periods with the small flow changes are divided together, and a traffic flow peak period and a smooth period are distinguished; 2) a pavement signal lamp phase is set; 3) traffic data of a pavement and a motorway is collected in real time, and a signal phase state and phase time are calculated; 4) whether a current green light phase demanding degree of the pavement and the motorway satisfies a signal lamp phase conversion condition is determined; 5) when the current green light phase demanding degree satisfies the signal lamp phase conversion condition, the signal lamp changes the phase. The invention provides the pavement signal lamp control method between the adjacent intersections based on the particle swarm algorithm. By using the method, intersection vehicles and traffic efficiency of pedestrians are considered, reliability is high and the traffic efficiency is increased.
