The invention provides an expressway and city local road connection section control strategy optimization method based on a particle swarm optimization algorithm. The method comprises the steps of obtaining road section traffic flow and road network structure data of a research object expressway and adjacent city roads; abstracting the road network, and constructing a road network directed graph; setting constraints, and constructing a mathematical model taking the minimum travel time as a target function; solving the mathematical model by using a particle swarm optimization algorithm to obtain a feasible solution, namely a group of traffic control strategies; traffic flow distribution calculation is carried out according to the obtained traffic control strategy, iterative optimization is carried out according to a calculation result, and a better feasible solution is generated; iteration is repeated until the termination condition is met, and an optimal feasible solution is obtained. According to the invention, joint optimization of ramp control, lane use and traffic signal control strategies is realized through the particle swarm optimization algorithm, so that traffic congestion is reduced and traffic passing efficiency is improved.
