The invention discloses an urban road network boundary control and path distribution combined control method. Comprising the following steps: (1) obtaining geometric data, region division data, a macroscopic fundamental diagram function of each region, a critical value of the number of vehicles, a saturation flow rate of a region boundary intersection, geometric data and selectable phases, a macroscopic control step length and a microscopic control step length of a road network in a target time period; (2) taking a region-based road network as a research object, obtaining the total number of vehicles, vehicle positions and destinations in each region, and constructing and solving a boundary control and path distribution joint optimization model of the multi-region network; (3) taking each region boundary as a research object, obtaining the number of vehicles queuing at an entrance lane and an exit lane of the region boundary intersection, and determining the optimal phase of the region boundary intersection; and (4) taking each area as a research object, obtaining vehicle positions, destinations and selectable path sets in the areas, constructing and solving a path distribution model, and distributing specific paths for the vehicles in the areas.
