An example method includes obtaining, by a first local traffic control unit (TCU), a traffic application type and first traffic information. The first local TCU can then determine an interaction coverage area based on the traffic application type and the first traffic information. The first local TCU can then determine a first area and send the traffic application type and the first traffic information to a global TCU, where a second local TCU is a local TCU adjacent to the first local TCU, where the first area is at least one overlapping area between a management area of a third local TCU and the interaction coverage area, and where the third local TCU is a local TCU not adjacent to the first local TCU.
