Abstract: A method and apparatus for adjusting channelization of a traffic intersection are proposed. The specific implementation of the method is: obtaining a first traffic characteristic of vehicles at each of a plurality of target positions in a process of vehicles in a target traveling direction traveling through the traffic intersection from upstream to downstream in a preset first time period; generating first traffic change information of the traffic intersection based on the first traffic characteristic at each of the plurality of target positions; and in response to that the first traffic change information satisfies a preset first change distribution, generating channelization adjustment information for non-motorized vehicle lanes of the traffic intersection.
