An urban tunnel variable lane dividing line control method, comprising: setting a distance between adjacent infrared detection apparatuses, and arranging a number n of infrared detection apparatuses side by side directly above the center of a lane of an urban tunnel; when a certain infrared detection apparatus in the urban tunnel detects a passing vehicle signal, extending the travelling direction, and if a number a of adjacent infrared detection apparatuses further along the travelling direction do not detect a passing vehicle signal within a time t, determining that the vehicle is a very slow vehicle, and changing a number m of LED indication lights which are fully illuminated to be illuminated at intervals. The urban tunnel variable lane dividing line control method can determine whether a very slow vehicle is present in a lane, and adjust a display state of a lane dividing line in an urban tunnel in real time, thereby increasing urban tunnel traffic efficiency, and preventing very slow vehicles from affecting urban tunnel traffic capacity.
