The invention discloses a road network marking method for traffic crossing state indication, comprising the following steps: step 1, acquiring road network topology information of a city; step 2, acquiring information of next crossing i; step 3, judging whether the crossing i has a traffic ban sign, jumping to step 4 if the crossing i has a traffic ban sign, or jumping to step 6; step 4, splitting the crossing i into multiple low-dimensional nodes; step 5, setting the traffic direction and load information between adjacent low-dimensional nodes; step 6, judging whether all crossings are traversed, jumping to step 7 if all the crossings are traversed, or jumping to step 2; and step 7, performing updating to obtain the road network topology of the city. According to the method of the invention, high-dimensional nodes with traffic ban features are reduced to low-dimensional nodes, and weights of internal edges between the low-dimensional nodes are connected to represent stop signs, thereby ensuring flattening of an algorithm and improving the computational efficiency and speed of the algorithm.
