The invention discloses an optimal detector layout method for regional traffic carbon examination, which belongs to the technical field of traffic, and comprises the following steps of: firstly, finding out a highest-cost sub-graph which does not need to install a detector in a road network, and then in the remaining road sections, fully utilizing the detection range characteristics of novel detection equipment at an intersection so as to obtain the optimal detector layout. Detector layout and point selection are completed step by step according to nodes, road section groups and single road sections from the low construction cost to the high construction cost, compared with an existing detector layout method, the method faces traffic carbon examination to obtain the requirement for accurate flow and vehicle type distribution of all the road sections, and the layout has higher economical efficiency and practicability from the perspective of the construction cost; traffic flows of an entrance lane and an exit l
