Automatic toll collection method based on two-dimensional space

The invention discloses an automatic toll collection method based on a two-dimensional space, which includes the steps: A, defining a transaction range according to lane layout, and constructing a transaction matrix in correspondence to the defined transaction range; B, recognizing positions of vehicles in the transaction range, determining matrix elements B corresponding to the vehicles according to vehicle position information and the correspondence in the step A, and filling vehicle identifiers into the matrix elements B; C, recognizing positions and transaction states of OBUs (on board units) in the transaction range, determining matrix elements C corresponding to the OBUs according to position information and the correspondence in the step A, filling the transaction states into the matrix elements C; and D, setting transaction logic for selectively handling the vehicles according to the transaction matrix filled with the vehicle identifiers and the transaction states.
