A method for determining a path, means

The present invention is in the field of path planning is disclosed a method of determining a path, the method comprising: obtaining the path of the road network; an event within the scope of the path covered by calculating the transition probability, wherein the transition probability is used to describe the event the probability of occurrence than might otherwise be incident in the range of the path covered transferred to the covered path range; according to the change of the path transition probability event. The present invention also discloses a corresponding method for indicating a patrol path, means for determining a path, the apparatus for indicating the patrol path. According to the technical solution provided by the invention can be optimized patrol path, to avoid wasting police force, better able to prevent the occurrence of adverse events.
