The invention discloses a method for determining the logistics distribution distance of product oil, and the method comprises the following steps: 1) setting and uploading measurement parameters according to the function guidance of an online service; 11) setting map coordinates of a point to be measured; 12) setting a measurement data type; 2) the user sets and uploads a map route map of the measurement site; 21) setting a starting point and a terminal point; 22) setting a path point, and informing a user of the path trend of the two places of the online service measurement through the path point; 23) performing map measurement and outputting a measurement result; 231) analyzing and measuring the path data of the distance route, carrying out subdivision processing on the route according to the vector characteristics of the route, and carrying out subdivision processing on the route by the online service to different degrees according to different characteristics of the route. According to the method and the system, re-measurement work does not need to arrange vehicles and personnel to go out of a highway for actual measurement any more, so that the efficiency of the re-measurementwork is greatly improved, and the updating period of the transport distance data is shortened.
