[0021] A method for extracting traffic flow characteristics of highway starting and ending points:
[0022] Step 1: Collect vehicle travel information between the start and end of a highway in an area, and build a relational database with this information. The above information includes core data information and parameter configuration information. The core data information includes traffic zone tables, survey point tables, and OD records Table, cross-section flow table, parameter configuration information includes vehicle type classification table, vehicle owner classification table, cargo classification table, survey period classification table, OD record table is used to record the survey point, driving direction, vehicle type, starting point, and ending point of vehicle travel , Rated load, actual load information;
[0023] Step 2: Based on the information obtained in step 1, establish a set of sampling all-day O-D matrix P of survey point k, direction i, and vehicle type v ki...
