The invention discloses a crossing turning flow analysis
system and method based on base-
station signaling data, and relates to the field of road flow analysis. The
system comprises a data collectionmodule, a storage module and a
processing module. The data collection module is used to obtain
latitude and
longitude information of a crossing and
latitude and
longitude information of all base stations of an area to which the crossing belongs, and uploads the
latitude and
longitude information; the storage module is used to store the latitude and longitude information; and the
processing modulecalculates distances between the base stations and the crossing according to the latitude and longitude information of the information and the latitude and longitude information of the base stations,selects all base stations whose distances to the crossing is greater than a threshold alpha and lower than a threshold beta as determining base stations, and divides the determining base stations intoidentification clusters in different directions. The threshold alpha ranges from 100 to 300m, and the threshold beta ranges from 900 to 1200m. Thus, proper base stations can be select to form
base station clusters so as to determine vehicle turning.
