Abstract

Through vehicle-mounted GPS date and map-matching technique, vehicle GPS locating point was matched within the corresponding traffic region by using circle split method, and the issue of acquisition of region traffic state was resolved. In this paper, technique process of acquisition of region traffic state based on map matching was sketched firstly, then region matching method was deeply researched, circle split method was put forward to perform region matching, and speed distribution curve was obtained by calculation, thus feasibility of circle split method was verified.
