针对现代有轨电车不同子系统的车辆定位需求，通过对不同定位技术方案的综合分析，提出最适用于有轨电车的“计轴+感应环方式+信标定位”、“GPS/BD组合+信标定位”、“信标定位”等组合定位方式。

According to the demand of modern tram vehicle positioning of different subsystems, through a comprehensive analysis of the scheme of different positioning, authors proposed the positioning modes which are the most suitable for the tram, such as "axle counter + induction loop + beacon positioning", "GPS/BD + beacon positioning", "beacon positioning" and the combination of fixed positioning.
