基于基站的高速公路车辆定位技术

摘要

Based on the comprehensive study of the positioning method of the base station,the base station positioning technology is applied to the Services LBS (Location-Based).Through the vehicle running on the highway through a continu-ous different base station,the proposed algorithm for the location of highway vehicles can effectively calculate the direction of the traj ectory.Combined with a single base station coverage and a highway geometry,the geometric relationship is used to comprehensively analyze the running direction and position of the vehicles on the expressway.%通过对基站定位技术的综合研究,旨在将基站定位技术应用于高速公路车辆位置服务中.通过高速公路上车辆行驶经过连续不同的基站,提出一种针对高速公路车辆位置定位的算法,能够有效地推算出车辆的行驶方向轨迹,结合单基站所覆盖范围与高速公路形成的几何图形,利用几何关系综合分析出高速公路上车辆的行驶方向及位置.
