摘要
分析了对行车线路固定的城区公交车实时定位的需求,介绍并讨论了一种简化的航迹推算定位办法,该办法通过不确定推理,综合利用了行驶路程的非精确测算结果和不确定的到站信息。
The requirement of fixed-line urban bus real-time positioning is analyzed, and then a simplified dead-reckoning positioning method is suggested and discussed, which is based on an uncertain reasoning approach that uses both nonprecise results of distance-measuring and uncertain messages about station-arriving.
