道路交叉点 meaning in English

carrefour
common point
road crossing
road junction

Theory analyzing and simulations show that : when target is on road , on road - junction , or on the transition from on - road to off - road ( from off - road to on - road ) , the performance of tracking algorithm using extended map - tuned variance method is improved obviously
理论分析和仿真研究表明，当目标在道路上或者道路交叉点，或者目标从道路到道路外及从道路外到道路上的过渡过程时，目标跟踪性能得到改善。
We present " c - imm extended map - tuned variance method " to combine c - imm and extended map - tuned variance method . simulations show that : the performance of target tracking is improved by using c - imm extend map - tuned variance method when target is on road or junction
理论分析和仿真表明，基于多模型的“ c - imm扩展地图调整方差法”对于目标在道路交叉点时，或者目标在道路上匀速运动时，跟踪性能有所改进。
