car sampling meaning in Chinese

槽车取样
矿车取样

Secondly , the identification algorithms of road traffic status are studied including methods of determining floating car sample sizes which are based on “ the relationship between floating car sample sizes and accuracy of traffic information detection ” and “ the relationship between floating car sample sizes and requirement of road network information detection ” . the road traffic identification algorithm grounded on the journey - time is analyzed . besides , road traffic identification algorithm based on average speed is put forward and the validity of these two methods is analyzed in the thesis
主要工作包括:从“浮动车数量与交通流信息检测准确性关系” 、 “浮动车样本数量与路网全方位信息检测需求关系”两方面对浮动车数量确定方法进行研究,给出了算法模型;同时,分析了基于行程时间的道路交通判别算法,提出了基于指数平滑法的平均瞬时速度道路交通判别算法,并对两种算法的有效性进行分析比较。
