摘　　要： 对基于固定检测信息和浮动车GPS信息的路段行程时间估计方法进行介绍和分析,明确了对基于以上两种检测信息进行路段行程时间估计方法有重要影响的因素,并设计试验对影响因素进行量化分析。在影响因素量化分析基础上,讨论两种估计方法的适用条件。对影响因素进行组合分类,并在分类的基础上对两种估计方法采用加权融合进行处理,分析了最优权重的分配原则。最后,用试验数据对融合方法进行验证,结果令人满意。 A detailed description and analysis of the methods of travel time estimation based on the data collected by fixed detector and floating car were made. The main factors influencing the accuracy of the abovementioned two methods were clearly defined,and the experiment was designed to make quantization analysis of these influencing factors.Based on this analysis,the applicable conditions of the two methods were discussed.The influencing factors were grouped and classified,the weighting fusion method was applied to the two results of the abovementioned estimations,and the distribution principle for optimal weighted value was analyzed.At last,the abovementioned fusion method was verified by the experimental data.The result was encouraging.
