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。
Based on the fixed detection information and floating car GPS information of the link travel time estimation methods are introduced and analyzed clearly identified based on the above two pieces of information on the link travel time estimation methods have a significant impact factors and design experiments to quantify the impact of factors analysis. Based on the quantitative analysis of influencing factors, the applicable conditions of the two estimation methods are discussed. The influencing factors were classified and combined. Based on the classification, the two methods were weighted by weighted fusion, and the principle of optimal weight distribution was analyzed. Finally, the experimental data to verify the fusion method, the results are satisfactory.
