The invention provides a traffic influence evaluation method and system based on an unmanned aerial vehicle, and relates to the technical field of road engineering. The traffic influence evaluation method based on the unmanned aerial vehicle comprises the following steps: S1, planning key data monitoring points in a research area, and inputting the key data monitoring points into an unmanned aerial vehicle system; in the research time period, data, including traffic flow data and intersection queuing data, on the monitoring points are automatically collected through the unmanned aerial vehicle; and S2, cleaning and processing the data acquired in the S1, fusing the data from other sources, calculating to obtain current traffic operation data, current traffic demand data and current traffic supply data in the research area, and finally forming a regional traffic model. By performing automatic data arrangement, data modeling and index analysis on the data acquired by the unmanned aerial vehicle, the evaluation efficiency can be remarkably improved, and the interference of subjective factors of evaluation personnel in the evaluation process is reduced. Meanwhile, evaluation process data can be digitally archived for subsequent retrieval and review.

    本发明提供一种基于无人机的交通影响评价方法及系统,涉及道路工程技术领域。该基于无人机的交通影响评价方法,包括以下步骤:S1、对研究区域内关键的数据监测点进行规划,并将其输入无人机系统。在研究时间段内,通过无人机自动采集监测点上的数据,包括交通流量数据、交叉口排队数据;S2、对S1中采集的数据进行清洗和处理,并将其它来源的数据进行融合,计算得到研究区域内现状交通运行数据、现状交通需求数据和现在交通供给数据,最终形成区域交通模型。通过可将无人机采集的数据进行自动数据整理、数据建模和指标分析,可显著提升评价效率,并降低评价过程中评价人员主观因素的干扰。同时评价过程数据可数字化存档,供后续调阅与复核。
