The invention discloses a road section online travel time estimation method based on multi-source data fusion. The method comprises the steps of 1, generating a corresponding road network topological relation for element composition and spatial distribution in a researched road network range; step 2, preprocessing the bayonet and radar data, and filtering anomalies and repeated records; 3, setting interval upstream and downstream license plate matching time window rules, matching license plates, calculating to obtain single vehicle travel time, and extracting free flow travel time of each interval; dividing the state of a single vehicle in the current calculation period interval, counting the sample size of the current calculation period, and judging the running state of the current calculation period interval; 4, calculating the travel time of the current period interval; and 5, splitting the interval travel time to the road sections to obtain online travel time estimation corresponding to the road sections. According to the method and the system, sufficient mining and utilization of data resources under the conditions of partial loss of checkpoint data and small samples are realized, and the space-time integrity, effectiveness and real-time performance of travel time of each road section in a road network are improved.
本申请公开了基于多源数据融合的路段在线行程时间估计方法，包括：步骤一、对所研究路网范围内要素组成及其空间分布生成相应路网拓扑关系；步骤二、对卡口和雷达数据进行预处理，过滤异常以及重复记录；步骤三、设置区间上下游车牌匹配时间窗规则，对车牌进行匹配并计算得到单车行程时间，提取各个区间自由流行程时间；划分当前计算周期区间单车状态，统计当前计算周期样本量，对当前计算周期区间运行状态进行判别；步骤四、计算当前周期区间行程时间；步骤五、区间行程时间拆分到路段，得到对应于路段的在线行程时间估计。本申请实现卡口数据部分缺失与小样本情况数据资源的充分挖掘与利用，提升路网内各路段行程时间时空完整、有效与实时性。
