The invention discloses an urban traffic speed estimation method based on multi-source crowd sensing data, and the method obtains a final estimation speed through the steps of missing data filling, self-view speed aggregation, multi-view speed sum and the like based on roadside pedestrian data and road navigation data collected by a smart phone. According to the fine-grained large-scale urban traffic speed estimation method, speed estimation of all types of roads can be realized, including suburban road sections and small roads instead of only paying attention to the main road of the downtown. The method is based on data driving, additional devices do not need to be installed on the road, cost is low, universality is high, and compared with the prior art, the method has higher practicability, theoretical property and applicability and has important significance on improving traffic management and planning.
本发明公开了一种基于多源群智感知数据的城市交通速度估计方法,该方法基于智能手机收集的路侧行人数据和路上导航数据,经过缺失数据填充、自视图速度聚合和多视图速度同和等步骤得到最终的估计速度。本细粒度大规模城市交通速度估计方法能够实现所有类型的道路速度估计,包含了郊区路段与小路,而不是只关注市中心主路。本发明基于数据驱动,无需在道路上安装额外装置,成本低,普适性较强,与现有技术相比,具有更强的实用性、理论性与应用性,对改善交通管理和规划具有重要意义。
