摘要
公交线路覆盖率是评价城市地面公交发展水平的重要指标,由于近年来公交系统的快速发展,导致早期规划数据根本无法反映最新的实际线路覆盖率,传统上,实际线路覆盖率只能通过地图测量等人工、半人工方式来完成,效率低、精度差,因此作为智能公交系统的一部分,迫切需要一种公交线路覆盖率的实时计算方法。基于这一需求,本文提出了一种基于公交GPS数据的公交线路覆盖率计算方法,该算法以高精度地图匹配为核心,通过数据点抽稀、地图匹配校正、采样点-路段转换等几个步骤,对公交线路长度进行计算。实验结果表明,本文算法具有速度快,准确度高的优点,在实际应用中,只需要导入城市公交的部分GPS数据,就可以迅速准确地计算公交线路的实际长度,为公交发展规划和评价提供了一种有效的工具。
Bus coverage rate is an important indicator for evaluating the development level of urban ground transportation.Due to the rapid development of public transportation system in recent years,the early planning data can not reflect the latest actual line coverage.Traditionally,the actual line coverage can only use Manual and semi-manual methods such as map measurement,but these methods are performed with low efficiency and poor precision.Therefore,as part of the intelligent public transportation system,a real-time calculation method for bus line coverage is urgently needed.Based on this demand,this paper proposes a bus line coverage calculation method based on GPS data.The algorithm takes high-precision map matching as the core,through data thinning,map matching correction,sampling point-segment conversion and so on steps to calculate the length of the actual bus line.The experimental results show that the proposed algorithm has the advantages of high speed and high accuracy.In practical applications,only need to import part of the GPS data,the actual length of the bus line can be calculated quickly and accurately.This algorithm provides an effective tool for public transport development planning and evaluation.
