嘉兴市公交站点实时车辆数据

通过车载GPS终端的实时定位，并依据线路站点位置数据匹配上正确的站点，实时更新并显示每辆公交车的离站站数和最近一班离站距离以及首末班次信息。乘客可以通过智能手机上的应用程序或是公交站台的电子站牌获取即将到来的公交车的具体信息，并且提供该公交车的首末班次时间，以便规划出行时间，避免长时间等待或错过末班车。基于线路站点列表的基础数据，通过构建站点间的逻辑序列，确立了各站点的进出顺序、前后关联关系及上下行的一致性规则。利用车载GPS终端实时采集的经纬度数据，并结合站点经纬度数据，对当前线路上车辆与各站点距离的精确测定。对于某一个站点Si（其中i从1到n，n是站点总数），计算车辆当前位置P与站点Si之间的距离di，通过使用Haversine公式得到的系数a，带入公式得到离站距离=2Ratan2(√ai,√(1-ai))。得到了该车辆与站点的距离结果。通过实际需求的站点名称比对车辆上一次进出站点的上下行关系，排除了非当前行驶方向的站点。并根据方向计算改车辆距离该站点的离站站数即最近一班离站站数，最后依据线路站点列表的基础信息，明确了该线路的始发站与终点站，并提供首末班次的具体时间，完成整个车辆到离站数据。

Using real-time positioning data from on-board GPS terminals and matching against line station location data to identify the correct stop, this dataset updates and displays in real time the number of stops away from the current stop, the distance to the nearest departing bus, and first/last service information for each bus. Passengers can access detailed information about upcoming buses via smartphone applications or electronic stop signs at bus stops, as well as the first and last departure times of these buses, to plan their travel schedules, avoid prolonged waiting or missing the last bus.
Based on the basic data of the line station list, the logical sequence between stations is constructed, establishing the entry/exit order of each station, the forward-backward association relationship, and the consistency rules for up/down directions. Using longitude and latitude data collected in real time by on-board GPS terminals, combined with station longitude and latitude data, the precise distance between vehicles on the current line and each station is measured. For a given station S_i (where i ranges from 1 to n, n is the total number of stations), the distance d_i between the vehicle's current position P and station S_i is calculated. The coefficient a obtained via the Haversine formula is substituted into the formula: Departure Distance = 2R·atan2(√a_i, √(1-a_i)) to derive the distance between the vehicle and the target station. By comparing the up/down direction of the vehicle's last entry/exit station with the actual required station names, stations not in the current driving direction are excluded. The number of stops away from the current station for the vehicle, i.e., the number of stops to the nearest departing station, is calculated based on the driving direction. Finally, based on the basic information of the line station list, the origin and destination stations of the line are identified, and the specific first and last service times are provided, completing the entire vehicle-to-stop distance dataset.
