嘉兴市公交线路行程规划数据

公交线路行程规划数据通过集成公交数据与换乘站点基础信息，为乘客提供精准的换乘路线规划服务。输入出行起点与终点，系统即能计算并呈现最优换乘方案，包括换乘站点及换乘站数，同时实时更新公交运行状态，确保乘客能够高效、准确地完成换乘，从而实现公共交通系统的智能化与便捷化。对于每个站点，定义一个集合，包含该班次能够直接到达的所有其他站点，如果起始站点和结束站点均在这个集合中则不需要中转，是否需要换乘值为0，如需要换乘则为1。
如果需要中转换乘则将所有相关站点的集合进行交运算。具体步骤为：1)将所有站点的集合按照升序排序。2)同时遍历已排序的两个集合，找出它们之间的共同元素，即它们的交集R(si)和R(sj)，找出它们之间的共同元素，为它们的交集即中转站点。这个交集可以表示为：中转站点=R(si)∩R(sj)。3）根据求得的交集集合还原换乘路径：对于交集中的起始站点，我们记录从起始站点到换乘站点的站数，以及换乘站点到结束站点的站数，还原出首趟站数和二趟站数。
通过比较获得的不同路径的换乘次数、站数等数据，对换乘路径进行筛选，得到合适的行程规划。

Bus route trip planning data integrates bus operation data and basic information of transfer stations to provide passengers with accurate transfer route planning services. By inputting the travel origin and destination, the system can calculate and present the optimal transfer plan, including transfer stations and the number of transfer stops, while updating real-time bus operation status to ensure passengers can complete transfers efficiently and accurately, thereby realizing the intelligence and convenience of the public transportation system.

For each station, define a set containing all other stations directly reachable by the corresponding bus service. If both the origin station and destination station are included in this set, no transfer is needed, and the transfer required flag is set to 0; otherwise, the flag is set to 1.

If transfer is required, perform set intersection operations on the sets of all relevant stations. The specific steps are as follows: 1) Sort the sets of all stations in ascending order. 2) Traverse the two sorted sets simultaneously to find their common elements, namely their intersection R(s_i) ∩ R(s_j), which are the transfer stations. This intersection can be expressed as: Transfer Stations = R(s_i) ∩ R(s_j). 3) Restore the transfer route based on the obtained intersection set: For the origin station in the intersection set, record the number of stops from the origin station to the transfer station and the number of stops from the transfer station to the destination station, thus restoring the stop counts for the first and second bus trips.

By comparing data such as the number of transfers and stops of different obtained routes, we screen the transfer paths to obtain appropriate trip plans.
