如何使用PostgreSQL中的GTFS数据快速查找中转站之间的行程时间
我有一个PostgreSQL数据库（带有PostGIS）和几个运输机构导入的GTFS数据（）。我已经根据距离确定了所有可能的转移地点，并用这些数据填充了一个表。我现在想找出该地区允许最多2次换乘的点之间的旅行时间。我创建了一个连接所有表的视图，以使我的查询更易于读取旅行时间。以下是我的看法：如何使用PostgreSQL中的GTFS数据快速查找中转站之间的行程时间,sql,postgresql,query-optimization,gtfs,Sql,Postgresql,Query Optimization,Gtfs,我有一个PostgreSQL数据库（带有PostGIS）和几个运输机构导入的GTFS数据（）。我已经根据距离确定了所有可能的转移地点，并用这些数据填充了一个表。我现在想找出该地区允许最多2次换乘的点之间的旅行时间。我创建了一个连接所有表的视图，以使我的查询更易于读取旅行时间。以下是我的看法： CREATE OR REPLACE VIEW trip_planning_data_view AS SELECT b.agency_id, i.agency_name, h.route_id, h.ro
