Abstract: A public transit travel planning system and methodology that uses an extensive pre-processing approach of transit information prior to query time on order to determine optimal public transit routes for journeys. At query time, since the transit information has already been processed by the system, very little computation is needed in order to fulfill the query. The system then provides users with public transit directions in response to the queries for public transit journeys.

Abstract: Systems and methods are provided for the determination of routes from, for instance, travel segment network data associated with different data versions. More particularly, a request can be received for a route from an origin to a destination. Graph data modeling a travel segment network for a geographic region associated with the origin and for a geographic region associated the destination can be accessed. The graph data can preserve boundary nodes for visiting during a search (e.g. a contraction hierarchies style search) for a shortest path through the graph data. The reach value of a boundary segment can be considered in identifying boundary segments to be visited during the shortest path search through the graph data. The route can be determined based at least in part on the shortest path.
Abstract translation: 提供系统和方法用于确定例如与不同数据版本相关联的旅行段网络数据的路线。 更具体地，可以接收从原点到目的地的路线的请求。 可以访问与原点相关联的地理区域以及与目的地相关联的地理区域的旅行分段网络的图形数据建模。 图形数据可以保留用于通过图形数据的最短路径的搜索期间的边界节点（例如收缩层次样式搜索）。 在通过图形数据的最短路径搜索期间，可以考虑边界段的到达值来识别要访问的边界段。 该路由可以至少部分地基于最短路径来确定。

Abstract translation: 一个公共交通旅行规划系统和方法，在查询时间之前使用广泛的过境信息预处理方法，以确定最佳的公共交通路线。 在查询时，由于传输信息已被系统处理，所以为了满足查询需要很少的计算。 该系统随后向公众提供公共交通路线，以响应公共交通工具的查询。
