Abstract: A route planner for a transportation network is disclosed. The route planner generates k suggested routes based on a user query using a diversified k shortest routes technique. The diversified k shortest routes techniques analyzes a transportation graph and suggests k routes to the user. The diversified k shortest routes can provide a user with options to take the next best route if they miss the optimal one. These options also include other preferences, such as less number of transfers, as long as they are reasonable in terms of total travel time. The suggested routes take into account travel calendars, as well as location-to-location queries which require geocoding and reverse geocoding capabilities. Transfers between different types of transportation services such as train and bus are also supported.

The optoelectronic unit has a central line in a top view, a top surface, and a bottom surface. The second metal layer is formed on the top surface, and has an extension portion crossing over the central line and extending to the first metal layer. The conductive layer covers the first metal layer and the extension portion. The transparent structure covers the bottom surface without covering the top surface.

Abstract: A computer-implemented technology for planning routes is described herein. In accordance with one aspect, travel data of commuters of a transportation network are provided. Continuous distributions of travel time and waiting time are generated from the travel data. The continuous distributions of travel time and waiting time are associated to a transportation graph of the transportation network. The transportation graph includes nodes corresponding to stops of the transportation network and edges interconnecting the nodes. Travel time and waiting time are associated as costs of the edges in the transportation graph. In response to receiving input parameters, expected costs of candidate routes in the transportation graph are determined in accordance with a modified multi criteria shortest path technique. The modified multi criteria shortest path technique invokes a subroutine to retrieve accurate costs of routes based at least on the costs of the edges in the transportation graph.
