We propose algorithms to compute a full Pareto set and then score the solutions in a postprocessing step using techniques from fuzzy logic, quickly identifying the most significant journeys.  ...  We study the problem of finding multimodal journeys in transportation networks, including unrestricted walking, driving, cycling, and schedule-based public transportation.  ...  Restricting Walking. Consider our simple scenario of walking and public transit.  ...

We show how to compute such guidebook routes efficiently and with provably good quality. An evaluation on real-world data shows that few guidebook routes usually suffice for good coverage.  ...  Public-transportation route-planning systems typically work as follows. The user specifies a source and a target location, as well as a departure time.  ...  Introduction When planning a trip with a public-transport information system, the standard setting is to specify a source location and a target location, and a departure time and date.  ...

We consider the problem of Pareto-optimal route planning in public-transit networks of a whole country, a whole continent, or even the whole world.  ...  Transfer Patterns, a state-of-the-art technique for route planning in transit networks, achieves excellent query times, but the space consumption is large and the preprocessing time is huge.  ...  This works because the state of the art has advanced to such a point that public-transit routing on whole metropolitan areas can be done with very fast query processing time and reasonable preprocessing  ...

Second, an anonymous Pareto-improving pricing scheme in a transportation network with a discrete set of value of times (VOTs) for several distinct user classes is proposed and solution algorithms are developed  ...  Despite the successes of pricing projects worldwide and growing government support, congestion pricing remains largely unappealing to the general public, and it is this lack of public support that impedes  ...  Furthermore, although tolls are charged on restricted users only, their route choices may influence route choices of non-restricted users and achieve better system performance.  ...
