The purpose of multi-modal route planners is to provide the user with the optimal route between trip start and destination, where the route may utilize several transportation modes including public transportation. The optimal route is defined over a set of evaluation criteria considered by the user during the route selection process. Especially in the case of multi-modal transportation, numerou...

We study multi-modal route planning allowing arbitrary (meaningful) combinations of public transportation, walking, and taking a car / taxi. In the straightforward model, the number of Pareto-optimal solutions explodes. It turns out that many of them are similar to each other or unreasonable. We introduce a new filtering procedure, Types aNd Thresholds (TNT), which leads to a small yet represen...

The paper focuses on composite multistage decision making problems which are targeted to design a route/trajectory from an initial decision situation (origin) to goal (destination) decision situation(s). Automobile routing problem is considered as a basic " physical " metaphor. The problems are based on a discrete (combinatorial) operations/states " design/solving space " (e.g., digraph). The d...

Route planners are tools that support the navigator in selecting the best route between two locations. Solving a route choice problem involves sorting and ranking of alternatives according to underlying evaluation criteria and decision rules. Using an appropriate classification of route selection criteria in the user interface is an important ingredient for user friendly route planners. The pap...

One of the current challenges in urban planning concerns the urban transportation involving multi-mode transportation. One of the ways to evaluate different situations in order to make decisions of how, when and where to invest is using multimodal traffic simulation. This paper presents a review about multimodal traffic simulation, identifying the state of art and directions for future work. Ke...

A specification, formulisation and implementation for multiobjective optimised route planning on a transport network is described. Transportation problem search spaces are large and often complex, involving many (independent) variables. Travellers often settle for any journey specification satisfying some weak set of conditions. The approach described provides provably optimal journey specifica...

Rapid development of information and communication technologies (ICT) enables complete distribution of traveler information to end-users through the whole travel. European intelligent transportation system (ITS) architecture defines traveler information as specific functional area, and it comprises static and dynamic information about transport network condition, traveler information services a...

The optimal path problem is an important topic in the current geographic information system (GIS) and computer science fields. Dijkstra algorithm a commonly used method to find shortest path, which usually least cost from single source. Based on analysis research of traditional algorithm, this paper points out problems optimizes it improve its storage capacity operation efficiency. Then, combin...
