Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...

Computing travel plans for desired trips in public transportation systems is not exactly the same as finding a shortest driving path in a given area. Path planning in the context of public transportation systems must consider the route constraint that public vehicles serve on particular paths and that passengers cannot order the drivers to change the bus routes. Explicit representation of the r...

This research attempts to build a framework for determination of optimal routes for hazardous material transportation. Previous works have suggested incorporation of many conflicting objectives in the analysis, such as travel cost, population exposure, environmental risk or security concerns. Multiplying the number of objectives leads to complex shortest path problems that often have several ef...

Many interesting route planning problems can be solved by computing shortest paths in a suitably modeled, weighted graph representing a transportation network. Such networks are naturally road networks or timetable networks of public transportation. For large networks, the classical Dijkstra algorithm to compute shortest paths is too slow. And therefore have faster algorithms been developed in ...

The TRANSIMS (TRansportation ANalysis and SIMulation System) project is a large scale transportation system project produced by Los Alamos National Laboratory for transportation planning. In TRANSIMS, all processes are represented on the microscopic level. These processes range from decisions of individuals about their daily activities all the way to signal operations and traffic movements. TRA...

Route bus system is fundamental transportation device for aged people, and have important role in every province. However passengers decreases year by year. Therefore we have developed the shortest path searching system called “BUS-NET” to sustain the public transport. Here, generation of timetables is picked up. In general, it is considered as very simple problem, however the route bus system ...

Effective management of the vehicles plays an important role in transportation sector. There are some novel approaches in software engineering which can be used to dynamically control the trucks. One of the example technologies is multi-agent systems. Multi-agent-based technologies could be used for truck dispatching in real time. The trucks in such systems have their own transportation plan an...

Following on from our work concerning travellers’ preferences in public transportation networks (Wu and Hartley, 2004), we introduce the concept of stochasticity to our algorithms. Stochasticity greatly increases the complexity of the route finding problem, so greater algorithmic efficiency becomes imperative. Public transportation networks (buses, trains) have two important features: edges can...
