A JADE implementation of a real agent application is linked to a virtual traffic domain to test control behaviour of traffic semaphores. Mixing reality and virtual environments is expected to foster the development of new generation of urban transport solutions. First experiments were carried out, which demonstrated the feasibility of the ...

It is definitely a difficult task and experience has shown there is still a long (and uncertain) road ahead. Most problems are often tackled on an individual bases and inte- grating different perspectives on the same analysis process is tough. Trading off between realism and too much abstraction is another important issue to overcome. In this work we bring this discussion forward and propose a multi-agent model of the domain where inte- gration is ascribed to the way the environment is represented. We focus on road transport in urban areas, which is already a complex do- main on its own right, and discuss on the role of the environment dynamics in supporting a truly emergent behaviour of the system. A physical communication model is proposed to explore the different perception abilities of each single agent as the basis for different in- teractions and overall system perform...

The population of drivers is represented as a community of autonomous agents, and travel demand results from the decision-making deliberation performed by each individual of the population as regards route and departure time. A simple simulation scenario was devised, where pretrip information was made available to users on an individual basis so that its effects at the aggregate level could be observed. The simulation results show that the overall performance of the system is very likely affected by exogenous information, and these results are ascribed to demand formation and network topology. The expressiveness offered by cognitive approaches based on predicate logics, such as the one used in this research, appears to be a promising approximation to fostering more complex behavior modelling, allowing us to represent many of the mental aspects involved in the deliberation process.

A framework based on the concept of service-oriented architectures (SOA) to support the assessment of vehicular ad-hoc networks (VANET) is herein presented. Concepts related to SOA, as well as technologies that allow real-time data acquisition and dissemination within urban environments, and simulation tools to aid the simulation of VANET were preliminarily studied. A two-layered architecture was specified on the basis of the requirements for our simulation framework resulting in the specification of a multi- ...

Traditional approaches lack adequate means to foster integrated analyses of transport systems either because they are strict in terms of purpose or because they do not allow multiple users to dynamically interact on the same description of a model. The use of a common geographical data model of the ...

The information collected from such analysis is used to better understand the difficulties of trainees, players or even entire teams and formulate adequate training and strategic plans. Usually this evaluation is too self contained and does not explore the many tools there are available nowadays. This paper proposes a simulation tool to tackle this problem and ...

As updating digital maps by the usual means is a highly expensive and time consuming task, GPS points gathered by existing navigation devices can be used to compare the existing real road network with the digital one. This paper describes an approach to update digital maps through the use of GPS points obtained during users' journeys as a means to identify map incongruence. Detection of new roads ...
