Towards a Distributed Multiagent Travel Simulation

Abstract

With the generalization of real-time traveler information, the behavior of modern transport networks becomes harder to analyze and to predict. It is now critical to develop simulation tools for mobility policies makers, taking into account this new information environment. Information is now individualized, and the interaction of a huge population of individually guided travelers have to be taken into account in the simulations. However, existing mobility multiagent and micro-simulations can only consider a sample of the real volumes of travelers, especially for big regions. With distributed simulations, it would be easier to analyze and predict the status of nowadays and future networks, with informed and connected travelers. In this paper, we propose a comparison between two methods for distributing multiagent travelers mobility simulations, allowing for the consideration of realistic travelers flows and wide geographical regions

Multiagent Simulation of Real-Time Passenger Information on Transit Networks

“…In the near future, we plan to run experiments with hundreds of thousands of passengers to verify, among other objectives, that the results reported in this paper are still valid with real volumes of passengers, and without adaptation of vehicles capacities. In this context, the distribution of the simulation platform on the cloud [7], [29] is an ongoing work [24]. We are also expanding this work to multimodal networks and studying the use of powerful dynamic pathfinding algorithms like D*Lite [20].…”

Impact of Travelers Information Level on Disturbed Transit Networks: A Multiagent Simulation

“…In the near future, we plan to develop scenarios with hundreds of thousands of passengers to verify that our results are coherent with real volumes of data. The distribution of the simulator on the cloud is also currently conducted [12]. Our second ongoing research concerns the optimization of the distribution of connected travelers over competitive paths and not send them all to the same itineraries.…”

Patterns to distribute mobility simulations

“…With the purpose of testing the efficiency of different ways to distribute the work load, we have, in a previous work [16], developed a multiagent travel simulator.…”

“…In a previous work [16], we have proposed distribution methods for a macroscopic simulator. Macroscopic simulations on the other hand use a function to calculate the vehicles speeds on a road, based on the number of vehicles on that road.…”
