PMSS Project Details


Project ID:FHWA-PROJ-11-0040
Project Name: VASTO — Evolutionary Agent System for Transportation Outlook
Status: Active
Last Name:Yang
First Name:David
Office: Office of Safety Research and Development
Team:Human Factors Team
Roadmap/Focus area(s): Travel Modeling
Project Description:The vision of this research emanates from an indepth understanding of both the limitation of existing traffic analysis capabilities and the potential advantage of a paradigm that creates synergy by integrating the simulation-based traffic analysis models and the agent-based simulation models.
Start Date: May 11, 2011
End Date: September 30, 2014
Goals: The key project objective is to integrate the agent-based modeling and simulation (ABMS) approaches seamlessly with emerging traffic simulation models to explore and expand new modeling capabilities.
Test Methodology: The model system will deliver a set of comprehensive toolboxes, consisting of a database, multimodal transportation simulation platform, and multiagent system simulation platform, plus critical visualization with efficient data analysis capability for fully visualizing the simulated system evolution. The visualization and data analysis capability will be driven by effective computational geometry, with spatial and temporal data queries based on a high-performance geographical information system engine, allowing the vast amount of raw simulation data to be processed, stored, analyzed, and displayed.
Partners: George Mason University; Role(s):
Expected Benefits:The proposed VASTO system will transform the understanding and modeling of the interactions among heterogeneous agents. Interaction mechanisms from behavioral aspects among the above agents are recognized as the “weakest link” in all existing transportation system models, especially with respect to the policy agent related feedback effects involved in the evolution of the system.
Deliverables:1. Name: Project report and simulation tool.
Product Type(s): Research report, Software, Technical report
Description: The deliverables are a detailed report documenting study efforts, findings, and recommendations, and a simulation tool developed from the project.
2. Name: A Primer for Agent-Based Simulation and Modeling in Transportation Applications
Product Type(s): Technical report
Description: This report attempts to clarify the concept of Agent-Based Simulation and Modeling (ABMS) studied in the transportation field with distinction of specified problems, model capabilities, strengths and weaknesses of ABMS scoped in different applied paradigms. The document is structured in a review format. The report also tries to connect ABMS and transportation problems in the social science paradigm, trying to apply ABMS characterized by social science methodology to tackle travelers’ behavioral decisions.
