城市交通系统面临着安全、拥堵造成的延误、车辆尾气污染以及易受自然和人为灾害影响等方面的重大挑战。复杂、集成的传感器/执行器系统有可能在缓解这些问题方面取得重大进展。通过自组织无线网络的车到车通信为创新应用提供了新的机会，减少了公共基础设施投资。该项目将探索实现智能交通系统(ITS)中传感器和执行器系统的快速评估和集成的基于模拟的试验台，并利用该试验台探索支持其应用的数据网络的体系结构替代方案。将使用一种集成的分布式仿真方法，重点是交通基础设施、有线和无线通信网络以及分布式计算应用的可互操作仿真。该项目将纳入在亚特兰大大都市区运行的仪表化车辆池中的数据，提供有关车辆位置、速度和加速度等的每秒传感器数据；亚特兰大地区道路传感器的数据也将用于模型和场景开发以及模拟验证。试验台的研究将集中在开发一种模块化的联邦仿真/仿真方法，使用软件底板来连接仿真和数据。

Urban transportation systems face important challenges concerning safety, delays due to congestion, pollution from vehicle emissions, and vulnerability to natural and man-made disasters. Sophisticated, integrated sensor/actuator systems offer the potential to make significant inroads in alleviating these problems. Vehicle-to-vehicle communication via ad hoc wireless networks present new opportunities for innovative applications with reduced public infrastructure investments. This project will explore the realization of simulation-based test beds for rapid evaluation and integration of sensor and actuator systems in Intelligent Transportation Systems (ITS), and use this test bed to explore architectural alternatives for data networks supporting ITS applications. An integrated distributed simulation approach will be utilized, focusing on interoperable simulations of transportation infrastructures, wired and wireless communication networks, and distributed computing applications. The project will incorporate data from a pool of instrumented vehicles operating in the Atlanta metropolitan area providing second-by-second sensor data concerning the vehicle's location, velocity, and acceleration, among others; data from road sensors in the Atlanta area will also be used for model and scenario development and validation of simulations. Test bed research will focus on developing a modular, federated simulation/emulation approach using a software backplane to interface simulations and data.
