PROJECT SUMMARYAlthough the investment and the interest in Intelligent Transportation Systems(ITS) is growing exponentially, robust real-time on-line traffic controlstrategies that can effectively use this ITS infrastructure do not exist yet.Recent advances in the area of mathematical control theory coupled with theavailability of real-time traffic data present major opportunities for thedevelopment and implementation of robust traffic responsive real-time feedbackcontrol models and strategies. This integrated research and education projecthas the following objectives:1. Development of feedback based on-line traffic control strategies that can beused for real-time traffic management during recurrent and non-recurrentcongestion.Previous research in the area of traffic control mostly focused on the use ofsimulation / optimization based approaches. However, these traditional modelsare not generally applicable to real-time systems due to their very highcomputational costs and robustness requirements of real-time traffic controlsystems. The use of the feedback control design methodologies that can make useof real-time data collected by traffic sensors, constitutes an exact match withthe requirements of ITS, due to the capability of feedback models to respond inreal-time to the deviations of the system from its desired behavior.2. Development of Virtual Interactive Traffic Simulation control on the Internet(VITSI) toolbox and use of real-time traffic data for laboratory testing andvalidation.VITSI toolbox will be developed using several programming languages includingC/C++ and JAVA depending upon the computational requirements of the modules tobe developed. The goal for developing VITSI is to provide researchers andstudents with a flexible and specialized traffic simulation and control designtool set they can use for the development, testing and validation of differentreal-time traffic control strategies. On-line traffic data acquired by RutgersIntelligent Transportation (RITS) laboratory coupled with VITSI toolbox willalso be used to test and validate developed models. This real-time traffic datawill be mainly obtained from ITS facilities in New Jersey.3. Introduction of the results of the proposed research activities into theundergraduate and graduate level traffic control courses through the use of theproposed VITSI toolbox and traffic data acquisition and processing capabilitiesat the recently established Rutgers Intelligent Transportation Systems (RITS)laboratory.With the advent of ITS, on-line traffic control design, testing, andimplementation has become one of the fast growing areas of traffic engineering.However, feedback control techniques have not yet been effectively introducedinto the traffic engineering education programs. This research project willdesign an integrated interdisciplinary research-education program that willincorporate feedback control techniques into both graduate and undergraduatetraffic engineering classes. At the heart of the education efforts, there willbe the use of VITSI toolbox concept coupled with the on-line traffic dataacquisition and processing capabilities of the RITS laboratory. VITSI toolboxwill be specifically designed to encourage the use of Internet based hands-ontools for effective teaching, learning, and research activities, and willcomplement RITS as a new research and education tool that does not currentlyexist.

项目摘要虽然对智能交通系统 (ITS) 的投资和兴趣呈指数级增长，但能够有效利用该 ITS 基础设施的强大实时在线交通控制策略尚不存在。数学控制理论领域的最新进展与实时交通数据的可用性为开发和实施强大的交通响应实时反馈控制模型和策略提供了重大机会。 这个综合研究和教育项目有以下目标： 1．开发基于反馈的在线交通控制策略，可用于经常性和非经常性拥堵期间的实时交通管理。交通控制领域的先前研究主要集中于使用基于模拟/优化的方法。 然而，这些传统模型由于计算成本非常高以及实时交通控制系统的鲁棒性要求，通常不适用于实时系统。 反馈控制设计方法可以利用交通传感器收集的实时数据，由于反馈模型能够实时响应系统与其自身状态的偏差，因此与ITS的要求完全匹配。期望的行为.2。开发互联网上的虚拟交互式交通仿真控制（VITSI）工具箱，并使用实时交通数据进行实验室测试和验证。VITSI工具箱将根据待开发模块的计算要求，使用包括C/C++和JAVA在内的多种编程语言进行开发发达。 开发 VITSI 的目标是为研究人员和学生提供灵活且专业的交通仿真和控制设计工具集，可用于开发、测试和验证不同的实时交通控制策略。 罗格斯大学智能交通 (RITS) 实验室获取的在线交通数据与 VITSI 工具箱相结合也将用于测试和验证开发的模型。 该实时交通数据将主要从新泽西州的ITS设施获得。3．通过使用拟议的 VITSI 工具箱以及最近建立的罗格斯智能交通系统 (RITS) 实验室的交通数据采集和处理功能，将拟议研究活动的成果引入本科生和研究生水平的交通控制课程中。随着 ITS 的出现，线路交通控制的设计、测试和实施已成为交通工程快速发展的领域之一。然而，反馈控制技术尚未有效地引入交通工程教育项目中。 该研究项目将设计一个综合的跨学科研究教育计划，将反馈控制技术纳入研究生和本科生交通工程课程。 教育工作的核心是使用 VITSI 工具箱概念以及 RITS 实验室的在线交通数据采集和处理能力。 VITSI 工具箱将专门设计用于鼓励使用基于互联网的实践工具进行有效的教学、学习和研究活动，并将作为目前尚不存在的新研究和教育工具对 RITS 进行补充。
