Traffic congestion continues to be one of the most pressing problems facing urban America. Intelligent transportation systems (ITS) provide the systems perspective needed for sustainable solutions to urban mobility problems. During the final decade of the 20th century, hundreds of millions of dollars were invested in ITS surveillance, detection, and traveler information technologies. In this first generation ITS there remains a largely untapped potential to exploit the wealth of remotely sensed data for automated, time critical management and control. Multi-scale system-wide forecasting and state estimation is required for next generation ITS to support proactive rather than reactive transportation system management. This career development plan will provide an integrated research and education framework for system-wide traffic condition monitoring and state estimation for intelligent transportation systems. Research activities will include: (1) development of a system-wide ITS traffic condition monitoring and forecasting framework, (2) seasonal ARIMA based Kalman filtering for univariate forecasts, (3) application of continuum traffic flow theory to one-step system forecasts, and (4) continuum theory-based incident detection, missing data estimation, and shock wave propagation prediction. The first research activity is broad in scope and will provide a typological focus for ITS forecasting research and guidance for new course development and course enhancements to support the education and training of 21st century ITS practitioners and researchers. Specific educational activities will include (1) undergraduate course development and enhancement to increase student exposure to information technologies and infrastructure sustainability, (2) development of a new traffic flow theory course directly linked with ITS research activities, (3) involvement of undergraduates in ongoing ITS research activities through interdisciplinary research teams under graduate student leadership, and (4) active recruitment of students from traditionally underrepresented groups through various programs aimed at incoming students and graduate school candidates.These research and educational activities will be built and integrated around a new campus traffic operation center and ITS lab. The lab will provide direct access to system-wide traffic condition data and full motion surveillance video. This ready access to system-wide data will greatly enhance the research and graduate education efforts. Special emphasis will be placed on exposing undergraduates to ITS research and development through course projects and undergraduate participation in ITS research teams. The ITS lab will also serve as a showcase for student recruitment, including efforts to attract women and underrepresented minorities to civil engineering.

交通拥堵仍然是美国城市面临的最紧迫的问题之一。 智能交通系统 (ITS) 提供了可持续解决城市交通问题所需的系统视角。在 20 世纪的最后十年中，ITS 监视、检测和旅行者信息技术投资了数亿美元。在第一代智能交通系统中，利用大量遥感数据进行自动化、时间关键的管理和控制仍有很大的潜力尚未开发。下一代智能交通系统需要进行多尺度全系统预测和状态估计，以支持主动而非被动的交通系统管理。 该职业发展计划将为智能交通系统的全系统交通状况监测和状态估计提供综合研究和教育框架。 研究活动将包括：(1) 开发全系统 ITS 交通状况监测和预测框架，(2) 用于单变量预测的基于季节性 ARIMA 的卡尔曼滤波，(3) 将连续交通流理论应用于一步系统预测， (4)基于连续介质理论的事件检测、缺失数据估计和冲击波传播预测。 第一项研究活动范围广泛，将为 ITS 预测研究提供类型重点，并为新课程开发和课程增强提供指导，以支持 21 世纪 ITS 从业人员和研究人员的教育和培训。 具体的教育活动将包括 (1) 本科生课程开发和强化，以增加学生对信息技术和基础设施可持续性的接触，(2) 开发与智能交通系统研究活动直接相关的新交通流理论课程，(3) 本科生参与正在进行的项目通过研究生领导下的跨学科研究团队开展 ITS 研究活动，以及 (4) 通过针对新生和研究生院候选人的各种计划，积极从传统上代表性不足的群体中招募学生。这些研究和教育活动将围绕新校园进行和整合交通运营中心和ITS实验室。该实验室将提供对全系统交通状况数据和全动态监控视频的直接访问。这种对全系统数据的便捷访问将极大地加强研究和研究生教育工作。将特别强调通过课程项目和本科生参与 ITS 研究团队，让本科生接触 ITS 研究和开发。 ITS 实验室还将作为学生招募的展示场所，包括努力吸引女性和代表性不足的少数族裔进入土木工程领域。
