Major highway reconstruction can cause significant disruptions to existing travel patterns and economic activity. Reducing these impacts on travelers, shippers, businesses and residents requires that innovative and effective transportation management actions be developed and implemented. This paper reports the major findings and recommendations of a research study on managing transportation during highway, reconstruction. The primary objectives of the study were
The recommended process consists of five chronological phases, each composed of many tasks having related focuses within the overall process. Each task is designed to contribute to the common objective of seeing that an effective transportation management plan for mitigating travel impacts throughout the project corridor is successfully realized. This process was formulated on the basis of information collected on 25 highway reconstruction projects throughout the United States by way of site visits, direct meetings with project personnel, requests for documentation, and phone interviews. 相似文献

Serret-Frenet框架下欠驱动船的输出反馈路径跟踪鲁棒控制 总被引：1，自引：1，他引：0
研究欠驱动船舶在规定速度条件下的路径跟踪控制问题,提出一种基于终端滑模与Backsteping方法相结合的复合输出反馈控制策略.该控制策略利用Backsteping能够获得控制算法显式解的优点,构造出控制器算法的结构形式,然后设计一个基于观测器设计的逆动态终端滑模面,使得系统的估计状态跟踪误差能够在有限时间到达滑模面上,最终达到系统可镇定.最后,通过Lyapunov稳定性理论证明该复合控制策略的稳定性.利用实船数据进行数字仿真,结果表明该控制策略具有良好的跟踪性能. 相似文献
