| 摘要： | This study presents an Integrated Traffic Information and Simulation System (ITIS), including a detailed description of its principal components and their interrelations, the main functions embedded in each technical module, and key algorithms employed to verify users needs and to perform the required estimation. The proposed ITIS system offers an effective tool for MSHA engineer/planners to take full advantage of information available from on-line detectors, archive data, and simulation results for estimating travel times during non-recurrent and recurrent congestion patterns. With those embedded functions and customized interfaces, the ITIS system can also be used for work zone planning and operational analysis, and for assessment of various traffic control strategies. The developed ITIS with its extensive information can also serve as an intelligent database system that can help potential users identify the data needs based on the requested applications, and perform the best estimation with available data. |
