    摘要:

    傳統的短時(shí)交通客流智能協(xié)調控制系統對于系統初始收集數據的處理效果較差,對于系統需求不夠明確,因此操作時(shí)間過(guò)長(cháng),系統工作效率低。為了解決上述問(wèn)題,提出基于GIS的短時(shí)交通客流智能協(xié)調控制系統。系統設計分為系統硬件設計與系統應用程序設計兩個(gè)方面,在整合系統硬件元件數據信息的基礎上完善系統硬件操作,提升系統數據處理能力,將硬件操作劃分為三個(gè)不同方面的模塊設計,縮減不必要的操作浪費,提升整體操作效率。在應用程序設計中集合相應的數據處理算法,研究GIS收集的內部信息,實(shí)現對短時(shí)交通客流智能協(xié)調控制系統的整體設計。實(shí)驗結果表明,基于GIS的短時(shí)交通客流智能協(xié)調控制系統設計能夠在較高程度上調整系統操作結構,優(yōu)化內部協(xié)調控制性能,具有高調配性。在客流量為60輛汽車(chē)時(shí),其操作時(shí)間為20s,控制有效率平均值為83%,滿(mǎn)足系統需求,具備更為廣闊的發(fā)展前景。

    Abstract:

    The traditional short-term traffic passenger flow intelligent coordinated control system has a poor processing effect on the initial data collection of the system and is not clear about the system requirements, so the operation time is too long and the system work efficiency is low. In order to solve the above problems, a short-term intelligent passenger flow coordinated control system based on GIS is proposed. System design is divided into two aspects: system hardware design and system application program design. Based on the integration of system hardware component data information, the system hardware operation is improved, the system data processing capability is improved, and the hardware operation is divided into three different aspects of module design. Reduce unnecessary operation waste and improve overall operation efficiency. In the application program design, the corresponding data processing algorithms are collected, the internal information collected by GIS is studied, and the overall design of the intelligent coordination control system for short-term traffic passenger flow is realized. The experimental results show that the design of GIS-based short-term traffic passenger flow intelligent coordinated control system design can adjust the system operation structure to a high degree, optimize the internal coordinated control performance, and have high deployment. When the passenger flow is 60 vehicles, the operation time is 20s, and the average value of the control efficiency is 83%, which meets the needs of the system and has a broader development prospect.
