【摘要】：智能交通系统(Intelligent Transportation System，，简称ITS)是未来交通系统的发展方向。它是将先进的信息、数据通讯、电子传感、自动控制及计算机等技术有效地集成，运用于整个地面交通管理，并建立一种在大范围内、全方位发挥作用的，实时、准确、高效的综合交通管理系统。ITS可以有效地利用现有交通设施、保证交通安全、对城市交通、治安管理进行有效管控、以满足人们出行需求和日益增长的各类综合业务需求。因而，对系统的成果进行深入的了解和客观的评价是十分必要的。本文遵循信息管理系统的设计开发应相辅相成的原理，提出A市智能交通系统的综合评价的原则、方法，设计了评价的流程。首先，评价体系的构建选择了层次分析法，确定A市智能交通系统的多个评价指标，给出每个指标具体的量化方法、合理数值的范围并计算确定了每个指标的权重。其次，使用邓聚龙教授提出的灰色聚类法，对A市智能交通系统进行完善的综合评价，得出目前A市智能交通系统建设成果的等级水平，在此基础上提供合理建议、科学参考。然后，在基于评价结果的基础上，本论文通过采用灰色关联法对后期建设的子系统备选方案进行对比、排序，然后得出比较贴近实际的、理想的方案。同时，也通过本论文，希望能建立中小城市智能交通系统的评价体系,能够为交通决策者提供合理建议，为公共交通决策者提供更为科学的参考。通过综合评价，判断得出目前A市智能交通系统交通硬件水平属于B级，安全效益水平属于C级，公共交通支持水平只有D级，而科学组织管理水平更是最落后的E级。综合4个一级评价指标的因素，得到了A市智能交通系统整体水平属于D级的结果，整体等级不高，属于中下水平，可以看到造成这一结果的主要原因在该系统所达到的、贡献的安全效益水平一般、智能交通系统对当地的公共交通支持水平几乎没有得到开发、而对规划前期、建设完成后运营贡献很大的科学组织管理水平还有很大的提升空间。基于该评价，能够为交通决策者提供合理建议，为公共交通决策者提供更为科学的参考。
[Abstract]:Intelligent Transportation system (ITSs) is the development direction of future transportation system. It is an effective integration of advanced information, data communication, electronic sensing, automatic control and computer technology, which is applied to the whole ground traffic management, and establishes a kind of real-time and accurate system that can function in a wide range and in all directions. The efficient integrated traffic management system (its) can effectively utilize the existing traffic facilities, ensure traffic safety, and effectively control urban traffic and public security management to meet the travel needs of people and the increasing needs of all kinds of integrated business. Therefore, it is very necessary to have a thorough understanding and objective evaluation of the results of the system. In accordance with the principle that the design and development of the information management system should complement each other, this paper puts forward the principles and methods of comprehensive evaluation of the intelligent transportation system in A city. The evaluation process is designed. Firstly, the AHP method is selected to construct the evaluation system, and several evaluation indexes of Intelligent Transportation system in A city are determined. The specific quantitative method of each index is given, the range of reasonable values is calculated and the weight of each index is calculated. Secondly, using the grey clustering method put forward by Professor Deng Julong, the comprehensive evaluation of the intelligent transportation system in A city is carried out, and the grade level of the construction achievement of the intelligent transportation system in A city is obtained. On the basis of this, reasonable suggestions and scientific references are provided. Then, on the basis of the evaluation results, this paper compares and sorts the alternative schemes of subsystem construction in the later stage by using the grey correlation method, and then obtains the ideal scheme which is close to the actual situation. At the same time, through this paper, it is hoped that the evaluation system of intelligent transportation system in small and medium-sized cities can be established, which can provide reasonable advice for traffic decision makers and more scientific reference for public transport decision makers. It is concluded that the level of traffic hardware belongs to class B, the level of safety benefit belongs to level C, the level of public transportation support is only level D, and the level of scientific organization and management is the most backward level of E. By synthesizing the factors of four first-level evaluation indexes, the result that the overall level of intelligent transportation system in A city belongs to D level is obtained. The overall level is not high and belongs to the middle and lower level. We can see that the main reason for this result is achieved by the system. The level of safety benefit is general, and the support level of intelligent transportation system to the local public transportation has hardly been developed, but the scientific organization and management level, which contributes a lot to the early planning and operation after the completion of the construction, still has a lot of room for improvement. Based on the evaluation, it can provide reasonable advice for traffic decision makers and more scientific reference for public transport decision makers.
