The transportation organization is indicating the synthetical organization administration model about traffic capacity and transportation resources . transportation organization mainly research on the method and efficiency about the transportation resources how to be used , that is the transportation resources including the different transportation tools , stations , storehouses , enterprises , human resources and technology , capital and information etc how to be related together in the course of satisfying the transportation requirement 运输组织就是指对运输对象及运力以及相关运输资源的综合组织管理模式，运输组织主要研究运输资源整体上利用的方式和效率，即运输资源包括不同的运输工具、站场、仓库、相关企业、相关人力资源和期间的技术、资金、信息等在满足运输需求的过程中，不同环节和不同方面之间的联系方式，这些资源为满足运输需求而进行整合的过程就是组织化。
Then the research discusses and analyzes each environmental factor of environmental pollution and the relation between them and the amount of automobiles ; refers the concepts of environmental traffic capacity and traffic environmental capacity and finds the relation and difference between each factor and traffic capacity ; establishes compute model for environmental traffic capacity and logical relation between it and traffic environmental capacity 本研究就此讨论分析了环境污染中与机动车有关的各污染因子及其与机动车数量的关系，提出了环境交通容量和交通环境容量的概念及与交通容量的区别和关系，并通过结合现有的研究成果建立了环境交通容量的计算模型，并确定了与交通环境容量的逻辑关系。
Finally , the research finds the largest amount of automobiles permitted by environment through analyzing situation of environment , influence of automobiles on environment and potentiality of development of automobiles in quantity , have calculated traffic capacity and traffic environmental capacity for xi ' an in 2005 , 2010 year 定量分析了西安市环境状况和机动车对环境的影响状况和发展潜力，确定了西安机动车的最大交通环境保有量，并预测了西安市2005 、 2010年的交通容量、环境交通容量。
( 2 ) develop an urban microscopic traffic simulation system , which involves vehicle generation model , network model , traffic regulation model , signal control model , vehicle action model , route choice model and intersection turning model . ( 3 ) realize and research the method that signal cycle and phases are assigned by the traffic need . when vehicles od is known , this method can be used to decide the maximum traffic capacity of signal - controlled intersection and the evaluation reference of current control method 模型中充分考虑了邻道车辆对驾驶行为的影响及驾驶员的反应延迟，使模型更符合真实情况； ( 2 )开发了城市微观交通仿真系统：该系统包括车辆产生模型、路网模型、交通规则模型、信号灯控制模型、车辆行为模型、路径选择模型、路口转向描述模型； ( 3 )在仿真应用中实现并研究了信号灯周期及其相位按交通需求动态分配的方案，提出该项仿真可用于确定在已知od下，信号灯控制路口的最大通行能力，并可作为现有控制方案的评估依据。
Similar to asama protocol , qasama protocol applies ppo and go algorithm , but qasama protocol also considers the requirements of packet delay , packet drop rate , bit error rate ( ber ) , traffic capacity and channel utilization , and integrates these requirements into the slot allocation procedure 在qasama协议中，综合考虑了分组时延，分组丢弃率，误码率，业务容量以及信道利用率方面的要求，并将这些要求与多波束智能天线的特点及自适应时隙分配过程有机地结合起来。
According to the practical observation , a math method to calculate the traffic capacity is discussed . a grey incidence analysis model is set up to analyze incidence degree between environment factors and the vessel accidents in port in order to find out the instinct reason in chapter 4 . that the visibility and the vessel traffic are the most two important factors is concluded 第四章利用灰色系统理论对港口船舶交通事故主致因进行灰色关联分析，并且对计算模型的改进提出了作者的见解，用灰色综合关联度的数学模型对沿海六个港口环境因素八个指标与船舶交通事故的关联度进行了定量的计算；指出能见度不良和港口船舶交通量是港口环境中导致船舶交通事故的最主要影响因素。
Therefore , the most insistent and practical research subject is aimed to improve the traffic operation quality for solving the traffic problem at the intersections in whole urban road network by means of adapting the efficient traffic management measures , reducing the traffic conflict , increasing the traffic capacity and improving the traffic safety and so on 因此研究解决平面交叉口的交通问题，采取有效的交通管理措施，减少交叉口的交通冲突，提高交叉口的通行能力和交通安全性，从而提高整个城市道路网的交通运行质量是目前最为迫切、最为实际的一项研究课题。
