The construction of expressway was started from mid - 1980s in china , and shanghai - jiaxing expressway open to traffic in 1988 signalized the zero outbreak in the area of expressway construction of china ' s mainland 我国高速公路建设起步于20世纪80年代中叶， 1988年底上海至嘉定高速公路的建成通车，实现了我国大陆高速公路零的突破。
Several techniques are discussed , when establishing this system . the expert system of signalized intersection initiates a new research field of urban road traffic management . thirdly , the sub - system of signal timing is presented 信号交叉口优化专家系统开创了道路交通管理研究的新领域，为充分发挥交叉口的时、空资源提供了新的理论框架。
Most of works we have done are only drawing lessons from foreign advanced experiences . based on the situation of optimal design of signalized intersection , a system of optimal design of signalized intersection was put forth 对于任何一个城市，加强道路基础设施建设、改善城市快速干道系统是必要的，但做好平面交叉路口的规划、设计、治理和管理工作无疑具有极其重要的意义。
In chapter 5 , the methodologies of calibrating the road weight measured by travel time based on road impedance function model and signalized intersection delay model are proposed , and are realized and verified using a large amount of field data 论文第五章提出了基于路阻函数模型和信号交叉口延误模型，标定以出行时间度量的道路权重的方法体系，并利用实测数据加以实现和检验。
On such occasions the return of the adjuster signalizes the awakening of the human soul , and this is the repersonalization of the dead just as literally as when the en masse roll is called at the end of a dispensation on the evolutionary worlds 在此类调停者发信号唤醒人类灵魂返回的情形下，而这就是死亡的重新人格化正如文字上的意思如同当一个大量的滚动就是所谓的在进化的世界里处于分配的尽头时候。
Vehicle delay at signalized intersections is the important measure of running efficiency and server quality . it reflects not only the drivers discomfort , restrain , oil consume , time lose , but also reflects the logical of signal control and design 信号交叉口延误是评价信号交叉口的运行效率和服务水平的重要度量，它不仅反映了司机不舒适和受阻程度以及油耗和行驶时间损失，还反映了信号控制、设计的合理性。
Several popular and classical traffic control systems , such as transyt , scats and scoot are analyzed . moreover , some achievements in research of signalized intersection are earned in china . however , the start of studying signalized intersection is too late 在我国，由于近年机动车保有量迅速增加、交通基础设施建设滞后以及管理措施不够完善等原因，致使平面交叉路口的交通拥堵日趋严重，进而影响到城市路网通行能力的发挥。
In addition , in the paper great attention is paid on the advantages and disadvantages of the waiting area for left - turn vehicles at signalized intersections , and the capacity and application principle of advance right - turn vehicle flows , which are put in practice but lack of theory supports 第四章是针对左转待转区在实际使用中存在的误区,对左转待转区的设置利弊进行了详细的分析和研究,得出了左弯待转区的优缺点以及在工程使用中应该注意的事项。
Because of the different function of roads and the difference of region , the form of intersections and connections between them is different with each other . at present , the types of nodes adopted in china and abroad include uncontrolled intersections , all - way stop - controlled intersections , two - way stop - controlled intersections , signalized intersections , roundabouts , grade - separated junctions and their combinations . each type of nodes has different characteristics and adapts to different function demands 城市道路是以网络形态分布于城市区域内的地面交通设施,由于道路的功用不同以及地域的差异,各道路间的交叉和连接方式各不相同,目前国内外所采用的节点形式有无控制平交节点、全停牌控制平交节点、二路停牌控制平交节点、信号灯控制平交节点、平面环行节点、立体交叉节点以及它们的组合形式,各种节点具有各自的特性,适合于不同的功能需求。
Dvb / mpeg - 2 transport stream multiplexer / demultiplex takes an important role in digital video broadcasting system . it can combine several transport streams from source encoder into a single transport stream to transport channel , or demultiplex trasnsport stream into one program sorce to source decoder . its performance has a great influence on the program transmission ability of hdtv system and the decoding quality of decoder in hdtv receiver . mpeg - 2 system multiplexer signalized video , audio , host data and so on to fixed length packet type for making transport stream Dvb mpeg - 2传送流复用解复用是数字电视广播系统中的重要组成部分之一，它将从信源编码器输出的多路节目源复用成一路传输流送入传输信道，或者从信道中包含多路节目源的一路传输流中解复用出一路节目送到解码器解码。
