交通

As a fast-developing and modernized metropolis,Xi'an also faces the great pressure of traffic-jam which the traditional means of improvement can no longer alleviate.People begin to put advanced information technology,statistical connection technology,electronic control technology,computer-processing technology into ground traffic controlling system comprehensively in order to establish a large scale system named Intelligently Transportation Systems which would run accurately and effectively.

作为飞速发展的现代化大都市，西安同样面临着交通堵塞的巨大压力，在传统的改造方式已不能再有效的缓解这种交通压力时，人们开始把先进的信息技术、数据通信技术、电子控制技术、计算机处理技术有效的综合运用于地面交通管理体系，从而建立起一种大范围、全方位发挥作用的、实时、准确、高效的交通运输管理系统——智能运输系统。

The ARIMA model has been applied to evaluate and predict the time series of macroscopic traffic volume.Complexity and prediction errors of 5 actual time series have been calculated.Based on the comparison of the calculated results,it is assumed that complexity is negatively correlated with predictability in macroscopic transportation system. complexity,prediction,transportation,Lempel-Ziv algorithm

针对这个问题，本文对宏观交通运输系统进行复杂性测度和时间序列模型估计，进而研究系统复杂度和可预测性之间的关系。1宏观交通运输系统的复杂性测度从上世纪末开始，关于交通运输系统非线性关系判据的研究方兴未艾，而对于如何实现交通运输系统可比化的复

In a transportation network supported by the Advanced Traveler Information Systems,the drivers equipped with ATIS are directed by a control center to select their routes so as to minimize the total network travel time,while the unequipped ones make the route choice decisions on the base of minimizing their individual travel times.

考虑一个被路径诱导系统支持的交通网络，装有ATIS的出行者接受交通中心的指挥、按照系统最优的原则选择路径，没有该装置的出行者根据个人成本最小的原则择路，建立了刻画这种混合交通行为的变分不等式模型，推导了混合交通行为网络的效率损失上界，并以多项式路段成本函数为例给出了一些上界的特殊值。

Setting out from the range of research of the road and waterage, synthesizing the definition of the original road traffic accident and aquatic traffic accident, this topic first puts forward a new concept of traffic safety management suitable for the topic, and gives full comprehends and analyses to the intensions and characteristics of the traffic safety long acting management.

本课题首先从道路和水路运输的研究范围出发，综合原有的道路交通事故和水上交通事故的定义，提出了新的、适合于本课题研究内容的交通安全管理的概念并进行阐述，并对交通安全长效管理的内涵和特性进行了充分的理解和剖析。

The power spectrums of the time serials of traffic flow are illustratecd.Through the analysis of the power spectrum of the headway,it is clear that there are variations of noise and wide apices.

有关交通流混沌现象的研究大多是以跟驰模型产生交通流，并对所产生的交通流施加一定的干扰，来研究这种理论交通流的混沌现象、证明混沌的存在。

Secondly, the model of the passengers forecast were studied. The corridor analytic method was proposed in the metropolis rail transit passenger flow forecast application, The traffic district for passengers forecast was raised, which is centered on the hub, circled with the radius of attrahent scope .The forecast model applying toestimating the volume of collecting and dispersing passenger generation and transfer passenger distribution are raised, the example proved that the models are reliability and practicable.Thirdly, the plan theories of metropolitan rail transit were studied.

研究了都市圈城际轨道交通客流预测的方法；提出了走廊分析法在都市圈城际轨道交通客流预测中的应用，提出了以枢纽节点为中心、以吸引范围为半径的圆形范围为客流预测的虚拟交通小区的划分方法；并依此在确定吸引范围的基础上，提出了基于效用矩阵的都市圈轨道交通客流预测模型，实例分析证明该方法具有较强的实用性和可靠性。

To ensure realization of development planning of urban rail traffic in Tianjin and successful implementation of metro construction projects, establish a public communications network backboned by rail traffic, provide citizens with convenient, fast, cost-effective and secure communications service, it is necessary and urgent to study countermeasures for metro financing in Tianjin for the time being.

为保证天津市城市轨道交通发展规划的实现和地铁建设项目的顺利实施，构筑以轨道交通为骨干的公共交通体系，为市民提供方便、快捷、经济、安全的交通服务，在现阶段，对天津地铁融资对策进行研究是必要的和紧迫的。

By using classific and compositive methods,it provided the ways to realize urban public traffic policies sustainment.Aim at the characteristics of urban group traffic,it brought forward some advice on how to develop urban group public traffic.

基于一些实例，分析和研究了不同需求下的公共交通发展定位；通过分类集成，提出了实现政策支持的条件下公共交通发展的方法；针对城市群众交通的特点，对公共交通的发展提出了规划和管理的建议。

The system is suggested to approach the problem by means of geographical information system component software. Because the GIS was integerated in the whole system , some of the traffic facilities will be displayed in the concreate map and become more easy to control and manage , in this way the traffic will also become more free,secure and efficient.

将GIS技术应用到智能交通系统之中，实现了交通设备可视化的操作、监控以及管理，实现了道路最短路径算法，辅助城市交通管理部门的工作，保证交通要道的安全、畅通和快速。

Have analysed modern city traffic controlling and managing the problem current situation, important problem operating principle , the automation realizing traffic light having set forth traffic light navar with a view of unobstructed reality of city and countryside are commanded to be that urban traffic control automates.

分析了现代城市交通控制与管理问题的现状，结合城乡交通的实际情况阐述了交通灯控制系统的工作原理，实现红绿灯的自动指挥是城市交通管理自动化的重要课题。

Life. But the intrinsic way of the Internet by wire confines accessing and using of the network information.

然而，Internet固有的有线连接方式大大限制了人们对网络信息的访问和使用。

I have a strong persuasion that this is true .

我坚信这是正确的。
