从京沪高速公路（临沂段）路面大修中谈交通管制

高速公路大、中修过程中大多采用边通车,边维修的方法,因此,大、中修过程中的交通管制就显得尤为重要。以京沪高速公路路面大修(临沂段)施工过程中的交通管制为例,通过对减速距离等参数的分析,得出了交通管制与减速距离的关系,并对京沪高速公路(临沂段)大修中利用中央分隔带紧急开口绕行时交通诱导设施布置方案的安全性进行了分析与探讨。     

Multiphysic modelling of railway vehicles equipped with pneumatic suspensions

This article presents a multidisciplinary approach of railway pneumatic suspension modelling: both multibody and pneumatic aspects are taken into account. The work aims at obtaining a realistic model of the secondary suspension and coupling it with a multibody model of a train. Various components of the pneumatic circuit such as bellows, tanks, pipes and valves are taken into account. The article focuses on the bellow-pipe-tank subsystem for which several modelling approaches are presented and compared. Differences between differential and algebraic models are highlighted, and an application-dependent choice between them is suggested. A complete model of the pneumatic circuit is then obtained and coupled with a multibody model of the train. As a result, the behaviour of a suburban train equipped with a pneumatic secondary suspension is analysed, in particular undesired oscillating motions which affect the comfort. Topological modifications and improvements of the suspension are also investigated and discussed.

Japanese perspective of driver information systems

A perspective view of of Japanese R&D activities of Driver Information Systems is given from the standpoint of developing joint projects by public and private sectors. First, a brief history of the R&D activities is illustrated from above mentioned standpoint. Then, two major projects, AMTICS and RACS, and the social backgrounds of these projects are explained. In order to give a clear idea of both projects some technical details are treated.Based on the history and the present status of the developments, the basic design conceptions of Japanese Driver Information Systems are explained and several factors or reasons which have influenced to the design conception are discussed. Then, the promoting systems of the R&D activities are generally explained and present status of the projects and future problems in developing more advanced systems are also handled. A brief discussion on the establishment of international standard is also mentioned as a final comment.     

大型购物中心诱增交通量预测方法研究

近年来，随着人们生活水平的提高和消费观念的改变，shopping mall正在中国越来越热。shopping mall由于体量庞大，它的建设无疑会对城市道路交通体系产生较大的影响。本文在对北京mall交通影响分析实践的基础上，根据购物(休闲娱乐)出行需求的特点，提出了大型购物中心诱增交通量预测的思路，并重点阐述了商圈分析法和非集计模型在诱增交通量预测中的应用，取得了较好的效果。     

对中国未来10年道路交通安全状况分析与初步预测

笔者从中国现代道路交通系统的发展现状与道路交通安全状况出发，以过去10多年中国汽车、摩托车保有量的发展轨迹为基础，对中国未来一定时期（2004～2015年）机动车保有量的发展变化及政府采取不同管理对策条件下的道路交通安全状况的发展水平进行了预测。结果表明：政府管理对策对道路交通安全状况变化具有决定性影响。     

A scenario on the evolving road service informatics in Europe

Road Transport Informatics is being developed to improve road transport. Telecommunication links will connect microcomputers in vehicles with roadside beacons and traffic control centers. Drivers can get better information and guidance en route. If these functions are charged as services rather than sold as products, a better traffic can be obtained. This can improve traffic safety, efficiency and the environment.     

和谐交通的伦理构建:系统、结构、层次

构建"和谐交通"是系统性的价值目标,需要以和谐伦理为导向,从宏观上审视现代交通关系的结构及其特征,研究交通主体之间、交通客体之间、交通主客体之间的基本关系及其状态,通过一系列调整优化,使之不断地从冲突走向和谐。
