Recently, Professor Qingyun Wang published a book titled”My Viewpoints on Transportation Development". It’s an important academic achievement worthy to pay attention to in the transportation field. This book was published by Chinese Science and Technique Press. The book had been re-printed three times in less than 3 months，which is not so common. Since his graduation in 1982，Professor Wang has been working on the transportation development planning and policy in the National Development and Reformation Committee (NDRC, formerly the National Planning Committee). In the last 20 years，the transportation in our country has been transformed from planning economy to market economy, he has witnessed and directly participated the activities of practicing the decision in the whole process. As the present director of the Department of Traffic and Transportation in NDRC，the visiting professor of Beijing Jiaotong University and Nankai University, Professor Qingyun Wang pays much attention to the combination of transportation theories and practices. He usually emphasizes the opinions from the academic professionals in transportation decision-making, and also takes apart in various academic activities in the field of transportation. In his new book, he discusses incisively on the special subjects of some key issues， which are related to the construction of comprehensive transportation system in socialism market economy in China based on his long-term experience in planning of comprehensive transportation in our country. These special subjects include eight aspects as below, Look at the transportation development problem with a new development view; Transportation and economy development; Transportation planning; Transportation market theory; The reformation of transportation systems; The development of comprehensive transportation system; Transportation and physical distribution; Sustainable transportation policy. His analyses to above special subjects have important affects on some actual work, such as studying current transportation system engineering management theories and practice problem, pushing comprehensive transportation ’the Eleven Five Plan’ in our country and so on. In order to let everybody understand the essential points of this book，the journal publishes here the first chapter of the book partly from ”My Viewpoints on Transportation Development" in two periodicals and hope all our readers may understand some important viewpoints from the paper.

Informationalization of the Olympic Transportation

WANG Jiang-yan,LI Peng-fei

2004, 4(4): 19-24 .

Abstract ( )

PDF (505KB) ( )

Since Beijing was awarded the hosting of the Olympic games in 2008, the City has been dedicated to planning and construciton the necessary facilities . To make the Beijing Olympic Games the best in the Olympic history, the Beijing government has devoted an unsurmounted amount of resources to achieve this goal. One of the ways to achieve this overall goal is to enhance the existing traffic system with higher mobility to and from the Olympic Green area (Olympic Center Area) during the games. Additionally, the inclusion of sustainable development to the traffic system enhancement is of great importance to Beijing Organizing Committee of Olympic Games (BOCOG).
To ensure the success of Olympic Games in 2008, it is urgently needed to set up a complete and scientific plan. In this article, the authors will give some suggestions based on their experiences in the last 2 Olympic Games, including drawing up the master strategy of the Olympic traffic, the Olympic traffic command center, Traffic operation plan and security strategy, emergency plan and pedestrain research.
At the same time, since the first appearance of ITS technology in the Olympic Games in Atlanta. ITS has been playing a more and more important role in giant sports events.The issue of ITS strategy of the Olympic Games shoude be concentrated on only how to satisfy the game-period traffic command, but also how to integrate these facilities with the other devices to serve.

Abstract ( )

PDF (517KB) ( )

The use of smartcards, as a means of accessing and paying for operators in the world public transit industry. The advantage of the smartcard technology have contributed to the obvious conveniences and benefits to both passengers and operator, such as faster boarding, lower survery costs, more sufficient information for planning and prevention of fraud, and better ability to expand integrated ticketing than conventional fare payment methods, such as cash and bus passes. This paper reviews some typical smartcard projects in the world and examines the general trends of smartcard applications in the future. Also this review will lead to the further studies on the smartcard applications in China and their comparisons with other countries’ so as to make suggestions for the development of smartcards in Chinese public transport.

The Study of Advanced Traffic Control and Management System on the Base of Cities in China

YANG Xiao-guang

2004, 4(4): 49-53 .

Abstract ( )

PDF (407KB) ( )

At present, our city’s traffic control system are always using some foreign developed system, like SCOOT, SCAT etc. , which are all developed on the base of vehicle-centered traffic condition. In fast, these systems don’t fit the complicated traffic condition in China, especially on the coordinate control of interrupted and uninterrupted traffic flow and bus priority control. So they can’t meet the demand of ITS development in China. This paper is the result of the project of “city traffic inspection and management system”, which is a subproject of national foundational study and planning. On the basis of the character of the city traffic in China, the auther put forward a real-time adaptive traffic control system which can fit the traffic condition in China cities very well.

A Theoretical Analysis to Urban Transport Operations
on Single Railway Lines

WANG Hai-chao

2004, 4(4): 60-63 .

Abstract ( )

PDF (308KB) ( )

Due to the smaller transit capacity,it is considered that the monglines railways are not fit to offer urban transport service for passenger transport in urban areas. This paper analyzes the variaties of transit capacity on monglines railways with more stations and shorting of stations distances. It also discusses the transportation organizations on the mongline sections mixed with freight trains and MU trains. Taking some real railway for example，the paper concludes that it is possible for the mongline railways to provide passenger transport service for urban areas after reforming tracks and shortering stations distances.

Maximum Design Speed for Urban Railways of China

SU Mei, LI Jian-xin

2004, 4(4): 64-67 .

Abstract ( )

PDF (454KB) ( )

This paper analyzes the main factors related to the maximum design speed of urban railways and studies the advantages and disadvantages of increasing maximum design speed. Based on the practical line data, the paper calculates the operational performance, including traveling speed, energy consumption and time saving, of urban rail systems under different maximum design speeds of 80km/h, 100km/h and 120km/h by the TraMCES simulator developed by the Key Laboratory of Traffic and Transport Systems of the Ministry of Railways of China. The simulation results for an urban rail line of 37km long with average distance between station of 2.64km show that the average travelling time under the maximum design speed of 100km/h may decrease by 12.1% but its corresponding energy consumption will increase by 22.7% while comparing with that of 80km/h.
