An Important form to Realize the Acceleration of Railroad Development——joint-stock System LI Wen-yao 2003, 3(3): 14-21 .  Abstract ( )   PDF (621KB) ( )   By employing historical, comparative and logical methods and briefing the course of railroad development at home and abroad, the article argues that the guiding principle on the reform of state-owned enterprises addressed by Comrade Jiang Zemin is correct through. The article points out: after the ups and downs in the global railroad community in the past century, joint-stock system, besides maintaining its original function in raising money, demonstrates vitality and energy in optimizing the allocation of resources among railroad enterprises, promoting economic returns and strengthening competitive power of railroad enterprises. Although joint-stock system didn’t yield perfect fruits in Old China’s railroad community, it still stands to be good to attempt to explore the way for multi-channel investment. After analyzing the new situations and characteristics occurred in current Chinese economic and social development，the article points out: basic national conditions, geographic characters in different regions, the imbalance in economic development between regions, the difference in the adjustment of economic structures and the severity in the structures of energy and consumption decide that railroads in different regions are faced with different challenges and opportunities, that different regions have different subjects of passenger and freight, that railroad would still play a key role in the process of China’s industrialization and urbanization in 21th century, that it is complicated, urgent and stable to explore the way to reform in the railroad community that conforms to our national conditions, that the variety of railroad performing mechanisms in different regions，in different forms and by different methods. To carry out joint-stock system meets the requirement of building the system of modern enterprise, which is a realistic and effective way to speed up the development of Chinese railroad in the new century and could produce results in many aspects.

A Stochastic User Equilibrium Model under ATIS and Its Evolutionary Implementation XIONG Yi, HUANG Hai-jun, LI Zhi-chun 2003, 3(3): 44-48 .  Abstract ( )   PDF (286KB) ( )   In a road network served by advanced traveler information system (ATIS), commuters will select their routes and departure times through comprehensively utilizing previous knowledge on traffic condition and current information from ATIS. In this paper, we divide all commuters into two types, namely optimism and pessimism with different attitudes toward ATIS service, and study their travel time determination. Then we formulate an expected perceived travel time function that will be used as personal knowledge in the next round route choice, and investigate its properties. Finally, we propose an equivalent mathematical programming that for each time period realizes the logit-based stochastic user equilibrium route choice with expected perceived travel times.

A Research on Traffic Accident of Over-Speeding Vehicle on Expressway JIANG Hua-ping, XU Hong-guo, LI Hao,LIX iang-gui 2003, 3(3): 49-51 .  Abstract ( )   PDF (193KB) ( )   Because of rapid development of expressway and vehicle technology, vehicle fleetness transportation brings prodigious social benefit and economic benefit. But unsafe factors of vehicle over-speeding on expressway should not be ignored, daily occurrence of traffic accidents make huge harm for human life and property. This paper presents impacts of over-speeding to driver driving patterns, vehicle performance, and kickbacks caused by over-speeding. Driver should select moderate speed based on various vehicles to ensure traffic safety and improving transit capability. References | Related Articles | Metrics

Congestion Pricing Theory Development and Appliance in China WANG Ban, HU Yun-quan,XU Ya-guo 2003, 3(3): 52-57 .  Abstract ( )   PDF (442KB) ( )   Congestion pricing, an important element of TDM (Transportation Demand Management), has been key content of traffic economics. This paper reviews the history and late studies of congestion pricing theory, points out the research directions, analyzes the application effects in practice, puts forward advices of pushing congestion pricing policy in China. The practice of congestion pricing indicates that the policy is very effective in controlling traffic flow, and the key to make congestion pricing more feasible is how to gain public support, which will be the basic and difficulty of pushing the policy in large and medium cities of China.
