China Railway Express’Success and Its Revelation for Railway Reform RONG Chao-he, DONG Yan-hua 2004, 4(1): 3-11 .  Abstract ( )   PDF (1050KB) ( )   Through analyzing the success of China Railway Express (CRE)in exploiting parcel delivery service network, this paper displays the main problems existing in Chinese railway system and points out directions for its reform. According to the authors CRE formed a grid network rapidly with very low cost，realized the complete control of the whole express service process through property rights adjustment，and became the real transport enterprise full of vigor in the state owned railway system. The authors believe it is necessary for reorganizing the railway industry to establish transport enterprises capable to compete in the market freely and to take all their responsibilities，renovate the transport conception，energetically accelerate the extra value-added operation development while further expanding and perfecting the basic operations，and change the industry from the past system in which operators have been serviced by themselves to a new customercentered or market oriented one.

Intelligent Economic Forecast Method Based On Genetic Algorithm LI Xue-w ei,MANG Jiang 2004, 4(1): 18-22 .  Abstract ( )   PDF (432KB) ( )   This paper gives some discussions on genetic algorithm that are applied to the problem of the model choice of intelligent economic forecast. First，the model in the model base is coded to the population of the genetic operations. Second, new models or combinations of them are created by cross and mutation operation. Furthermore，the generated models will be self一adaptive and selflearning. They can be scored by some evaluations that are regarded as the individual fitness to be the choice operation of the genetic algorithm. Finally, a better model of forecast is produced to forecast the data. As an example，the forecast analysis of the passenger transport of China is stated in the end of the paper.

A Review of the Development and Current Situation on Bus Priority at Intersections JI Yan-jie,DENG Wei 2004, 4(1): 30-34 .  Abstract ( )   PDF (462KB) ( )   Bus priority transit in urban is an important treatment for the development of bus priority. Bus priority at intersections can reduce bus delay, increase their speed，just to availably ensure the bus arriving on time and enhance the level of bus reserve. This measure will be of great important to promote the development of public traffic，relax traffic pressure of urban and assure the city to develop persistently. Based on the review of bus priority at intersections，the problems and insufficiency of bus priority at intersections research in China at present are pointed out. Finally, the developing trend of bus priority research is presented. References | Related Articles | Metrics
