Study On The Evaluating Index System For Passenger Station Designs Of Passenger Dedicated Lines

With the development of computer technology, superiority coming from computer technology is applied by more and more research in the related fields of railway. One is the simulation using of railway station. Especially in this period, a large-scale construction of PDL is on the way in our country. Design of stations for PDL needs higher requirements than the stations for the low-speed-level railway lines in which passenger trains and freight trains are running together. After finishing the initial yard design of station, its simulation using by computer technology is becoming an effective method to investigate the property of the design. However, now, a systematic, comprehensive index system which is used for evaluating the design’s simulation results, is lacked domestic and overseas.Based on the background above, this paper makes a study on the evaluating index for the station’s design. The study does a further research of deploying revolving equipment in passenger stations of PDL. It includes the following aspects:1. The technical standard of the station yard design and railway operation processes in station are expounded. At the same time, this paper dose clear and definite the study conditions. It expounds the basic data and major parameters in station yard design. Related parameters and data are analyzed and disposed as parameters for evaluating.2. Based on the initial design of station yard, the static performance of the design is researched, mainly including the overall arrangement for yard, analysis of the influence between the length of throat and the trains following-running blank, analysis of trains station-organization time, evaluation of the properties for routes, evaluation of the static capacity for the throat, evaluation of the number and available lengths for arrival-departure lines. After that, the static index system is established.3. An explicit description is given for the items of the simulation, including the contents and purpose, the developing thinking and features of the simulating system, and the specific process of the simulation.4. Based on the simulation of station yard design, the dynamical adaptability of the design which is brought up under the simulation of itself is researched, mainly including that the overall adaptability (trains work finished), checking for the trains following-running blank by simulation, evaluating the adaptability of the equipment and routes arranged, evaluating the capacity adaptability of all the arrival-departure yards, turn-back yards, lines used for EMU. Before that, the influence of capacity brought by the organizing forms of turn-back yards and lines used for EMU is deeply researched. At the end, the dynamical index system is established.By analyzing the station design itself and its simulation deeply, a complete, systematic evaluating index system is established. This system can provide an effective, precise, qualitative and quantitative evaluation for the design of terminal stations of PDL, with giving targeted advices which can guide the improvement of design. Besides, this index system can provide some help to improve the simulating algorithm and software, then a benign cycle which is that "simulation exports indexes,&indexes guide the simulation." can be set up.
