| With the rapid development of modern society and economy, the improvement ofpeople’s living standard, the number of motor vehicles and private cars showed rapid growthtrend, it will cause the city traffic congestion, will be a major challenge for modern city traffic.The subway is one of the effective ways to alleviate the pressure of the city. How to make themetro transportation has the advantages of high efficiency, safety, comfortable, on time willbe an important goal of modern city orbit traffic system research. The time table system is avery important part in city track traffic, city rail transit plans often need to adjust according tothe characteristics of passenger flow.This thesis consists of two parts, the first part is combined with the already openedLanzhou subway line as the background, combined with the planning and layout of LanzhouCity, the traffic situation and passenger flow characteristics of Lanzhou subway along the line,and according to the travel of city residents, design a suitable for Lanzhou metro lineoperation time table system. Firstly, concepts, briefly introduces the schedule, and then to themodular design of the schedule system, demonstrating the structured management andvisualization system for time to achieve. Functional requirements of the system through theschedule, the detailed design of each module function, including the time table test module,schedule automatic generation module, time table editor module, finally simulate theoperation schedule system. On schedule the implementation process, first of all to eachinterval corresponds to each line of the input to the number of trains, train station, attribute,interval of abstract modeling, to establish the corresponding data dialog box, and to store thedata saved to the database, the corresponding table, call for back production schedules. Thesecond part is the main content of the early generation of the reference timetable and theLanzhou metro line one relevant data to generate schedule optimization, list goals andstrategies, and then use genetic algorithm to optimize each time, to find the optimal interval,so as to the subway, punctual, efficient and reliable operation.Urban rail train schedule system using a good Windows interface style, ADO.NET C/Sarchitecture, C#, Sqlserver2008and modern way of accessing database program design,through the use of these technologies to enhance the two development schedule system.Design of a suitable for modern city rail transit time table system from the operation andpracticality, can improve the city rail transit schedules work efficiency of the system, has thebroad application prospect. |
