Study On Bus Adjustments Related Shijiazhuang Metro Line 1 Optimization

With the development of era, the subway is more and more important in the position in public transport. But at the same time, as the development of the early bus, and the contradiction of the subway, the increasingly fierce competition, cause serious waste of resources. Only the advantage of flexible bus, wide coverage and subway combined the advantages of rapid, on time, comfortable, in order to promote harmonious and healthy development of public transportation system, form a win-win situation. Shijiazhuang subway construction began in September 2012, a total investment of 42.19 billion yuan. Shijiazhuang "small squares, big radiation" subway network layout is composed of 6 subway lines, line network is the total length of 241.7 km, total of site 242, which may change to the site of 29.Shijiazhuang per square kilometers of subway line network density is core area of 1.09 km,city center, 0.42 km. That year until June of 2017.This paper examines the correlation of shijiazhuang metro line 1 bus lines, shijiazhuang based on the actual characteristics, determine the scope along the metro lines 1 km on both sides of the service scope for subway, the subway lines can be divided into three parts in detail, this paper expounds the position of site, site design and the road on both sides of the environment, on the basis of attracting scope of each site, determine the bus lines associated with line 1 and article 115, calculated the repetitive site number and section of distances,theory-oriented and analyzes the present existing problems and reasons.This article from the passenger travel time, travel time, satisfaction, the respect such as travel factor has carried on the questionnaire survey, related to the location of the bus lines and subway line one is divided into parallel, vertical and cross three categories, using ant colony algorithm, adhere to the "detailed layout, optimized network" thoughts, starting from the purpose of the subway and bus coordination complementary, in order to promote the benign development of the subway and bus as the ultimate goal, related to metro line 1 bus routes have been adjusted and optimized.In this paper, based on the principles of line adjust relevant, need to adjust the line article46, based on the distance between the site and passenger OD, optimization. Optimization results in terms of length of bus, passenger transfer coefficient are increased, for thedevelopment of subway and bus, in the future to lay the good foundation.
