Study On Bus Microcirculation Network Design Under The Block System

Due to the rapid development of the city's civilization,the vehicle's ownership increases dramatically,which generates the further deterioration of the traffic congestion and restricts the sustainable development of our city.Besides the proposal of urban traffic microcirculation,the "block system" is raised in 2016 to solve the traffic congestion and facilitate the evolution in transportation.Under the circumstance,it is necessary to propel the diversified public transportation by alleviating the traffic jam and improving the quality of transportation service.As a result,the bus microcirculation of urban under the "block system" is elaborated on in this thesis and the traffic network planning and designing is focused on.First of all,the concept of "block system",traffic microcirculation and bus microcirculation is analyzed elaborately in this thesis and the characteristics of bus microcirculation under the "block system" are studied.After estimating the interaction between them,we study on the features and the location of the bus microcirculation,and then make a contrastive study on the differences and similarities comparing with the conventional public transportation.Secondly,an analysis is made on the characteristics of the passenger flow concerning the existing bus microcirculation and then divides the traffic districts on a rational basis.What's more,the passage flow is predicted by the research of transportation and the present state of land use in the thesis.Thirdly,according to the deployment rules of bus microcirculation stations,the optimal principle and methods are proposed in this thesis.In addition,with the purpose of forming a transit line aiming to achieve the minimal enterprise cost under the guidance of microcirculation,an mathematics model of transit line is set up in the thesis and further comes up with the corresponding solution algorithm.Lastly,the author expounds on feasibility and applicability of the models involved by some account cases.The network design of bus microcirculation under the "block system" is prospective to a certain degree.This study not only provides a reference for the management department and the planner to relocate the urban bus microcirculation network,but also facilitates the development of bus microcirculation and the relevant research.
