Description
Technical field
The present invention relates to belong to a kind of public transport problem identification of lines technology.
Background technology
It is external more early in the starting of transit network planning field, mainly network is carried out with optimized algorithm by setting up model
Adjustment and optimization.Including：Mandl uses approximate data within 1979, seeks more excellent feasible solution, and is combined with empirical method, in gauze
It is adjusted after first formation.Patuaik in 1998 etc. is proposed with genetic Algorithm Design public transport network.The model is with public transport
Passenger's travel cost and the minimum target of running cost summation, firstly generate circuit and alternatively collect, then carried out by genetic algorithm
It is preferred that.Genetic algorithm is being used to propose a kind of new calculating fitness letter when public traffic network optimizes by Maurizi in 2000 etc.
Several methods.
Into 21 century, some researchs are from the microcosmic layout of network, using mathematical combination optimization method to public transport network
Layout expansion research.Lee in 2005 etc. gives the alternative manner for solving public traffic network design problem, it is contemplated that aggregate demand is fixed
In the case of public transport demand change.Duff-Riddell in 2005 etc. proposes many using standardised transportation network model Software for Design
The method of formula public traffic network.
China starts late in terms of bus line network ad- justment optimization, but also achieves some substantial progress, establishes
Relevant evaluation system and model are used to optimize.Such as：1999, Han Yin, Li Weibin, Li Xiaofeng etc. constructed transit network planning
PSO algorithm mathematics models, propose pre-selection one by one and search, optimization networking algorithm, rate that target is that average riding distance is most short, passenger goes directly
The average daily load factor highest of highest, gauze, and several cities have been carried out with the optimization of public transport network using the optimization system, and from skill
Art index, Social benefit and economic benefit multi-angle are evaluated optimum results., Hu Qizhou, Shi Qin, Zhang Wei in 2005
China, Zhang Aiping urban public traffic network is optimized with quantitative analysis method method targets and constraints represents with specific function,
On the basis of defining ideal scheme, using object function as element index set, using alternative as domain collection, each alternative side is obtained
Case to ideal scheme two-dimensional distance, by apart from size, to schemes ranking, the preferred plan of line network optimization can be handed over by obtaining city.
For now, the thinking of routine bus system line optimization adjustment is utilized about theoretical and website optimization side
Method, resident's public transport OD is reasonably assigned in public traffic network, forms optimization flow distribution, under certain constraints, is used
Various optimization methods produce optimum line network.And in China's regular public traffic circuit adjusting and optimizing method, be substantially to grind
Study carefully based on transit network planning, establish more mathematic optimal model, and these researchs belong to theoretical research substantially, set up
Mathematic optimal model be difficult solve, for practical application aspect line adjustment in terms of research it is still less.
But, can for a long time, greatly due to the foundation of public transport E-payment system, global position system under current conditions
Obtain to scope travelling OD data, the overall trip speed data of each actual public transit vehicle.How existing new data are combined
Resources supplIes, studying finer, enforceable routine bus system public bus network readjustment technology turns into active demand.
The content of the invention
