Public transit vehicle Real-Time Scheduling refer to enterprises of public transport find in real time commerial vehicle occur burst accident and lead to not by
When table continues to run at the time of according to plan, enterprises of public transport make rapidly reasonable scheduling decision, so that when subsequent public transport operation
Section can normally be run.The bus dispatching system of traditional enterprises of public transport is by control room and composition of personnel of arranging an order according to class and grade, by public transport line
The dispatcher of road is rule of thumb and the arrival situation of vehicle formulates operation plan daily, during practical bus operation, also
Dispatcher's schedule vehicle frequency and shift are relied primarily on, but during actual operation, a plan may not be able to keep up with changes,
Merely indiscriminately imitate arrange properly scheduling strategy (in static scheduling mode include issue timetable layout, transport power arrangement etc.) be can not
Can.There are different degrees of interference to existing operation plan for traffic congestion, bad weather, adverse events, as far as possible close to original
Gap between starting scheme, as far as possible diminution actual conditions and plan is that we to be paid close attention to.Reduce this gap
Best approach be exactly to implement dynamic dispatching, i.e. Real-Time Scheduling.Traditional bus dispatching adaptability to changes based on scheduling empirical mode

Algorithm solves the dynamic logistics Distribution path Optimized model under complex environment based on real time information, to realize GPS/
The dynamic to logistics distribution process and vehicle operating path may be implemented in real-time dynamic vehicle scheduling under GIS collaboration, this method
Adjustment and optimization, but genetic algorithm is more sensitive to parameters such as initial population and maximum the number of iterations, and is easily trapped into
Locally optimal solution not can guarantee global optimum.
For another example document " the single line public traffic vehicles schedule Study on Problems based on hybrid metaheuristics " has studied based on mixing
The single line public traffic vehicles schedule problem of heuritic approach establishes a kind of public transport combined schedule mould that uplink and downlink departure frequency is different
Type.The whole vehicle scheduling of the models coupling and local train scheduling, and carried out the hypothesis for being more in line with actual conditions.For the tune
Model is spent, the hybrid metaheuristics that a kind of particle swarm optimization algorithm and pattern search algorithm combine, the algorithm energy are proposed
Effectively particle swarm algorithm is avoided to fall into local optimum.But the fusion of two kinds of algorithms is easy that the computational efficiency of algorithm is made to be difficult to reach need
It asks, when especially vehicle scale is larger.
