DRC bus operation cycle optimization corresponding to passenger demand characters
摘要
Abstract
The optimization method of the running cycle is studied according to the charac-ters of passenger demand when the single-bus and double-cycle mode is adopted by DRC bus.Firstly,passenger demand characters are described by the six dimension array.Second-ly,the passenger utility function is rebuilt considering the uneven distribution of passengers and the cancel reservation and so on,and then the passenger and operator total cost function is built.The optimization model of the running cycle is set up where the passenger departure time window requirement,vehicle capacity,etc.are all considered as conditions while the minimum total cost is the target.The genetic algorithm is devised to obtain the best period. A set of experiment are carried out.From these experiments,the best DRC operating cycle changes with the proportion of passengers and cancellation of booking passengers,the more passengers cancel the reservations,the longer the cycle length.And under the same passen-ger number,the longer the total operating cycle length,the greater the total cost.关键词
