摘要
针对城际铁路客流分担率估计中存在信息不完备、致使运用参数方程求解很困难的情况,提出了运用改进后的信息扩散方法对客流分担率进行估计,又用数据验证了改进后的估计精度有所提高.
In order to deal with the situation that lots of incomplete samples in sharing ratio estimate information render difficulty in parameter equation solution, using improved information diffusion method to estimate the sharing ratio of intercity railway passenger flow is proposed. Furthermore, this paper approves that the precision has enhanced by practical data.
