Remark: In fact, the waiting time interval is a continuous distribution. For simplicity sake, it is discretised and treated as a discrete distribution for analysis. The R mentioned before is a free statistical analysis software.

从ACF和PACF图可以看出,等候时间的ACF和PACF均不显著。

The Ljung Box Test shows that there is no serial dependence among the waiting time interval.作者: 565109318 时间: 2010-3-27 19:38
突然好怀念小学时候,小学门口斜对面有个31路公交车总站……
可惜我已经离开咗3年啦……
当年睇住31路总站变成16路,有种同好朋友永别既感觉……虽然家住金碧,但系好彩,我仲有机会坐31去人民路,不过要转车……作者: gzeratsg 时间: 2010-4-3 15:22
三、估计线路配车数
1、个人主观估计
在所有的观察中,共看见34辆车。而在路上也疑似看见另外一辆车。再估计错过的停场的单班的等等因素,这里面估计有3~5辆车。所以个人主观估计31线配车约38~40台。
