Unfortunately , the theory of traditional prediction always ignores this essential relationship , which results in the shortage of a systematic prediction . therefore , the primary problem confronting the predictors in the field of transportation does not lie in how to explore the new statistical prediction model but in the establishment of a systematic theory about prediction 傳統(tǒng)預(yù)測(cè)理論忽略了這種實(shí)質(zhì),因而缺乏一種系統(tǒng)預(yù)測(cè)的理念,所以目前擺在道路運(yùn)輸預(yù)測(cè)者面前的首要問(wèn)題,不在于如何探索多么新穎的統(tǒng)計(jì)預(yù)測(cè)模型,而在于構(gòu)造一種系統(tǒng)預(yù)測(cè)的理論體系。
