【摘要】：從流量角度,在假設(shè)車速恒定的基礎(chǔ)上建立了車流運(yùn)行模型,并以該模型預(yù)測(cè)和實(shí)際到達(dá)的流量分布之間的最大流量區(qū)間變異系數(shù)為評(píng)價(jià)指標(biāo),分析了路段上游數(shù)據(jù)收集斷面位置、路段長(zhǎng)度、交通流量和不同轉(zhuǎn)向車流對(duì)預(yù)測(cè)效果的影響.與靜態(tài)勻速模型的對(duì)比分析結(jié)果表明:數(shù)據(jù)收集斷面位置和路段長(zhǎng)度對(duì)模型的預(yù)測(cè)效果影響很小,且不同交通流量和轉(zhuǎn)向車流情況下模型預(yù)測(cè)存在一定規(guī)律性.最后結(jié)合實(shí)際調(diào)查數(shù)據(jù),證實(shí)了模型的有效性.
[Abstract]:From the point of view of flow, a traffic flow operation model is established on the basis of the assumption of constant speed, and the maximum flow interval variation coefficient between the prediction of the model and the actual flow distribution is taken as the evaluation index. The effects of section location, length of section, traffic flow and different steering vehicle flow on the prediction results are analyzed. The results of comparison with the static uniform speed model show that the location of the section and length of the section of the data collection have little influence on the prediction effect of the model, and there are some regularity in the prediction of the model with different traffic flow and steering vehicle flow. Finally, the validity of the model is verified by the actual investigation data.
