【摘要】：隨著居民出行范圍的不斷擴(kuò)大,公路網(wǎng)承擔(dān)的交通需求迅猛上升,公路網(wǎng)中的復(fù)雜路段、節(jié)點(diǎn)也收到越來(lái)越多的關(guān)注。橋隧路段作為公路網(wǎng)中的重要節(jié)點(diǎn),受到很多主客觀因素的制約,是公路網(wǎng)中一個(gè)重要的交通安全研究節(jié)點(diǎn)。橋隧及其銜接段的行車安全是多因素耦合作用的結(jié)果,對(duì)其中某一因素進(jìn)行分析很難解釋駕駛員在橋隧及其銜接段的行車安全性。目前,國(guó)內(nèi)外對(duì)單個(gè)橋梁、單個(gè)隧道的安全研究很多,但是,從系統(tǒng)的角度,將橋梁、隧道和橋隧銜接段三者作為一個(gè)整體進(jìn)行研究相對(duì)較少。對(duì)橋隧及其銜接段的駕駛員行車安全進(jìn)行研究,對(duì)于提高路段行車安全,降低交通事故率,創(chuàng)建安全交通環(huán)境意義重大。本文采用風(fēng)險(xiǎn)研究的思路,按照“駕駛員行車安全行為風(fēng)險(xiǎn)識(shí)別→駕駛員行車狀態(tài)建模分析→橋隧銜接段駕駛員行車安全風(fēng)險(xiǎn)評(píng)估”的方式,對(duì)橋隧及其銜接段的駕駛員行車安全進(jìn)行研究。以實(shí)驗(yàn)數(shù)據(jù)為基礎(chǔ),首先采用單因素分析法,運(yùn)用定性與定量結(jié)合的方法,識(shí)別出影響橋隧及其銜接段駕駛員行車安全的因素,即風(fēng)險(xiǎn)因素。之后結(jié)合安全熵理論和耗散結(jié)構(gòu)原理,將識(shí)別出的風(fēng)險(xiǎn)因素進(jìn)行正、負(fù)熵影響因素的劃分與賦值,按照不同的道路屬性,對(duì)橋梁、隧道和橋隧銜接段的駕駛員行車安全運(yùn)行過程分別進(jìn)行分析,從定量的角度得到不同位置的風(fēng)險(xiǎn)等級(jí)。接下來(lái)針對(duì)風(fēng)險(xiǎn)評(píng)估模型,構(gòu)建橋隧及其銜接段行車安全評(píng)估體系,采用結(jié)構(gòu)方程評(píng)價(jià)方法,利用AMOS軟件,對(duì)影響駕駛員行車安全的因素進(jìn)行定量標(biāo)定,對(duì)橋隧及其銜接段駕駛員行車安全風(fēng)險(xiǎn)分析進(jìn)行驗(yàn)證。
[Abstract]:With the expanding range of residents travel, take highway network traffic demand rapid rise, complex sections of the highway network, the node has received more and more attention. As an important node of bridge and tunnel sections of the highway network, restricted by many subjective and objective factors, is an important node in the highway network traffic safety of driving. Safety and Bridge cohesion period is the coupling result of multiple factors, it is difficult for a particular factor are analyzed and explained the driver in the driving safety of tunnel and its convergence section. At present, the domestic and foreign research on single bridge, single tunnel safety, however, from the point of view, the bridge, tunnel and bridge connection the three section studied as a whole is relatively small. To study the driver driving safety of tunnel and its convergence section, to improve road traffic safety, reduce the rate of traffic accidents, create 瀹夊叏浜ら，
