【摘要】:隨著我國(guó)國(guó)民經(jīng)濟(jì)的快速發(fā)展,高速公路的建設(shè)取得了卓越的成就。隨著路網(wǎng)密度的增大,高速公路上互通式立交越來(lái)越多,,導(dǎo)致立交之間的間距難以滿足相關(guān)規(guī)范的要求。如果互通式立交之間的間距過(guò)小,其交通安全性將難以得到保證。為了提高互通式立交的設(shè)計(jì)合理性和安全性,本文對(duì)互通式立交的安全間距進(jìn)行研究。 首先對(duì)相鄰互通式立體交叉的間距進(jìn)行定義,并從路網(wǎng)密度、匝道幾何特性、交通流特性、交通標(biāo)志設(shè)置和駕駛舒適性等方面對(duì)此間距進(jìn)行分析,把立交安全間距的研究分為加速車道、凈間距和減速車道三部分。 然后通過(guò)對(duì)比國(guó)內(nèi)外變速車道設(shè)置的規(guī)范和計(jì)算方法,結(jié)合國(guó)內(nèi)車輛性能與交通狀況,以大貨車、小客車為研究對(duì)象分別對(duì)變速車道長(zhǎng)度進(jìn)行分析計(jì)算,提出了以主線與匝道設(shè)計(jì)速度為依據(jù)的變速車道長(zhǎng)度推薦值。 其次通過(guò)對(duì)相鄰立交段內(nèi)變換車道和駕駛行為的分析,把高速公路相鄰立交安全間距分為合流影響區(qū)和分流影響區(qū),利用概率論和可插入間隙等理論,建立了高速公路立交安全間距的計(jì)算模型,并提出了相鄰互通式立交安全凈間距推薦值。 接著利用高速公路交織區(qū)通行能力的分析方法對(duì)互通式立交安全凈間距進(jìn)行系統(tǒng)的研究,得到了交織區(qū)內(nèi)交織車輛、非交織車輛運(yùn)行速度和服務(wù)水平,以交織車輛與非交織車輛速度差為安全標(biāo)準(zhǔn),提出高速公路互通式立交安全凈間距的推薦值。 最后利用本文的研究成果,對(duì)實(shí)際工程中的近距離立交進(jìn)行安全性分析,具有一定的現(xiàn)實(shí)意義。
[Abstract]:With the rapid development of our national economy, highway construction has made remarkable achievements. With the increase of road network density, there are more and more interchanges on freeway, resulting in the gap between interchanges is difficult to meet the requirements of relevant codes. If the distance between interchange is too small, its traffic safety will not be guaranteed. In order to improve the design rationality and safety of interchange, this paper studies the safety spacing of interchange. First of all, the distance between adjacent intersecting is defined, and the distance is analyzed from road network density, ramp geometry characteristics, traffic flow characteristics, traffic sign setting and driving comfort, etc. The research on safety spacing of interchange is divided into three parts: acceleration lane, net distance and deceleration lane. Then, by comparing the specifications and calculation methods of speed change lane setting at home and abroad, combining the performance of domestic vehicles and traffic conditions, taking large freight cars and minibuses as research objects, the length of variable speed lane is analyzed and calculated respectively. Based on the design speed of main line and ramp, the recommended value of lane length is put forward. Secondly, through the analysis of the changing lane and driving behavior in the adjacent interchange section, the safe spacing of the expressway adjacent interchange is divided into the confluence impact area and the distributary influence area, and the theory of probability and pluggable gap are used. The calculation model of the safe spacing of expressway interchange is established, and the recommended value of the safety net spacing of the adjacent interchange is put forward. Then, by using the analysis method of the capacity in the interleaving area of expressway, the safe net spacing of interchange is systematically studied, and the running speed and service level of interleaved and non-interleaved vehicles are obtained. Taking the speed difference between interleaved and non-interwoven vehicles as the safety standard, the recommended value of the safety net spacing of expressway interchange is put forward. Finally, using the research results of this paper, the safety analysis of the close-distance interchange in practical engineering is carried out, which has certain practical significance.
