【摘要】：駕駛員都有一種普遍的感覺,當(dāng)在某些環(huán)境的路段很容易超速,因為在這些路段環(huán)境下,駕駛員憑借自己的觀察覺得車速并不高,可是實際上車速已經(jīng)很高了；某些環(huán)境路段大家都開得很慢,因為在這些路段駕駛員憑借自己的觀察,覺得車速已經(jīng)很快,可實際車速很低。其實這就是公路空間景觀環(huán)境對駕駛員判斷的影響并最終體現(xiàn)在車速上。所以研究公路空間景觀環(huán)境的對運(yùn)行車速的影響可以更加合理的設(shè)置該路段的合理限速,大幅降低道路安全事故。首先搜集了國內(nèi)外相關(guān)的研究成果,分析了影響運(yùn)行車速的主要原因。影響運(yùn)行車速的原因眾多,若從公路空間景觀環(huán)境的角度來分析的話,主要就是空間圍合程度和道路幾何線形。緊接著在對公路空間景觀環(huán)境進(jìn)行詳細(xì)的劃分,以便詳細(xì)具體的分析不同空間景觀環(huán)境對運(yùn)行車速的影響。然后根據(jù)不同的公路空間景觀環(huán)境利用昆明理工大學(xué)交通仿真實驗室自主開發(fā)的VSDesign軟件構(gòu)建了相應(yīng)的三維虛擬場景,最后利用昆明理工大學(xué)KMRTS駕駛模擬系統(tǒng)平臺進(jìn)行了駕駛模擬試驗。獲取實時采集的相關(guān)數(shù)據(jù)。并對不同道路線形和空間景觀環(huán)境下的運(yùn)行車速數(shù)據(jù)進(jìn)行統(tǒng)計分析。研究結(jié)果表明：隨著空間圍合程度的增大,在直道路段車速會逐漸降低；空間圍合程度的變化對彎道處的車速基本沒有影響。研究結(jié)果為制定道路限速提供了一定的參考依據(jù),同時也為公路運(yùn)行車速的計算提供路基于景觀環(huán)境的修正方法,有利于公路運(yùn)行車速的安全評價。
[Abstract]:Drivers all have a general feeling that it is easy to overspeed on certain sections of the road, because under these conditions, the driver does not think the speed is high, but in fact the speed is already very high. In some environmental roads, everyone is driving very slowly, because in these sections, the drivers, with their own observation, feel that the speed of the road has been very fast. But the actual speed is very low. In fact, this is the impact of the highway spatial landscape environment on the driver's judgment and finally reflects on the speed. Therefore, the study of the impact of the highway space landscape environment on the running speed can be set more reasonably. The reasonable speed limit of the section, First of all, we collect the related research results at home and abroad, and analyze the main reasons that affect the running speed. There are many reasons that affect the running speed, if we analyze it from the view of highway space landscape environment, It is mainly the degree of spatial enclosure and road geometry. Then, in the detailed division of the highway space landscape environment, In order to analyze the influence of different space landscape environment on the running speed in detail, according to different highway space landscape environment, the corresponding 3D virtual scene is constructed by using the VSDesign software developed by the traffic simulation laboratory of Kunming University of Technology. Finally, the driving simulation test is carried out on the platform of KMRTS driving simulation system of Kunming University of Science and Technology. The relevant data collected in real time are obtained, and the running speed data under different road alignment and spatial landscape environment are analyzed statistically. The results show that: with the increase of the degree of space enclosure, The speed of the straight road will gradually decrease, and the change of the degree of space closure has no effect on the speed of the bend. The results of the study provide a certain reference basis for the establishment of the speed limit of the road. At the same time, it also provides a modified method based on landscape environment for the calculation of highway running speed, which is beneficial to the safety evaluation of highway running speed.
