【摘要】：驾驶员都有一种普遍的感觉,当在某些环境的路段很容易超速,因为在这些路段环境下,驾驶员凭借自己的观察觉得车速并不高,可是实际上车速已经很高了；某些环境路段大家都开得很慢,因为在这些路段驾驶员凭借自己的观察,觉得车速已经很快,可实际车速很低。其实这就是公路空间景观环境对驾驶员判断的影响并最终体现在车速上。所以研究公路空间景观环境的对运行车速的影响可以更加合理的设置该路段的合理限速,大幅降低道路安全事故。首先搜集了国内外相关的研究成果,分析了影响运行车速的主要原因。影响运行车速的原因众多,若从公路空间景观环境的角度来分析的话,主要就是空间围合程度和道路几何线形。紧接着在对公路空间景观环境进行详细的划分,以便详细具体的分析不同空间景观环境对运行车速的影响。然后根据不同的公路空间景观环境利用昆明理工大学交通仿真实验室自主开发的VSDesign软件构建了相应的三维虚拟场景,最后利用昆明理工大学KMRTS驾驶模拟系统平台进行了驾驶模拟试验。获取实时采集的相关数据。并对不同道路线形和空间景观环境下的运行车速数据进行统计分析。研究结果表明：随着空间围合程度的增大,在直道路段车速会逐渐降低；空间围合程度的变化对弯道处的车速基本没有影响。研究结果为制定道路限速提供了一定的参考依据,同时也为公路运行车速的计算提供路基于景观环境的修正方法,有利于公路运行车速的安全评价。
[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.
