【摘要】：在技術(shù)快速發(fā)展,道路網(wǎng)密集度不斷增加,社會服務(wù)高質(zhì)要求的今天,道路交通安全成了各界人士重點關(guān)注的對象,交通界學(xué)者也一直奔赴在交通安全研究工作的前線,為提高其服務(wù)水平不懈努力。然而,如今的道路交通安全問題大多處于“先問題后方案”的模式,運營中的道路還存在許多尚待發(fā)現(xiàn)的安全隱患,嚴重威脅著道路使用者的人身財產(chǎn)安全。對于作為道路安全設(shè)施重要組成部分的道路交通標(biāo)志,反光膜標(biāo)志在低能見度條件下的低視認性帶來濫用遠光燈的問題也極易引發(fā)交通事故,在如此嚴峻的事態(tài)下,發(fā)展具較優(yōu)視認性的LED主動發(fā)光交通標(biāo)志刻不容緩。但如今國內(nèi)外對LED主動發(fā)光交通標(biāo)志視認性的相關(guān)研究成果還較少,相應(yīng)技術(shù)指標(biāo)的研究數(shù)據(jù)尚欠缺,這些都成了該類標(biāo)志推廣與普及的阻礙。本論文以太原市中環(huán)路主路試設(shè)的LED主動發(fā)光指路標(biāo)志及同規(guī)格的反光膜標(biāo)志為研究對象,憑借徠卡S910手持激光測距儀,分別在晝夜條件下展開駕駛員對交通標(biāo)志視認性的試驗研究。然后通過有效試驗數(shù)據(jù)的處理研究,結(jié)合鄧氏灰色關(guān)聯(lián)模型,分析各因素對駕駛員視認交通標(biāo)志的影響情況及各因素影響性的關(guān)聯(lián)度大小,并根據(jù)價值工程理論、經(jīng)濟性評價指標(biāo)及方法,借助實例,對LED主動發(fā)光交通標(biāo)志的經(jīng)濟性進行評價與分析。結(jié)果表明:駕駛員自身特性及環(huán)境條件與駕駛員認讀標(biāo)志信息的效率有著密切關(guān)系;LED主動發(fā)光交通標(biāo)志在白天和夜間時的視認性差異甚微,但其在夜間的視認性明顯優(yōu)于反光膜標(biāo)志;LED主動發(fā)光交通標(biāo)志所創(chuàng)造的價值要遠大于其成本,經(jīng)濟效益優(yōu)越,值得進一步的研究與探討。本論文的研究成果能有效降低道路交通安全事故率,具有一定的發(fā)展與推廣價值,還能為今后在這方面的研究提供相應(yīng)的理論依據(jù),具有一定的參考價值。
[Abstract]:With the rapid development of technology, the increasing density of road network and the high quality requirements of social services, road traffic safety has become the focus of attention of people from all walks of life, and scholars in the traffic sector have also been on the front line of traffic safety research. Make unremitting efforts to improve its service level. However, most of the road traffic safety problems are in the mode of "first problem and then plan". There are still many hidden dangers to be found in the operation of the road, which seriously threatens the personal and property safety of the road users. For road traffic signs, which are an important part of road safety facilities, the low visual recognition of reflective film signs under the condition of low visibility can also easily lead to traffic accidents. Under such a serious situation, It is urgent to develop LED active luminous traffic signs with better visual recognition. However, there are few research results on the visualization of LED active luminous traffic signs at home and abroad, and the research data of the corresponding technical indicators are still lacking, which have become an obstacle to the promotion and popularization of this kind of signs. In this paper, the LED active luminous guide sign and the reflective film mark of the same specification are tested on the main road of Taiyuan Central Ring Road as the research object, with Leica S910 handheld laser rangefinder. The experimental study on the driver's perception of traffic signs was carried out under the condition of day and night. Then, through the processing of effective test data, combined with Deng's grey correlation model, this paper analyzes the influence of each factor on the driver's perceived traffic sign and the correlation degree of each factor's influence, and according to the value engineering theory, The economic evaluation index and method are used to evaluate and analyze the economy of LED active luminous traffic signs with the help of an example. The results show that the driver's own characteristics and environmental conditions are closely related to the efficiency of driver reading sign information. There is little difference in the visual recognition of LED active luminous traffic signs between day and night, but its visual recognition at night is obviously better than that of reflective film signs. The value created by LED active luminous traffic signs is much greater than its cost, and its economic benefit is superior, which is worthy of further study and discussion. The research results of this paper can effectively reduce the accident rate of road traffic safety, have certain development and promotion value, but also provide the corresponding theoretical basis for future research in this field, and have certain reference value.
