【摘要】 交通诱导系统是ITS(Intelligent Transportation Systems, ITS)的重要子系统,其常见的形式是可变信息标志(Variable Message Sign, VMS)交通诱导系统。VMS交通诱导系统是通过安装在路边或公路上方的电子信息显示牌为驾驶员提供与交通相关的诱导信息。VMS的信息包括交通状况、停车、公共交通以及环境等。虽然VMS交通诱导系统自20世纪60年代以来得以发展和广泛应用,但系统的设计很难达到网络上交通负荷尽可能均衡分布从而使道路使用效率最高、用户最优的目标。通过研究国内外文献,从人机工程学理论出发,为了设计VMS系统,实现VMS效益最优,需对系统中的“人”——驾驶员、“机”——VMS设施、“环境”——VMS空间布设进行优化,使之协调工作。因此,论文从驾驶员对VMS的认知性、视认性、可读性和VMS的空间布设进行了研究。认知性是从驾驶员的心理和行为方面进行分析的,包括驾驶员看到VMS发布信息的反应过程以及驾驶员个体属性的不同对VMS认知性的影响。论文利用咨询法和SP调查法对驾驶员属性的影响进行分析,并提出了基于离散选择模型的多元罗吉特模型。视认性和可读性主要表现在VMS发布的交通信息的内容、形式、色彩、字体等方面。论文给出了有关计算VMS视认距离和字体大小的计算公式,通过问卷调查提出了VMS信息发布的最佳形式。空间位置布设是目前最难决策的问题,尽管国内外很多文献对此提出了不同的模型,但是这些模型多是理论上的研究,没有考虑一些随机因素的影响。论文针对不同的路网提出不同的模型,在高速公路和城市主干道组成的路网中应用动态与随机交通网络模型来解决选址问题;在城市网络中应用基于影响指数的数学规划模型;并给出了计算VMS确切位置的计算公式。更多还原

【Abstract】 Traffic guidance system is an important subsystem of Intelligent Transportation Systems, whose common form is Variable Message Sign (VMS) traffic guidance system. VMS traffic guidance system provides the guidance information to drivers by the electronic display brand installed in the roadside or the highway. The VMS information includes traffic situation, parking and environment etc.Although VMS traffic guidance system were developed and applied broadly since 1960’s, but the design of the system is very difficult to reach distribution of traffic loading on the road network balanced and makes the road availability maximal, optimum consumer target.Studying by the document home and abroad, from man-machine engineering theory and for designing the VMS system, need to study the"human"-drivers, "machine"- VMS facilities, "environment"-space spread. Therefore, the paper study on the cognitive quality, readability, visibility and space location of VMS.The cognitive quality of VMS is carries out from driver’s mentality and behavior, including that the driver’s reaction to the information of VMS and the driver’s individual attribute diversity over the cognitive quality of VMS. The paper use of the method of consultation and SP to analysis the impact the driver’s reaction, a disaggregate choice analysis method used to analyze the SP data, and a multinomial logit model (MNL) estimated.The readability and visibility of VMS mainly displays in content, form, color, typeface of the VMS. The paper produced the formulas to calculate the font size and the typeface size, proposed the best form information issue through the questionnaire survey.The space location of VMS is the most difficult problem at present; these models most probably are theoretical research, although many documents has brought forward the different model to here at home and abroad. The thesis brings forward the different model in different road net, the traffic applying development and the random in road net being composed of in express highway and city turnpike road solves coming the network model choosing the location problem; Mathematics plan model applying in the network owing to affecting an exponent in city; And have given the formula to calculate the definite location of VMS’s.更多还原
