【摘要】：高速公路服务区,是指为了满足高速公路上驾乘人员的需求和完善高速公路的服务功能而建设的,为旅客和车辆提供交通安全保障、休息服务等内容的服务设施。高速公路服务区作为一种特殊的道路环境,与服务区外普通路段相比有其自身的特殊性,无论是在交通环境特征方面,还是驾驶员视觉环境特征方面均与普通路段都存在很大的差异。高速公路服务区交通标志是与驾驶员息息相关的,是实现服务区系统既定功能的关键因素,在停车选择过程中,交通标志提供重要的实时诱导,确保驾驶员顺利进出服务区,保证区域内部及周边交通的通畅。因此结合驾驶员视觉特性研究服务区交通标志的设置,能够完善服务区标志系统,给驾驶员创造更舒适便利的道路行车环境。首先,分析了高速公路服务区交通标志的特征,结合服务区区域的特点,提出高速公路服务区交通标志的结构层次、布局原则以及设置参数。通过对驾驶员视觉特性的讨论,确定出高速公路服务区驾驶员的视觉行为表征参数,并分析了驾驶员在行车过程中的交通标志视认过程。其次,对高速公路服务区进行交通流统计调查,得出服务区的交通流特性,利用Smart Eye Pro 5.7型非侵入式眼动仪记录了驾驶员在服务区不同路段行驶过程中的眼动参数,并以各个路段驾驶员的注视区域、注视点分布、注视持续时间等眼动参数作为评价指标,分析了驾驶员在各个路段行驶过程中的眼动变化规律,在此基础上研究了驾驶员在服务区行车过程中的寻路特征。最后,在高速公路服务区交通标志需求分析的基础上对交通标志的具体设计进行了研究,提出优化模型进行交通标志版面的优化设计,具体设计了各等级交通标志的版面。主要针对三级交通标志对服务区交通标志布局进行了研究,建立了可行的优化模型,结合问题的特点和模型的情况确定了遗传算法作为求解算法,在此基础上分析了交通标志前置距离计算模型。
[Abstract]:Expressway service area is to meet the needs of drivers on the highway and improve the service function of the highway and to provide traffic safety protection for passengers and vehicles. As a special road environment, the expressway service area has its own particularity compared with the common section outside the service area, whether in the traffic environment characteristics. The traffic sign of expressway service area is closely related to the driver and is the key factor to realize the established function of the service area system. In the process of parking selection, traffic signs provide important real-time guidance to ensure the smooth entry and exit of drivers in the service area. To ensure the smooth traffic in and around the area. Therefore, combining with the visual characteristics of drivers to study the setting of traffic signs in the service area, can improve the service area sign system. To create a more comfortable and convenient driving environment for drivers. Firstly, the characteristics of traffic signs in expressway service area are analyzed, combined with the characteristics of service area, the structural level of traffic signs in expressway service area is put forward. Layout principles and setting parameters. Through the discussion of drivers' visual characteristics, the visual behavior parameters of the drivers in expressway service area are determined. And analyze the traffic sign recognition process of drivers in the course of driving. Secondly, the traffic flow characteristics of the service area are obtained by the traffic flow statistical investigation in the expressway service area. The eye movement parameters of drivers in different sections of service area were recorded by using Smart Eye Pro 5.7 non-intrusive eye movement instrument. Eye movement parameters, such as fixation point distribution, fixation duration, etc., are used as evaluation indexes to analyze the change of eye movement of drivers in each section of the road. On this basis, the driver in the service area in the driving process of the road finding characteristics. Finally, on the basis of the expressway service area traffic sign needs analysis on the basis of the specific design of traffic signs were studied. The optimization model is put forward to optimize the layout of traffic signs, and the layout of traffic signs of each grade is designed. The traffic signs layout of service area is mainly studied for the third grade traffic signs. A feasible optimization model is established, and the genetic algorithm is determined to solve the problem according to the characteristics of the problem and the situation of the model. On this basis, the traffic sign pre-distance calculation model is analyzed.
