摘要
为了保证在复杂环境下驾驶员发现交通标志后有充足的时间完成标志信息的读取,在分析交通标志使用过程的基础上,提出标志设置的前视距离,并建立约束条件。为进一步确保车辆能够在危险点或分岔口前安全、顺畅地完成车辆行驶状态的改变,基于标志前视距离的约束条件和对目前标志设置方法中存在问题的分析,结合标志设置对路侧安全的影响,建立了新的路侧交通标志设置方法。
The concept of visibility distance of the traffic signs was proposed and the constraint conditions were established based on the analysis of the process of using traffic signs to ensure the driver to have a sufficient time to recognize the information after detection of the traffic signs in the complicated environment. In order to further guarantee the possibility of the vehicle to change the driving condition safely and smoothly before a hazard point or a road intersection, a model for the P d acement of the roadside traffic signs was built based on the constraint conditions for the visibility stance of the traffic signs and the analysis of the problems existed in the present placement method of the traffic signs with consideration of the effect of the traffic sign placement on the roadside safety.
