摘　　要：相对于现行规范中将指路标志地点信息按照行政等级划分的方法,高速公路出入口交通量大小更能客观反映连接城市的交通信息重要程度.基于多条华北地区高速公路出入口交通量数据,使用数据分析软件研究了出入口相对流量与连接城市的行政等级、人口数、GDP、被交道路、城市规模等因素之间的关系,得出了指路标志地点信息重要度计算模型.相对于现行仅依据行政等级划分地名的方法,此模型更加真实地刻画了交通需求(即信息需求度)与地名属性之间的关系,可被用于指导指路标志信息分类及新建高速公路的地点距离标志版面信息规划.Highway traffic volume objectively reflects the importance of the connecting cities'information compared to the method for dividing the location information of the guide signs according to the administrative grade in current specifications,several expressways'traffic volume data in north China were collected in this paper,and the relationship between relative traffic volume and executive rank,number of population,the gross domestic product(GDP),the intersection of roads,the urban scale and other factors of the cities through by highway were analyzed by the data analysis software,and a new type of demand model about guide sign information were established.This model is a true description of the traffic demand(ie,information demand)and the relationship between geographical attributes,in contrast to the current methodology for the division of geographical names based solely on administrative ranks,this model is more in line with the actual situation,which can be used to guide the information classification of guide signs and to plan the layout information of location distance marker in newly built expressway.
