摘要/Abstract

摘要： 当前示意性地图表达主要针对公共交通网络,缺乏对道路地图示意性表达可用性评估研究。本文选取景区和街道两个典型道路场景,采用最新的自动示意化方法生成示意地图,以主观问卷调查结合客观眼动试验的方式,评估道路地图示意性表达的可用性。试验结果表明:①示意性表达能够提升道路地图的简化度、清晰度及用户满意度,尤其对于原始道路形状较为复杂的情况;②示意地图中路径形状简化会造成不同路径感知长度差异的改变,从而影响到人们路径抉择行为;③对于路径示意性结果增加了道路网密集程度的情况,会降低示意地图认知效率。本文研究成果有助于道路地图自动示意性表达规则完善和方法优化,能够进一步提升地图示意性表达的实用性。

Abstract: The current schematic map representation is mainly for public transportation networks, and there is a lack of research on the usability evaluation of road map schematic representation. This study selects two typical road scenes: scenic spots and streets, and uses the latest automatic schematic method to generate schematic maps, and uses subjective questionnaire surveys combined with objective eye-tracking experiments to evaluate the usability of schematic representations of road maps. The experimental results indicate: ①The schematic representation can improve the simplification, clarity and user satisfaction of the road map, especially for the situation where the original road shape is more complicated. ②The shape simplification of roads may result in the changes of perceived lengths of different routes so as to influence the human decision-making for route planning. ③If the path schematic result increases the density of road network, the cognitive efficiency of schematic map is reduced. This study can be helpful for the improvements of design rules of automated schematization for road maps and enhances the practicability of schematic representations of maps.
