“城市大脑”管控下的交通感知及评价调研

Traffic Perception and Evaluation Research under the Control of “Urban Brain”

城市大脑能够统筹协同道路监控、红绿灯等设施的海量数据,计算实时最优交通方案进行监测治理。为探究城市大脑在杭州实施过程中存在的问题、初步开展成效、市民评价等,小组开展了本次调研。运用随机抽样法确定问卷样本数量,通过查阅文献、预调研等方式,确定本次调研主要围绕市民对城市大脑的认知程度、注重方面、未来期待以及市民的出行体验进行调查分析。最后利用基于ACSI的市民注重度模型和结构方程模型对数据进行分析。通过问卷分析发现:1) 市民对城市大脑的认知程度不高,其中性别和文化程度是影响认知情况的重要因素;2) 大部分市民担心城市大脑在运行中发生技术故障或泄露个人隐私;3) 市民最关注最优路线规划功能;4) 提升出行体验是城市大脑发展的必由之路。

Urban brain can coordinate the massive data of road monitoring, traffic lights and other facilities, calculate the real-time optimal traffic scheme for monitoring and management. In order to explore the problems existing in the implementation process of urban brain in Hangzhou, the team con-ducted this survey. We use the random sampling method to determine the number of question-naire samples, through literature review, pre survey and other ways, to determine that this survey mainly focuses on the cognitive level, aspects, future expectations and travel experience of citizens. At last, the data are analyzed by using the model of citizen’s note weight based on ACSI and struc-tural equation model. Through questionnaire analysis, we found that: 1) citizens’ cognition of urban brain is not high, and gender and education are important factors affecting cognition;2) most citizens are worried about technical failure or personal privacy disclosure in the operation of urban brain;3) citizens are most concerned about the optimal route planning function;4) improving travel experience is the premise of urban brain development.
