基于游客视角的智慧景区评价体系及实证分析——以南京夫子庙秦淮风光带为例

建设智慧景区,对于景区实现精细化、低碳化、移动化的管理方向,并最终实现"智慧旅游"的发展战略具有重要意义。目前对于智慧景区的探讨多集中于技术、管理和服务层面,尚无文献从游客视角对智慧景区评价指标体系进行研究。本文运用因子分析方法,构建了基于游客的智慧景区评价指标体系,提出应该从景区智能管理系统、信息服务智能系统、智慧游览系统、智慧预报系统、旅游电子支付、景区综合智能系统、景区安全救助智能系统、景区智能交通系统和景区资源保护智能系统9个方面进行智慧景区的建设。在此基础上,运用模糊综合评价方法,以南京夫子庙秦淮风光带为例,进行了智慧景区的实证评价。最后,对夫子庙秦淮风光带智慧景区建设的优势、不足以及对策进行了分析。

It starts at home? Climate policies targeting household consumption and behavioral decisions are key to low-carbon futures

Through their consumption behavior, households are responsible for 72% of global greenhouse gas emissions. Thus, they are key actors in reaching the 1.5 °C goal under the Paris Agreement. However, the possible contribution and position of households in climate policies is neither well understood, nor do households receive sufficiently high priority in current climate policy strategies. This paper investigates how behavioral change can achieve a substantial reduction in greenhouse gas emissions in European high-income countries. It uses theoretical thinking and some core results from the HOPE research project, which investigated household preferences for reducing emissions in four European cities in France, Germany, Norway and Sweden. The paper makes five major points: First, car and plane mobility, meat and dairy consumption, as well as heating are the most dominant components of household footprints. Second, household living situations (demographics, size of home) greatly influence the household potential to reduce their footprint, even more than country or city location. Third, household decisions can be sequential and temporally dynamic, shifting through different phases such as childhood, adulthood, and illness. Fourth, short term voluntary efforts will not be sufficient by themselves to reach the drastic reductions needed to achieve the 1.5 °C goal; instead, households need a regulatory framework supporting their behavioral changes. Fifth, there is a mismatch between the roles and responsibilities conveyed by current climate policies and household perceptions of responsibility. We then conclude with further recommendations for research and policy.

Identifying primary public transit corridors using multi-source big transit data

ABSTRACT

Effective public transit planning needs to address realistic travel demands, which can be illustrated by corridors across major residential areas and activity centers. It is vital to identify public transit corridors that contain the most significant transit travel demand patterns. We propose a two-stage approach to discover primary public transit corridors at high spatio-temporal resolutions using massive real-world smart card and bus trajectory data, which manifest rich transit demand patterns over space and time. The first stage was to reconstruct chained trips for individual passengers using multi-source massive public transit data. In the second stage, a shared-flow clustering algorithm was developed to identify public transit corridors based on reconstructed individual transit trips. The proposed approach was evaluated using transit data collected in Shenzhen, China. Experimental results demonstrated that the proposed approach is a practical tool for extracting time-varying corridors for many potential applications, such as transit planning and management.
