Environmental safety evaluation of geopark based on CPTED concept and fuzzy comprehensive analysis

Abstract

In recent years, with the increasingly popular and openness of Geoparks, Environmental safety has become a major concern for sustainable geo-tourism. It is therefore necessary to conduct an environmental safety performance evaluation for promoting geo-tourism development. In order to identify and figure out the factors influencing the tourists’ environmental safety perception, an index system was established based on six principles of Crime Prevention Through environment design (CPTED) theory. A Questionnaire was adopted for data collection, and the overall evaluation value and concrete index scores at all levels were obtained via the fuzzy comprehensive analysis and Importance-Performance analysis. Empirical results show that: (1) tourists’ perception of environmental safety performance in Shilin Park from high to low was: image and maintenance, Natural Surveillance, territoriality, Access control, Activity support and target hardening; (2) The sub-factors influencing tourists’ safety perception mostly include electronic monitoring device, Lighting system, Public safety management, Road layout, environmental sanitation; While attention should be paid on the following aspects including park service center, inter-personal surveillance, surrounding environment, unobstructed view, parking lot, Signpost, for they are considered as high-importance items with relatively poor performance. Based on the analysis, three optimization measures were proposed, including optimizing the layout and design of each space, strengthening the deterrent force of the park and maintaining a good environmental image. This research provides useful suggestions for Geopark decision-makers on determining the priority of Geopark spatial planning and management, as well as achieving the optimal allocation of resources to promote the sustainable development of Geopark.

A Personalized Recommendation Technique for Travel Route Based on Fuzzy Consistent Matrix

“…e authors conducted several experiments and the acquired outcomes indicate that the offered personalized recommendation system can effectively solve the problem of scarce tag data, and the recommendation performance of the trained recommendation system is significantly good. However, the accuracy of the personalized tourism recommendation algorithm is poor [5][6][7]. us, improving the efficiency, as well as, accuracy of such recommendation systems is the focus of this research.…”

“…e process continues to learn and obtain matrices P and Q through the random gradient descent method, and then predict score r ui . e user model not only considers the basic attributes of users, but also comprehensively considers the user project interaction information, and adds the factor of collective intelligence to the user model [7]. e user u is expressed in the characteristic matrix P as:…”

“…In fact, it measures the recall rate of the tourist route recommendation algorithm [29]. Assuming that the set of tourist attractions recommended by the recommendation system to users is known and the set of tourist attractions actually liked by users is T(u), then the recall rate of the recommendation results is defined as given by formula (7):…”

“…Experiments of state-of-the-art literature demonstrate that this personalized recommendation algorithm and method can resolve the issue of scarce tag data, and the recommendation performance of the trained recommendation system is significantly good as compared to other techniques. However, unfortunately, the accuracy of the personalized tourism recommendation procedure is poor [5][6][7].…”

Safety and Security Assessment of Tourist Destinations: A Field Study in a Nigerian Geopark

“…Atlas, 2013;Armitage & Joyce, 2017;Armitage, 2016;Odufuwa, et al, 2019; have shown that, how a place is physically planned, designed, built, rebuilt, maintained, and managed contribute to its safety, security and vitality. Equally, Chen, et al, (2021) only focused on planning and design (Crime Prevention through Environmental Design [CPTED]) while neglecting other established dimensions such as communication and documentation, people (e.g. management) among others.…”
