Over the past decade, the world has witnessed growing threats to the safety and security of cities and towns. These threatens, in terms of traffic accidents, traffic jam, environmental pollution, crime incidents, etc, have all brought severe challenges to place-making and management on urban space. Streets, the public space where people commute, walk, go shopping, stay, and live, has played a key role in making our cities safe and secure for generation to come. Topics of street security cover a series of urban safety issues, such as transportation safety, defense and security, psychological security, and so on, which are worthy of attention by city planners and urban designers. Streets are important elements in downtown revitalization. Among the globe, infilled development of commercial and retail functions in old downtown cities has being contested as an effective revitalization approach to promote the vitality of neighborhood with various functions, but also as a growing threaten to local safety as well as an overburden to streets according to increasing tourist and traffic flows. There are abundant researches on gentrification trends as well as discussions on urban revitalization approaches. As the basic demand of local residents and immigrants, the security issues, however, are in lack of discussion. Although there is common sense that the entering of immigrants, commerce, and tourists have increased unsafety risks to local neighborhoods, very few scholars have investigated this topic and make scientific verification.EnglishopenAccessconferenceObject1002-1009
