An intra-urban hierarchy of activity centers interconnected by non-motorized and public transportation is broadly believed to be the ideal urban spatial structure for sustainable cities. However, the proper hinterland area for centers at each level lacks empirical study. Based on the concentric structure of everyday travel distances, working centers, shopping centers, and neighborhood centers a...

An analysis pattern is any part of a requirement analysis specification that can be reused in the design of other information systems as well. Urban management systems (e.g.: Tax Control Systems, Urban Transportation System) are implemented in a similar way for many counties. This paper proposes three analysis patterns that make possible the reuse of geographic database design for urban area pl...

Virtual 3D city models represent spatial and geo-referenced urban data by means of 3D geovirtual environments that basically include terrain models, building models, vegetation models as well as models of roads and transportation systems. In general, these models serve to present, explore, analyze, and manage urban data. As a characteristic element, virtual 3D city models allow for visually int...

Mostly because of increased speed and decreased costs of communication and transportation, cities are growing increasingly diverse in their population. Consequently, cultural factors have taken center stage in the understanding of urban mental health. This article will focus on the main approaches to urban mental health and briefly summarize the 3 lines of research in this area. It will then di...

Urban planning experts often use computer models to help evaluate alternative land use policies, particularly as they interact with transportation and environmental decisions. The greatly increased data volume provided by new land use models makes their effective use difficult without suitable visualization tools. We present UrbanView, a visualization system for urban modeling, and describe a u...

Workshop report on the potential for growth and innovation in commercial scale urban agriculture at the nexus of food, energy, water, and transportation systems. Abstract Commercial scale urban agriculture is an intriguing concept that could fulfill the demand for fresh, affordable food that is produced, processed, and distributed through more sustainable and resilient supply chains. While rura...

Determinant factors of dengue global epidemiology trends include, but are not limited to: 1) demographic changes including population growth, economical trends in tropical countries and land use patterns; 2) increased urban population size and density due to rural to urban migration 3) modern transportation with increased movement of people, commodities, animals, vectors and pathogens; and 4) c...
