This paper investigates the necessity of detailed surface representation in order to generate a feasible platform for the detailed simulation of urban runoff and surface flooding caused by heavy rainfalls. In recent years, urban flooding has become one of the major environmental hazards and it has caused damage to the buildings and properties over billion of Euros. Expansion of urban catchment ...

Since the number of urban residents is rapidly increasing, especially in developing countries, relatively cheap and fast methods for modeling and mapping such cities are required. Besides the creation and updating of maps from sprawling cities three dimensional models are useful for simulation, monitoring and planning in case of catastrophic events like flooding, tsunamis or earthquakes. With t...

INTRODUCTION The concept of “urban sprawl” has become so popular in American planning and design literature that it has produced its own dedicated lexicon of specialized terms. Words like “asphalt nation”, “McMansions”, and “lollipop suburbs” define the conditions of low-density, automobile-dependent land use patterns that characterize the American landscape with ever greater degrees of specifi...

PURPOSE To determine the relationship between urban sprawl, health, and health-related behaviors. DESIGN Cross-sectional analysis using hierarchical modeling to relate characteristics of individuals and places to levels of physical activity, obesity, body mass index (BMI), hypertension, diabetes, and coronary heart disease. SETTING U.S. counties (448) and metropolitan areas (83). SUBJECTS...

Smartphone technology enables dynamic ride-sharing systems that bring together people with similar itineraries and time schedules to share rides on short-notice. This paper considers the problem of matching drivers and riders in this dynamic setting. We develop optimizationbased approaches that aim at minimizing the total system-wide vehicle miles and individual travel costs. To assess the meri...

The 2-degree guardrail of global warming, together with accelerating urbanization and growing scarcity of oil, demands a redesign of todays’ sprawling cities in order to limit greenhouse gases and bring about efficiently built-up structures. In 2001, 42 percent of commuter paths within Vienna are traveled by private cars. This week-daily, recurring traffic pattern causes tons of Co2 and support...

While many studies on urban compactness measured built-up area (intensity), this study explored population density in forms of gradients. Also, medium and small cities (in case, municipalities due to having autonomous economies), through inquiring their characteristics common, could provide early insights for anticipating further growths. Density database was made, combined with cadastral data....

The paper attempts to evaluate Oregon’s and Portland’s growth management policies as for their tradeoffs between effectiveness in containing urban sprawl impacts on housing markets property values. Carruthers argued that order correctly policies, it is necessary jointly consider effects development patterns, land markets, the fragmentation of use controls. Nowadays, we have sufficient empirical...

The U.S. population is increasingly spreading out, moving to the suburbs, and migrating from the Rust Belt to the Sun Belt. This paper uses recent household-level data sets to study some of the environmental consequences of population suburbanization. It measures the increase in household driving, home fuel consumption, and land consumption brought about by population dispersion. Suburban house...
