Chromatic Plans for Urban Furniture: The Case of Multicolored Urban Zones

2021
The concept of sustainable cities comes along with the concern of the population’s comfort and must be supported by a coherent sustainable design including landscape and urban planning strategies that contribute to a better use of the cities, reinforcing their identity. Urban furniture is an important part of these strategies, providing information and

Denitrification Potential in Urban Riparian Zones

Journal of Environmental Quality, 2003
ABSTRACTDenitrification, the anaerobic microbial conversion of nitrate NO−3 to nitrogen (N) gases, is an important process contributing to the ability of riparian zones to function as “sinks” for NO−3 in watersheds. There has been little analysis of riparian zones in urban watersheds despite concerns about high NO−3 concentrations in many urban streams.

Procedural modeling of urban zone by optimization

Computer Animation and Virtual Worlds, 2008
AbstractProcedural modeling technology may be applied for constructing a large‐scale urban scene. Most of the previous studies have exploited a grammar‐based modeling method to generate models. Nevertheless, we formulate the urban planning as a constrained layout optimization problem, propose an algorithm to solve the problem, and procedurally generate

Effects of urbanization on direct runoff characteristics in urban functional zones

Science of The Total Environment, 2018
As urbanization processes, the increasing direct runoff caused by land use change has become a major challenge for urban hydrological system. In this study, the impact of urbanization on direct runoff in the Shenyang urban area was investigated using a modified Soil Conservation Service Curve Number model combined with remote sensing.

THE URBAN ENTERPRISE ZONE*

Journal of Regional Science, 1995
ABSTRACT This paper provides an analytical framework of urban enterprise zones in a context of regional development. The direct and indirect impacts of urban enterprise zones on regional economies such as job creation, urban unemployment, agricultural wage and changes in the regional economic structure are analyzed by incorporating the intermediate ...

Optimal urban land use and zoning

Review of Economic Dynamics, 2004
The paper studies the optimal distribution of business and residential land in a circular city. Once the optimum is characterized, we analyze the effect of changes in commuting costs and externality parameters. We also propose policies like labor subsidies, land taxes and zoning restrictions that can implement the efficient allocation as an equilibrium,

A NEW FORMULA FOR FIGHTING URBAN ZONE

Environmental Science & Technology, 1995
Beginning this year, gasoline sold in many parts of the United States will have a different formula than in the past, thanks to new federal regulations designed to curb urban ozone (the main ingredient of smog) and reduce toxic air pollutants from auto exhaust.
