An urban traffic-environment model
An urban traffic environment model

Urban environment pattern depends heavily upon urbantraffic pattern, the balance between traffic (implicit production) and environment leads to the urban sustainable development. An integrated urban traffic-environment model consists of three components of urban production variables (population density, GDP, salary, etc. in blocks), urban traffic variables and urban environmental variables; and two links between urban traffic planning variables and urban environment variables, and between spatial interaction model (SIM) and traffic planning variables as well. The model is quite useful in urban environment impact assessment; urban traffic management; urban sustainable development planning; and urban development decision-making.
