Final answer:
The Urban Realms Model is characterized by a polycentric structure with multiple centers, nodal development around key amenities and transportation hubs, and multiple business districts, marking it distinct from traditional urban models.
Step-by-step explanation:
The Urban Realms Model is a contemporary urban growth model that reflects the spread of urbanization in the context of a growing reliance on the automobile, and greater levels of geographic and economic decentralization. When giving 3 characteristics of the Urban Realms Model, one could point to the following features:
- Polycentric Structure: This refers to a city landscape that has multiple centers or 'nuclei' that serve as focal points of activity. Unlike the traditional single urban core, in this model there are various centers for finance, industry, and retail scattered throughout the urban area.
- Nodal Development: Within the urban realms, development tends to occur around key points or nodes, which might be significant business districts, transportation hubs, or large-scale shopping centers and amenities.
- Multiple Business Districts: Contrary to the classic urban model with one central business district (CBD), this model features various business districts that can cater to different commercial and economic activities, creating a network of economically autonomous regions.
The answer to the student's question would therefore be B. Polycentric Structure, Nodal Development, Multiple Business Districts.
