Comparison of model networks.

Characteristic	Madison	Gainesville
Network layout	The city center is on an isthmus that separates two lakes (Mendota and Monona). Four lakes (Mendota, Monona, Waubesa, and Wingra) fragment the urban network	The city center is a relatively small urban core located to the east of a major interstate (I-75). No major geographic features fragment the road network
Central business district	Few roadways on an isolated isthmus with limited access options to major highways	Many arterials and streets in a dense grid-like pattern provide many access alternatives, including to I-75
Urban environment	Distributed around two lakes (Mendota and Monona) that bloat the spatial distribution of population and employment	Continuous land mass that concentrates the population and activity in a relatively small area
Urban arterial network	Curved and diagonal routes with few through-connection options	Grid-like and linear routes provide many interconnection options
Suburban arterial network	Heterogenous spatial distribution with limited direct routes to the CBD	Many route options to the main highway (I-75) that connects to the CBD
Rural environment	Roadways are sparsely distributed	Roadways are more densely distributed
Highway access	Access to the interstate system (I-39/90/94) is via few arterials that circumnavigate the lakes	Five major arterials connect to the interstate (I-75)
