19 Travel Simulation Model Bookend Alternatives: A range of options is being evaluated in CISTMS. The bookend alternatives are intended to represent the outer limits of that range. Neither the Current Plan nor the Outer Belt option is currently proposed. Different options may be recommended for different corridors.

Parsons Brinckerhoff LAND USE MODEL Prepared by: HNTB Corporation Cambridge Systematics, Inc. Parsons Brinckerhoff

26 LUCI: Land Use in Central Indiana Model to predict future patterns of urban development for the Central Indiana region Purpose not to produce best forecast but alternative scenarios Scenarios reflect policy choices, including restrictions on development, utility expansion Scenarios reflect alternative assumptions for future development, including population growth, density and accessibility preferences

27 LUCI/T Model Created for CISTMS land use analysis Restricted to nine-county area (from original 44 counties) Uses travel time* rather than distance for employment accessibility Uses traffic analysis zone employment data* *From regional travel simulation model

28 Urban Development 2000 Existing (Base Condition) 2025 Current Plan (Minimum Change) 550 sq.mi. urban848 sq.mi. urban

29 2025 Urban Development Current Plan (Minimum Change) Outer Belt (Maximum Change) 848 sq.mi. urban 2,521 pop./sq.mi. 849 sq.mi. urban 2,520 pop./sq.mi.

30 Possible Reasons for Small Differences The existing base of county to county commuting trips is limited. Urban development Fringe does not reach outer belt alignment (even in 2040). Households have better employment access at edge of urban fringe than from outer belt. Major travel time benefits between locations along outer belt, not to and from existing activity centers.

32 Peer City Analysis Literature Review – Beltways and Land Use Land use impacts relate to beltway function Employment location more important than road (beltway) location Land use affected by commuting time budget Development influenced by proximity of beltway to urban edge Many factors besides transportation determine patterns of growth and sprawl Literature Review – Beltways and Land Use Land use impacts relate to beltway function Employment location more important than road (beltway) location Land use affected by commuting time budget Development influenced by proximity of beltway to urban edge Many factors besides transportation determine patterns of growth and sprawl

33 Peer City Analysis Selected Peer CitiesPopulation Houston, TX4,670,000 Boston, MA3,407,000 Charlotte, NC1,499,000 Nashville, TN1,231,000 Indianapolis MSA population is 1.6 million Selected Peer CitiesPopulation Houston, TX4,670,000 Boston, MA3,407,000 Charlotte, NC1,499,000 Nashville, TN1,231,000 Indianapolis MSA population is 1.6 million

34 Peer City Analysis Conclusions – Urban Sprawl & Beltways 1.Urban growth, economic expansion and the trend of decentralized development prompts urban sprawl concerns nationwide 2.Research is inconclusive regarding direct relationship of outer belts with urban sprawl 3.Beltways (and all freeways) impact the location of development, but its character and intensity is influenced by land use planning and zoning Conclusions – Urban Sprawl & Beltways 1.Urban growth, economic expansion and the trend of decentralized development prompts urban sprawl concerns nationwide 2.Research is inconclusive regarding direct relationship of outer belts with urban sprawl 3.Beltways (and all freeways) impact the location of development, but its character and intensity is influenced by land use planning and zoning

35 Peer City Analysis Conclusions – Urban Sprawl and Planning 1.Land Use Planning and early zoning is key to orderly growth and development 2.Local planning is key since land use policies are determined locally 3.Inter-jurisdictional participation is a necessity Transportation objectives are regional, but land use impacts are local.
