Green Transportation
Enhance travel choices to reduce dependency on single occupant vehicle trips causing… Decrease in Number of Auto Trips Decrease in Trip Length Decrease in Emissions Less Pavement, More Green Space
Environmentally-friendly design and construction
Energy-efficient vehicle fleets

Lessons Learned from Other Lessons Learned from Other CitiesCities
Assessment of All Transit Choices particularly BRT/Streetcar
Comparisons with similar size cities
Comparison with University cities Positive Economic Impact (created $2
to $30 of development for every $1 invested)
Costs / Funding BRT $6-$25M/mile LRT $30-$40M/mile

Short Term (within 5 years) Safety Policy, Process, and Study Related Implementable (TIP/CIP) Corridor implementation for modes
Medium Term (5 - 10 years) Continue connective implementation Implement land use and
transportation mode shifts Long Term (10 - 20 years)
Continuation of medium implementation in key corridors
