Transportation Overview
40
Scenarios

• Four development scenarios evaluated
• A, B, C, and D
• Each scenario was modeled and compared
• Unique Road network for each
• Unique transit network for each

41
Scenario Descriptions

• A - Assumes that future growth and development
  continues under existing trends. Transportation
  investment is largely new or widened roadways,
  includes some hike and bike trails, but minimal
  transit and walking paths.
• B - A rural development pattern will continue,
  many of the new homes distributed in rural
  cluster developments, minimal growth in existing
  cities and villages. Rural cluster developments
  generally result in longer work commutes
  requiring new or widened roadways. This scenario
  will have hike and bike trails but because
  densities are minimal transit and walking is
  limited.
• C - New development occurs primarily in the
  regions villages and small towns, with some
  growth in the main cities of Traverse City and
  Cadillac. This growth pattern, which concentrates
  development in villages, makes better use of
  regional bus, walking, biking, with limited
  roadway widening.
• D - Focuses on encouraging a larger share of
  housing and employment growth in the regions two
  main cities, Traverse City and Cadillac. Includes
  investment in urban bus circulars, walking and
  biking paths. This scenario has the least amount
  of new or widened roadways.

42
Determining Improvements

• Roads that observed Levels of Service at or below
  D were evaluated for improvement.
• Urban roads were widened only to four lanes.
• Rural Roads we widened to four lanes or given
  additional capacity to reflect passing lanes.
• Transit routes were based on development type,
  development density, and dependency (college
  students)

43
Scenario A Improvements

• Road improvements

• Transit Improvements

• 142 new lane miles

44
Scenario B Improvements

• Road improvements

• Transit Improvements

• 86 new lane miles

45
Scenario C Improvements

• Road improvements

• Transit Improvements

• 78 new lane miles

46
Scenario D Improvements

• Road improvements

• Transit Improvements

• 58 new lane miles

Preliminary Corridors

• Based on the scenarios, eight main corridors
  within Traverse area require detailed analysis
• North Shore Dr.
• Front St.
• Division St.
• Airport Rd.
• Garfield
• M 72 East
• US 31 West
• MI 37 South

57
Preliminary Corridors

• Depending on the selected scenario additional
  corridors may be added
• Transit routes, lane configuration, access
  requirements, and traffic operations should be
  considered.
• Model has provided choke points, the detailed
  analysis will provide a list of recommended
  improvements.

Land Use and Transportation Scenario Tradeoffs
59
Scenario TradeoffsAnnual Tons of CO2 Emissions

• What does this mean?
• 172,000 tons of CO2 (the difference between
  scenarios A and D) is equal to the CO2 in over
  1.1million tanks of gasoline.
