My administration will begin immediately and work urgently to address the transportation dilemma that complicates our lives and threatens our prosperity. Together, let us find answers through a dialogue that is shaped not simply in terms of dollars and cents, but also by new solutions and common sense. A lack of coordination and planning has us stuck where we are today. -Virginia Governor Tim Kaine, Inaugural Address, 2006 Prologue
Summary of Accomplishments • Reviewed practices of scenario-based planning • Assessed the needs of regional transportation agencies in long-range planning • Developed a scenario-based analysis of the regional impacts of transportation policies • Designed an Excel workbook • Demonstrated the analysis in the Roanoke region with the twenty-one multimodal policies of VTrans2025

Types of Scenarios • Spatial • Economic • Demographic • Number of households, in/out-migration • Other • Environmental • Availability of energy resources • National emergencies • Natural disasters • Workforce
Spatial Scenarios • Urban core repopulates • People go to urbanized areas to live and work, net population unchanged • Public transportation increases, clean transportation • Sprawl accelerates • Private automobile become main mode, vehicle miles traveled increases • Land consumption, energy usage increase, resource depletion • Information technology amenities grow • More workers telecommute so sprawl continues • Flexible work hours result in justifying transit service to certain areas • Region undivided • Shift job and household growth from west to east • Transit oriented development • More people live and work closer to transit Sources: www.dvrpc.org/LongRangePlan/2030/WhatIfFinal.pdf www.mwcog.org/uploads/committee-documents/v1taWF820050929141940.ppt
Economic Scenarios • Regional economy strengthens • Many workers move to region, sprawl continues • Global trade intensifies • Population decreases, increased use of automobiles • Energy cost rises • People relocate to more transit-oriented locations • Decreased use of automobile, air quality increases • Infrastructure investment expands • May draw people to area in the long run Sources: www.dvrpc.org/LongRangePlan/2030/WhatIfFinal.pdf www.mwcog.org/uploads/committee-documents/v1taWF820050929141940.ppt
Demographic Scenarios • In-migration increases • Total population increases, decreased use of auto • Out-migration increases • Population decreases, increased use of auto • More households • Increased household growth to balance forecast job growth Sources: www.dvrpc.org/LongRangePlan/2030/WhatIfFinal.pdf www.mwcog.org/uploads/committee-documents/v1taWF820050929141940.ppt
Other Scenarios • “Green” region emphasized • Use of public transit, bike, etc. • Crisis of national significance occurs/ homeland security tightened • Sprawl accelerates, shun public transportation • Airlines suffer, intermodal connection not emphasized • Carbon constrained future • Energy constrained future • Global price shocks and shortages Sources: www.dvrpc.org/LongRangePlan/2030/WhatIfFinal.pdf www.mwcog.org/uploads/committee-documents/v1taWF820050929141940.ppt
Methodology Components Performance Goals Transportation Policies Future Scenarios
VTrans Statewide Policies • Twenty-one policies of VTrans and Office of Multimodal Transportation Planning • Sample of policies • P.4 – Fund rail • P.6 – Strengthen planning and modeling • P.24 – Going green (specific to region) • P.23 – Improve bicycle and pedestrian paths (specific to region)
MPO Interest in VTrans Policies Source: VTrans survey 2008
Future Scenarios • Used nineteen scenarios based on studies throughout the U.S. • Focused on five scenarios for the region in our case study • S.2 – Sprawl accelerates • S.17 – Retirement • S.18 – Natural disaster • S.3 – IT amenities grow • S.19 – Decrease in air quality
MPO Interest in Future Scenarios Source: VTrans survey 2008
Transportation Goals • Six high level goals with 34 performance criteria • High level criteria: • C.1 – Safety and Security • C.2 – Preservation and Management • C.3 – Efficient Movement of Goods and People • C.4 – Economic Vitality • C.5 – Quality of Life • C.6 – Program Delivery Source: VTrans 2025
Results are useful to group policies by performance Results are useful to group policies by upside or downside sensitivity to scenarios Decision making by VTrans and MPOs is informed by choices of scenarios, policies, and performance criteria Interpretation of Results
Summary of Accomplishments • Reviewed practices of scenario-based planning • Assessed the needs of regional transportation agencies in long-range planning • Developed a scenario-based analysis of the regional impacts of transportation policies • Designed an Excel workbook • Demonstrated the analysis in the Roanoke region with the twenty-one multimodal policies of VTrans2025
Recommendations • Deploy Excel workbook for survey of additional regional organizations • Collate the results in support of VTrans2035, comparing the regional impacts of VTrans policies • Provide key input to upcoming summit of transportation thought and vision leaders in Charlottesville, November 2008
Recommendations (cont.) • Costs/resources of deployment • Time to interact by telephone, email, and Excel workbook with regional planners • Time to compile and present comparison comparing regional results • Maintenance of website with Excel workbook • Benefits • Improved coordination of VTrans2035 and the regional planning organizations • Policies that are robust to disruptive scenarios and appropriate to Virginia regions
Next Steps • Study VTrans2035 multimodal corridors • Find the sensitivity of the corridors to VTrans “issues” • Study the sensitivity of VTrans and other statewide policies to future scenarios of climate change • Sea-level rise • Frequencies of storms, flood, drought • Intensities of storms, flood, drought • Demographic/socioeconomic climate impacts
