... 2 Sustainability as an Organizing Principle for Transportation Agencies Anticipating that audiences will include industry practitioners of various levels and disciplines, as well as academic researchers, the research was guided by the intent to support all of the findings, opinions, theory, logic, and case experience to the fullest practical extent in the report -- so that all audiences may find the explanations and sources they need for the material to be useful. This research is not intended to advocate or to predict that sustainability will become a viable overarching organizing principle for transportation.

Given the integrated nature of transportation with the rest of human activity, it is difficult to view the transportation system in isolation.

Policy systems have evolved in this way for generations.

It was noted in interviews and from the literature review that unless state DOTs improve coordination of land use issues with local governments, there would be little hope of improving the sustainability of state transportation initiatives.

... Sustainability as an Organizing Principle for Transportation Agencies 11 The current policy system is far from able to support a TBL sustainable society.
From page 12...
... 12 Sustainability as an Organizing Principle for Transportation Agencies When and if TBL policy systems do evolve, decision models for policy and funding will probably cross organizational and jurisdictional lines as they are currently known. Responsibility for supporting, planning, and executing sustainable TBL will likely extend beyond the traditional jurisdictional and modal organizational boundaries of national, state, and local transportation agencies, because TBL policymaking and resource decisions will involve coordinated selection and execution of strategies by agencies and entities focused on all three bottom lines.
From page 13...
... Sustainability as an Organizing Principle for Transportation Agencies 13 This concept fits well for transportation. Under a TBL sustainability model, a transportation agency would retain full responsibility for transportation services and stewardship by collecting data, developing intelligence, and analyzing transportation needs and how they affect societal sustainability; formulating strategic policy; developing tools for implementation; building support for policy; developing the appropriate structures to implement policy; and ensuring responsiveness and accountability.

Sustainability as an Organizing Principle for Transportation Agencies 17 Key Functional Gaps for Agencies The research team compared the high-level functional characteristics of the current predominant transportation policy systems (Green Transportation, Level 2) to the functional characteristics needed for a TBL Sustainability (Level 4)

... 18 Sustainability as an Organizing Principle for Transportation Agencies • Choosing flexible or adaptive management options. Flexible or adaptive management strategies are based on the insight that knowledge and understanding of social, economic, and environmental conditions is inevitably partial; limited; held in different forms (e.g., data, tacit knowledge and understanding, experiential information)

... Sustainability as an Organizing Principle for Transportation Agencies 19 Although the research shows that significant activity and momentum have been building around green transportation and context-sensitive development, there is no established experience with TBL sustainability to conclusively show that it is practicable. TBL sustainability is a concept whose practicality and results have to be measured over a period of years if not decades.

... Sustainability as an Organizing Principle for Transportation Agencies 21 Sustainability Tools and Methods -- Key Directions for Development A substantial body of knowledge and opinion has been growing in the last few years on sustainability performance measures and assessment/rating systems that address one or more of the three sustainability bottom lines addressed throughout this report. At the level of transportation support for societal TBL and generational equity, models for the contributions of transportation investments and returns on TBL are easier concepts to visualize but challenging to develop and implement with current data and available algorithms.

... 22 Sustainability as an Organizing Principle for Transportation Agencies decisions with confidence. Major technological and scientific advances are envisioned in four critical areas: • Credibly supported and clearly understandable public information and measures to inform the public on TBL conditions and expectations -- possibly including an authoritative quality-of-life index that incorporates the three bottom lines.
