TL;DR: Sustainability of transportation systems is an important activity as evidenced by a growing number of initiatives around the world to define and measure sustainability in transportation planning and infrastructure provision as discussed by the authors. But there is no standard definition for transportation system sustainability, it is largely defined through impacts of the system on the economy, environment, and general social well-being.

TL;DR: In this paper, the authors reviewed methodologies that can be applied in sustainability assessment in transportation planning in order to shed light on the procedures being used to incorporate sustainability more effectively in the planning process.

TL;DR: In this paper, the authors developed four case studies to characterize some of the major transportation system sustainability issues in developed and developing economies and demonstrated that while transportation sustainability issues revolve around similar issues, the actual process of identifying and addressing pertinent issues to promote transportation systems sustainability may involve widely different priorities and constraints that should influence how standards are developed to promote successful movement toward sustainability in the international community.

TL;DR: In this article, a case study of the Atlanta metropolitan region is used to evaluate and discuss several performance measures and aggregates them into four parameters of sustainability: system effectiveness, environmental, economic, and social impacts, to enable visualization and assessment of tradeoffs and dominance for the competing alternatives.

TL;DR: In this paper, a composite sustainability index is introduced as a decision support tool for transportation policymaking, where the sustainability index considers multidimensional conflicting criteria in the transportation planning process.
