Addressing Sustainability in Transportation Systems: Definitions, Indicators, and Metrics

Abstract

Addressing the 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. This paper reviews major initiatives in North America, Europe, and Oceania. The purpose is to characterize the emergent thinking on what constitutes transportation sustainability and how to measure it. While there is no standard definition for transportation system sustainability, it is largely being defined through impacts of the system on the economy, environment, and general social well-being; and measured by system effectiveness and efficiency, and the impacts of the system on the natural environment. Frameworks based on important causal relationships between infrastructure and the broader environment, infrastructure impacts on the economy, environment, and social well-being; and the relative influence of agencies over causal factors, are largely being used to develop and determine indicator systems for measuring sustainability in transportation systems. Process-based approaches involve community representatives and other stakeholders in planning and present opportunities to educate the public and influence collective behaviors. These frameworks can be used collectively to help agencies refine their visions as well as develop policies, planning procedures, and measurement and monitoring systems for achieving sustainable transportation systems.

Formation of service and resource stability conditions of urban public passenger transport

“…Розробка індикаторів та індексів сталої мобільнос-ті міського населення знаходиться у фокусі сучасних досліджень [9][10][11][12][13] і реалізується як правило шляхом виділення складу параметрів, що характеризують рівень транспортного обслуговування міського населення. Слід відмітити, що вибір параметрів сталості міського паса-жирського транспорту це складний процес, який потре-бує дослідження не лише внутрішнього його середовища, а передбачає формування її оцінки на основі обліку характеру і форми його міжрівневих зв'язків [1].…”

A Modified Method for Evaluating Sustainable Transport Solutions Based on AHP and Dempster–Shafer Evidence Theory

“…A broad range of methods and techniques have been proposed to assess the impact of transport solutions on city sustainability. Jeon and Amekudzi [17] set. In D-S theory, mathematically a basic probability assignment (BPA) is a mapping: 2 Θ → [0, 1] that satisfies ∑ A⊆Θ m(A) = 1, m(∅) = 0.…”

Dynamic Carpooling in Urban Areas: Design and Experimentation with a Multi-Objective Route Matching Algorith

“…The particular vehicles used for transport, the source of energy and the infrastructure used to implement the transport play a critical role for the evaluation of the social, environmental and climate impact [2]. Different alternative transport modes have been implemented for reducing air pollution, most of the time based on public transport services, where several options have been proposed and deployed according to the specific configurations of the cities' public transportation infrastructures, e.g., city buses, light rails, trains, subways, ferries.…”
