This paper proposes a new mobility equity metric and a routing framework for multi-modal transportation systems to improve fairness, accessibility, and efficiency in urban mobility networks.

Contribution

It introduces the Mobility Equity Metric (MEM) and integrates it into a system planner to optimize demand distribution for equitable transportation.

Findings

Enhanced accessibility and fairness in transportation networks

Improved efficiency in travel time distribution

System planner achieves socially optimal mobility

Abstract

In this paper, we introduce a metric to evaluate the equity in mobility and a routing framework to enhance the metric within multi-modal intelligent transportation systems. The mobility equity metric (MEM) simultaneously accounts for service accessibility and transportation costs to quantify the equity and fairness in a transportation network. Finally, we develop a system planner integrated with MEM that aims to distribute travel demand for the transportation network, resulting in a socially optimal mobility system. Our framework results in a transportation network that is efficient in terms of travel time, improves accessibility, and ensures equity in transportation.
