How do you address equity and social justice in transportation demand?
Transportation demand is the amount and type of travel that people choose to do under certain conditions, such as cost, time, convenience, and accessibility. Transportation demand management (TDM) is a set of strategies and policies that aim to reduce the need for single-occupancy vehicle trips, encourage the use of alternative modes, and optimize the efficiency of the existing transportation system. However, TDM is not a neutral or objective process. It can have significant impacts on the distribution of benefits and burdens among different groups of people, especially those who are historically marginalized, disadvantaged, or discriminated against. Therefore, addressing equity and social justice in transportation demand is a crucial and ethical responsibility for transportation planners and practitioners. In this article, we will discuss some of the key concepts and approaches to do so.
