Demand And/oR Equity (DARE) method for planning bike-sharing

Duran-Rodas, David / Wright, Benjamin / Pereira, Francisco C. / Wulfhorst, Gebhard

Highlights • The DARE method enables the inclusion of equity in the bike share planning process. • DARE builds different scenarios for balancing ridership and equity in the planning process. • Stations are distributed based on a ranking index that weights equity and demand. • Disadvantaged areas are prioritized when equity is preferred over ridership. • Four different algorithms for allocating stations provide scenarios favoring coverage or density.

Abstract Most bike-sharing systems in cities aim to maximize demand, an approach that tends to inadvertently favor wealthier neighborhoods. Therefore, we developed a heuristic and data-mining-based method to weigh both Demand And/oR Equity (DARE) in the station distribution and allocation process of planning bike-sharing. Equity is measured using a deprivation index and the potential demand is estimated using structural equation models via the built and social environment. The DARE method was applied first to the BSS service area in Munich, Germany, and then, to the area surrounding Munich, demonstrating the method’s transferability. Incorporating equity resulted in disadvantaged areas being better served by bike-sharing stations while favoring ridership (demand) tended to cluster stations in the wealthier city center. This method allows decision-makers to build scenarios for allocating infrastructure based on their desired fairness criterion, and can also be applied to other shared modes or public transport.
