Cost–Benefit Analysis of Added Cycling Facilities

Li, Mingxin / Faghri, Ardeshir

Cycling is well acknowledged as one of the most energy-efficient and healthy modes of transport; walking follows closely. Many approaches and models have been devoted to finding ways to increase the proportion of bicycle trips. However, significant uncertainty exists about the level and effectiveness of added cycling facilities. Few studies have conducted a detailed cost–benefit analysis (CBA) of added cycling facilities. To fill this knowledge gap, a comprehensive method is proposed for estimating the most important benefit components and expenses associated with the installation of bicycle facilities and gaining a better understanding of the strategies used to identify their effect. The general CBA framework that is developed could be used as a traffic planning tool for relieving congestion and improving bicycle networks. The tool can generate preliminary cost estimates quickly at an early planning stage. The focus is primarily on cycling, but the findings may be easily applied to other active modes of transport such as walking and scooter use. A case study in the state of Delaware demonstrates how the proposed approaches can be used to assess the impacts of road investment projects.
