The Option Appraisal Tool is a tool to assist transport and urban planners to structurally compare different options for road space allocation through road design, taking into account the needs of all road users and a range of policy objectives. The tool has three independent modules that consider a political and technical assessment, a cost-benefit analysis and a multi-criteria analysis, besides the general inputs, such as performance indicators for the movement and place functions of the road and the economic, social, and environmental impacts. It is employed at the last stage of the road space reallocation to select the final road design.
