Economic Evaluation

Economic evaluation is an important part of any public works planning process. For roundabout applications, economic evaluation becomes important when comparing roundabouts against other forms of intersections and traffic control, such as comparing a roundabout with a signalized intersection.

The most appropriate method for evaluating public works projects of this type is usually the benefit-cost analysis method. The following sections discuss this method as it typically applies to roundabout evaluation, although it can be generalized for most transportation projects.
