BASIC ISSUES IN EVALUATION The basic concept of an evaluation is simple and straightforward, but the actual process itself can be complex and involved. A transportation project is usually proposed because of a perceived problem or need. For example, a project to improve safety at a railroad grade crossing may be based on citizen complaints about accidents or time delays at the crossing site. In most instances, there are many ways to solve the problem, and each solution or alternative will result in a unique outcome in terms of project cost and results. In the railroad grade crossing example, one solution would be to install gates and flashing lights; another solution would be to construct a gradeseparated overpass. These two solutions are quite different in terms of their costs and effectiveness. The first solution will be less costly than the second, but it also will be less effective in reducing accidents and delays.
