This table provides a classification of strategies according to the expected time frame and relative cost for this emphasis area. In several cases, the implementation time will be dependent upon such factors as: the agency’s procedures, the length of roadway involved, the need for additional ROW, and the need to follow environmental impact processes. The range of costs may also vary for some of these strategies, due to many of the same factors. Placement in the table below is meant to reflect the most common expected application of the strategy.
