C H A P T E R 2 MethodologyChoice of Decision-Support System The approach to developing decision-support aids for transportation professionals was developed with the following issues in mind: • The capability limits of individual utility-locating technologies are poorly defined and may vary from one equipment manufacturer to another even within the same basic class of equipment. • There is little independent testing of utility-locating equipment and technologies to provide quantitative information to users or purchasers of the equipment and hence the principal information available on the range of application of different equipment comes from the manufacturers of that equipment.

This information includes performance indicators and other descriptive information, such as the following: • Whether the equipment is expected to find ferrous or nonferrous objects, or both; • Equipment applicability to four broad classes of soil type; • Minimum and maximum frequency of operation when applicable; • Effort or training required for data interpretation; • Relative cost indication; • Maximum depth of effectiveness anticipated; and• General application summary and more detailed method description.
