摘要：	Historically, the most convenient strategy for the transportation designer was to ignore the utilities during design and make them relocate if they end up conflicting with the highway construction footprint. As such, highway projects are often designed with little or no consideration of utilities. Utilities are routinely relocated, often at great expense and often unnecessarily. The most difficult option for the designer is to accomplish the transportation improvement mission while leaving all of the existing utilities in place. Sometimes this is impossible. Somewhere between the extremes of relocating all the utilities and leaving all the utilities in place is a workable compromise that meets the highway construction scope and mission, while minimizing impacts to utility facilities. If this compromise can be found, there can be substantial savings in utility relocation costs and impacts, as well as overall savings to the project budget and timeline. This study explores current practices in use by transportation agencies for consideration of utilities during the project development process, including where in the process the utility impacts are assessed and relocation decisions are made; what policies, regulations, manuals, and guidelines are used; and how design decisions are influenced by utilities. The study includes both below-ground and above-ground utilities. This study does not include the many related aspects of the practice of utility coordination; those details can be found in the 2009 SHRP 2 report Integrating the Priorities of Transportation Agencies and Utility Companies. / Supplementary Notes: See also PB2010-106514.
