Subsurface utilities, buried from inches to many feet below roadways and rights-of way, pose significant challenges because they are not visible and cannot be assessed through visual inspection. Their location, condition, ownership, and impact on cost and schedule must instead be determined through specialized investigation methods and stakeholder coordination. Utility data depiction is the primary means of communication, yet it is often inconsistent, with varying stakeholder expectations.

NCHRP Research Report 1180: Depicting Utility Facilities in Design Plans: A Guide, produced by TRB’s National Cooperative Highway Research Program, provides a set of guidelines for transportation agencies on depicting utility data from various sources. These guidelines support design decision-making, utility conflict identification and resolution, and consistent depiction practices. The scope includes both existing and proposed utility facilities. The guide is intended to support both 2-D and 3-D formats, recognizing that agencies vary in their access to and proficiency with different software tools.

The same project that developed NCHRP Research Report 1180 also produced NCHRP Web-Only Document 449: Developing a Guide to Depicting Utility Facilities in Design Plans. This companion document summarizes the research conducted to develop the guide.

For this report, new mobility services are defined as innovative transportation services that redefine how people and goods move within the existing transportation system. Examples include micromobility (shared bikes and scooters), car-sharing, ride-hailing, microtransit, and modern goods delivery services. Revenue measures applied to new mobility services can help agencies that own and manage the transportation system fund staff, technology improvements, and right-of-way modifications. Pricing strategies can also help manage demand for both the services themselves and the public spaces they use. Some new mobility services may merit subsidies because they advance community transportation goals. However, decision-makers are often unaware of the full range of revenue-related tools available to them.

NCHRP Research Report 1165: Revenue-Related Tools for New Mobility, produced by TRB’s National Cooperative Highway Research Program, includes a decision-making framework and examples of best practices to assist those who manage or fund surface transportation networks as they explore ways to subsidize, charge, or assess new mobility services. The report describes the framework for evaluating revenue-related tools for new mobility and explains how to apply the framework. The report also examines promising and innovative revenue models.
