Integrated interoperable emergency communication equipment means equipment that supports an interoperable emergency communications system.
Interoperable emergency communications system means a network of hardware and software that allows emergency response providers and relevant Federal, State, and local government agencies to communicate with each other as necessary through a dedicated public safety network utilizing information technology systems and radio communications systems, and to exchange voice, data, or video with one another on demand, in real time, as necessary.
Operational improvements means a capital improvement for installation of traffic surveillance and control equipment; computerized signal systems; motorist information systems; integrated traffic control systems; incident management programs; transportation demand management facilities, strategies, and programs; and such other capital improvements to public roads as the Secretary may designate by regulation.

Public road means any highway, road, or street under the jurisdiction of and maintained by a public authority and open to public travel.
Road Safety Audit means a formal safety performance examination of an existing or future road or intersection by an independent multidisciplinary audit team.
