Supplemental Analyses of System Components
Chapters 23 through 27 delve more deeply into the
analyses developed in Chapters 2 through 10 to focus on particular components
of the Nation's highway and transit systems. Some of these analyses pull
together material scattered in other locations through the report; others
provide supplementary information not covered in the earlier chapters.
The five supplementary analysis chapters in this edition
of the report are:
- Chapter 23, Interstate System,
highlights the system characteristics, system conditions, operational
performance, and financing of the Interstate system. The chapter also
analyzes future investment requirements for the Interstate system. While
the rural and urban Interstates are identified in the functional class
tables in Chapters 2-10, this chapter provides additional details and
brings all Interstate-related information into a single location.
- Chapter 24, National Highway
System, is similar in scope and coverage to Chapter 23, but focuses
on the entire NHS, rather than simply its Interstate System component.
While some of the earlier chapters in the report include some NHS-related
data, most information pertaining to the NHS in this report is located
in this chapter.
- Chapter 25, NHS Freight Connectors,
includes an analysis of future investment requirements for these critical
links. Many of the physical and operating deficiencies of NHS connectors
are different in character than those of the mainline NHS; this special
analysis is intended to identify items beyond the scope of the general
NHS analysis contained in Chapter 24.
- Chapter 26, Highway-Rail Grade
Crossings, focuses on the delay-related costs imposed on highway
users. While grade crossings have traditionally been viewed as a safety
concern, they also can have a considerable impact on the operational
performance of highways.
- Chapter 27, Transit on
Federal Lands, identifies the future investment that would be required
to address growing demands for transit in these areas. This chapter
is provided as a complement to the highway-oriented section on Federal
Lands included in the 1999 C&P report.
