Academic journals publish studies conducted by researchers, such as college and university
faculty members, government employees, and private-sector employees including those of
industries and consulting firms. Some of this research may specifically focus on transport of
hazardous materials; other research may be more general and concern transportation and com-
modity movements. Access to academic journals may be by subscription, purchase of individual
articles, via Internet search engines, or through college and university libraries. There are many
academic journals, and those with information about hazmat transportation may include, but
are not limited to, the following:
· Hazardous Materials Control,
· International Journal of Mass Emergencies and Disasters,
· International Journal of Risk Analysis,
· Journal of Environmental Planning and Management,
· Journal of Hazardous Materials,
· Journal of Transportation Safety and Security,
· Transportation Research (there are several parts), and
· Transportation Research Record.
4.3 Electronic Databases and Reports
The project team can use existing electronic data sources to cover a wide variety of HMCFS
information areas. Table 4-1 lists electronic database and mapping sources, and Table 4-2 lists
electronic reports and other documents. The sources in these tables are maintained by federal
agencies. Mode applicability is indicated for highways, railways, pipelines, waterways, airways,
and other classifications. Check marks indicate that a source provides information about transport
networks, commodity movements, general system information (such as traffic levels, popula-
tion and critical facility locations), incidents, points of contact, and geographical and environ-
mental data. Both Tables 4-1 and 4-2 indicate the smallest jurisdictional size applicability by local,
regional/state, and national scale levels. General relevance to local hazmat transport is indicated

4.3.1 Transportation Networks
Identifying the routes (i.e., railways, roadways, waterways, pipelines, and airways) in a jurisdic-
tion that are capable of transporting hazardous materials is an important step in conducting an
HMCFS. Because not all routes are equally likely to carry hazardous materials, determining which
routes are most likely to carry hazmat transport establishes priorities for the HMCFS.
4.3.2 Commodity Movements
Commodity movement information covers what commodities are transported from location
to location. The Bureau of Transportation Statistics (BTS) and U.S. Census Bureau's Commodity
Flow Survey (CFS) is one of the most well known, comprehensive national sources of this data.
The U.S. Census Bureau also conducted the 2002 Vehicle Inventory and Use Survey (VIUS),
which includes information about hazardous material transport by different types of truck con-
figurations. The 2002 VIUS national-level data were compiled and summarized for this guide-
book (Appendix H). This information can be useful for a very general understanding of hazmat
transport in a community. It also can be used in conjunction with new data for truck counts.
Again, remember that much of the existing federal commodity movement information pub-
lished in these sources is not directly applicable to many local transportation network segments.
This is because the information is reported at the state level or higher, because the data are not
appropriately sampled for application at the local or regional levels, and/or the aggregation of
commodity groups limits identification of specific material hazards below class level.
4.3.3 System Information (Traffic)
Transportation system information covers performance of the transportation network (i.e.,
traffic levels on network segments). Although this information is not specific to commodity
movements, it can help prioritize network components for consideration in an HMCFS. Some
sources may be based on model estimates rather than observed traffic levels.
