Database Analysis 73 In terms of uses relating specifically to the hazmat data in TIFA, over time, FMCSA has pub- lished data about the scope of hazmat crashes. In addition, FMCSA has requested data about fatal hazmat crashes to monitor trends. 4.5 Large Truck Crash Causation Study (LTCCS) LTCCS was designed as a one-time study to compile a comprehensive set of accident data for approximately 1,000 large truck accidents. The data compilation began in 2001 and was completed in 2003, although analysis of the data is still ongoing. 4.5.1 Database Description The LTCCS database is a series of tables that can be run in several relational databases. For pur- poses of this assessment, the tables were imported into the Microsoft Access database. The mas- ter table is the Crash file and contains 1,070 records representing the number of discrete accidents that were investigated. There were 107 of these accidents that were eliminated for one reason or another because they did not meet the analysis criteria. Thus, the LTCCS evaluates 963 discrete accidents. The next table is the CRASHASSESSMENT Table, containing a total of 2,284 records representing the data for the number of vehicles involved in the 1,070 accidents. Although all of these accidents involved at least one heavy truck, the second vehicle in many of the accidents was a passenger vehicle. Because the purpose of the study was to collect sufficient data to identify the causes of the accidents as well as to collect information on the drivers, vehicles, and environment present at the time of the accident, a lot of supporting information is provided. The dataset contains a total of 43 separate tables summarizing the many factors that, in total, represent a comprehensive set of data for each accident (see Table 4-21). Table 4-21 includes Table 4-21. LTCCS tabular structure arranged by category.
