The Crash Analysis and Reporting Unit is committed to providing the high- est quality crash data to customers. However because submittal of crash report forms is the responsibility of the individual driver, the Crash Analysis and Reporting Unit can not guarantee that all qualifying crashes are represented nor can assurances be made that all details pertaining to a single crash are accurate.

The first two parts provide data that show crash frequencies in relation to traffic volume and lineal length. Any comparison of crash data, either by count or formula, must recognize the vehicle miles involved. Failure to evaluate the data in this manner could lead to errors. Part I compares the Oregon to the nationwide traffic death rate. Traveled mileage death rates and population death rates are shown, as well as comparative rates by design types. Freeway and non- freeway data are presented by urban, suburban and rural subgroups. Part II presents five-year crash experience for each highway. Each state highway is divided into urban and rural sections, which are further subdivided for analysis. The start milepost, length, num- ber of crashes, average daily traffic, current crash rate, as well as the crash rate for the previous four years is shown for each sub section. Each section and highway is summarized. Part III contains summaries of this year's fatal crashes in Oregon. Since 1941, the Department of Transportation has summarized the records of all Oregon motor vehi- cle traffic crashes. This crash data has been made available to the public as well as government agencies. Since 1948, the Department has published traffic crash data. Current crash coding is guided by the "Manual on Classification of Motor Vehicle Traffic Accidents, 1989", published by the National Safety Council. Since 1998, Oregon law has required that any traffic crash on a public roadway resulting in a fatality, bodily injury or damage to one person’s property in excess of $1000 be reported. The Driver and Motor Vehicles Services Division is the repository for these reports. 4 PART 1 RESULTS OF ANALYSIS 5 F A C T S O F I N T E R E S T The State Highway System accounted for 20,320,715,923 vehicle miles of travel during 1999. This was an increase of 3.07 percent from the 1998 total of 19,716,008,889. The State Highway System had 222 fatal crashes during 1999. This represented a decrease of 24 percent from the 292 fatal crashes reported in 1998. The total number of persons killed in 1999 was 258, a decrease of 23 percent from the 1998 total of 335. The 1999 crash rate per million vehicle miles for non-freeway highway was 1.67. This was 4.77 times more than the total freeway crash rate of 0.35 for the same period. This difference between non-freeway and freeway crash rates indicates the greater safety of travel on freeways. An estimated 41,345 traffic deaths for the nation is a 0.3 percent decrease from the 1998 final figure of 41,471. Oregon, with a total of 413 killed in 1999, shows a 23.2 percent decrease from the 538 fatalities in 1998. 6 COMPARISON OF MOTOR VEHICLE DEATH RATES 1969 - 1999 Table I portrays annual motor vehicle traffic death rates on mileage and population bases from 1969 to 1999. The figures shown are estimates based on data from state traffic authorities, the National Center for Health Statistics, and the Federal Highway Administration.
