Book Description
Traffic crash statistics indicate that the eight southeastern states (Alabama, Mississippi, Georgia, Florida, South Carolina, North Carolina, Tennessee, and Kentucky) consistently have higher numbers and rates of fatal motor vehicle crashes than the national averages. Under the auspices of the Federal Highway Administration, these southeastern states are conducting a pooled fund study to investigate the overrepresentation of crashes in the region. This study is being coordinated by the Georgia Institute of Technology (Georgia Tech), with universities in each of the other states serving in a supporting role. This report addresses South Carolina's portion of the study, as performed by a Clemson University research team. The principal objectives of this research were to obtain for the South Carolina Department of Transportation a set of data records for randomly selected fatal crashes on rural South Carolina two-lane roads, evaluate these data, and ascertain how the safety of these roads might be improved by specific crash countermeasures. A comprehensive data set was collected for 157 randomly selected fatal crashes.

Book Description
This report examines the roadway, crash, vehicle, individual and environmental factors that are associated with fatal and serious injury crashes in North Carolina between 1993 and 1997. The initial analysis identifies road classifications, geographic characteristics, and time trends related to severe crashes using Highway Safety Information Systems (HSIS) segment and crash data. HSIS system highways in North Carolina included the state primary and major secondary routes. Non-HSIS roads include local streets and minor secondary streets. Both HSIS and non-HSIS data are used in the more detailed section of the study to analyze the severe crash factors on all HSIS highways, two-lane urban HSIS highways, two-lane rural HSIS highways, urban non-HSIS routes and rural non-HSIS routes. In this report, a test of the standard error of a binomial proportion is used to find the statistical significance of the roadway, crash, vehicle, individual and environmental factors related to severe crashes. The initial analysis shows that urban and rural two-lane roads are associated with the highest crash severity, mountain counties have the highest proportion of severe crashes and crash severity remained stable for some of the most severe crash types. Factors associated with significantly high crash severity on all roadway types include curve, run-off-road, utility pole, tree, head-on, pedestrian, bicycle, darkness and alcohol use. The final section of the report recommends countermeasures that can be used to reduce the incidence of fatal and serious injury crashes associated with these factors.

Crash Causal Factors and Countermeasures for High-risk Locations on Multilane Primary Highways in Virginia

Book Description
In 2004, a total of 95,020 vehicle crashes occurred on highways under the jurisdiction of the Virginia Department of Transportation (VDOT). Of these, 39,847 crashes occurred on primary highways, and 345 of these were fatal crashes. VDOT's traffic engineers continue to place increasing emphasis on identifying causal factors for crashes to enhance the selection of appropriate and effective countermeasures. The purpose of this study was to identify causal factors and appropriate countermeasures for crashes occurring at high-risk locations on multilane primary highways from 2001 through 2006. These high-risk locations were identified by Fontaine and Reed (2006) in a VDOT safety corridor study. A total of 365 sites, 1 to 2 mi in length, were used in the study. The statewide sites were located on rural and urban highways with divided, undivided, and traversable medians, with about 40 sites per VDOT district. Crash data were extracted from police crash reports, and geometric data were collected through site visits. Operational data were collected using VDOT's resources. The analysis involved more than 34,000 crashes and was conducted using fault tree analysis and generalized linear modeling. The fault tree analysis was used to determine the critical fault path based on the probability of an event occurring. Individual fault trees were constructed for each collision type and for each highway classification. The generalized linear models were developed for different highway classifications: urban divided, urban undivided, urban traversable (central lanes that can be used for left turns in both directions), and rural divided highways. Models were developed for rear-end crashes and total crashes, and separate models were developed for injury crashes, property damage only (PDO) crashes, and injury + PDO crashes. Appropriate potential countermeasures were then identified based on the significant causal factors identified in the models. The results indicated that rear-end crashes were the predominant type of crash, representing 56% of all PDO crashes on urban divided highways and 37% of all PDO crashes on rural divided highways. Implementing the recommended countermeasures for total, rear-end, and angle crashes for different assumed levels of rehabilitation is expected to result in a crash reduction of up to about 40% depending on the site and level of rehabilitation undertaken. A benefit/cost analysis showed that the benefit/cost ratios were higher than 1 for all levels of countermeasure implementation.
