| Transportation enforcement agencies have typically relied on the number of citations issued during a given time-period to measure the effectiveness of current enforcement levels. Although citations demonstrate the extent of enforcement, there is an absence of meaningful data on the impact of these activities on the number of vehicular crashes. In an effort to improve safety and evaluate optimal levels of investment in trooper patrols, a new methodology was produced to correlate information on trooper vehicle presence with data on crash occurrences.;Using information recorded by sensors installed on State of Alaska trooper vehicles, and crash reports gathered from the Alaska State Troopers (AST) and Alaska Department of Transportation and Public Facilities (DOT&PF;), large-scale data sets were established through geospatial data collection for five selected corridors in Alaska. After data filtration and organization, statistical analyses revealed particular characteristics of the collected data. In addition, the research successfully verified that geospatial data from trooper vehicles, along with crash data, might offer valuable correlations for state agencies to monitor in the future. Analyses also revealed that inclusion of additional independent contributing factors and at least another 18 months of data collection are needed to achieve statistical significance for meaningful conclusions. |
