North Dakota consistently experiences a relatively high level of crashes and injuries on rural roads, considering lane miles and vehicle miles traveled. Approximately 55% of the state's travel, in vehicle-miles, takes place on rural roads. North Dakota fatal crash reports from 2003 to 2007 show that 89% of serious injuries, including fatal and disabling injuries, occurred on rural roads. The state must understand the effectiveness of safety interventions. The overall goal of this project was to measure effectiveness of alternative levels of intervention designed to heighten awareness and safety on rural roads. A multi-county case study was designed to include sustained and multifaceted safety interventions. Two counties were selected to be included in a designated traffic corridor where safety interventions would occur. Another county was used as the control case. Metrics used to measure effectiveness were a multi-phase driver survey, direct seat belt observations (pre-intervention, mid-intervevntion and post-intervention) and county-level crash/citation data. Results indicate had little effect overall on seat belt use in the targeted counties. |
