| 摘要： | The purpose of this study was to identify, through a literature review, the potential safety benefits of implementing various ITS technologies through Virginia's Smart Travel Program. This study was requested by the ITS Section of the Virginia Department of Transportation to document what is believed to be an underestimated benefit of ITS: safety. Several Advanced Traffic Management Systems Technologies improve safety, primarily through reducing congestion. In general, this reduces crash risk, particularly for multivehicle crashes. Advanced Traveler Information Systems (ATIS) provide information to the public by such means as the broadcast media, cable television, highway advisory radio, and the Internet. Although no studies document an impact, a simulation study showed that such a system has the potential to reduce crash risk. Commercial Vehicle Operations (CVO) applications have the potential to reduce the risk of fatalities and serious injuries. CVO are generally geared to improving the efficiency of safety inspections and reducing inconvenience to motor carriers that are not in violation. Because of greater efficiency, more hazardous vehicles and drivers can be removed from service. |
