Title:

Rural Freeway Management During Snow Events: ITS Application

Abstract:

Based upon visibility, road surface conditions, and capacity of towns to accommodate motorists; Mn/DOT and law enforcement personnel activate warning sign, lower (or swing) gate arm, and activate gate lights to prohibit access to rural interstate freeways. Law enforcement personnel are positioned at gate location during closing and reopening. Systematic and well-coordinated plan for closing and reopening has reduced delay (mobility), accident frequency (safety), and lowered Mn/DOT costs to clear and reopen by 15% (productivity). Significant time savings result in less overtime pay. Future plans include the addition of fixed and portable VMS, CCTV cameras, and an electronic map.
