This study examined the impacts of ARTIMIS (Advanced Regional Traffic Interactive Management and Information System) in metropolitan areas of Northern Kentucky and Cincinnati, Ohio. As of 1999, ARTIMIS consisted of closed circuit TV cameras (CCTV), portable dynamic message signs (DMS), highway advisory radio (HAR), freeway and ramp reference markers, freeway service patrols, time-saving incident investigation equipment, and advanced traveler advisory telephone services. In February and April of 2000, two focus groups of area travelers were interviewed and 375 telephone surveys were conducted.

FINDINGS

Modeling efforts were conducted to quantify the impacts of ARTIMIS. Since baseline data were limited, the Federal Highway Administration (FHWA) ITS Deployment Analysis System (IDAS) was used.

Estimates indicated hydrocarbon emissions were reduced by 3.8 percent during the AM peak period, and 3.6 percent during the PM peak period. Carbon monoxide emissions were reduced by 3.8 percent during the AM peak period, and 3.6 percent during the PM peak period.. Nitrogen oxides emissions were reduced by 4.7 percent during the AM peak period, and 4.5 percent during the PM peak period.
