Travel time information effects drivers’ route choice behavior, and is regarded as one of the
effective measures to ease traffic congestion. A questionnaire survey on travel time
information was conducted at Service Areas (SA) and Parking Areas (PA) on the expressways
in Japan. The questionnaire mainly consisted of questions on the consciousness and needs for
travel time information and their route choice behavior with/without the information. It
reveals that approximately 80% of drivers accept ±10 minutes error of travel times. When an
increase or a decrease arrow was added to travel time information under the questionnaire, it
had a considerable influence on their route choice behavior. As a result, it was clarified that
the display of the arrow on travel time information had possibility to relieve traffic congestion
effectively.

This paper describes the application of systems engineering (SE) to a major innovative
transportation project in the San Francisco Bay Area, the Interstate 80 (I-80) Integrated
Corridor Mobility (ICM) Project. In addition to being one of the first applications of Active
Traffic Management (ATM) to a freeway corridor in the U.S.A., it is also one of the first
detailed applications of formal SE processes to a major highway traffic management project
in the U.S.A.

The Advanced Regional Traffic Interactive Management and Information System (ARTIMIS) is a regional traffic management system provided by the Kentucky Transportation Cabinet (KYTC), Ohio Department of Transportation (ODOT), Federal Highway  Administration (FHWA), Ohio-Kentucky-Indiana (OKI) Regional Council of Governments, and the City of Cincinnati. ARTIMIS has two major functions, specifically, Advanced Traffic Management Systems (ATMS) and Advanced Traveler Information Systems (ATIS). The ATIS service, known as SmarTraveler, is but one component of the ATIS function and is hereinafter referred to as the ARTIMIS Traveler Advisory Telephone Service or ARTIMIS TATS.

The following are the overall objectives that this research project was created to meet:

• to assess the overall satisfaction and effectiveness of ARTIMIS TATS;

• to determine the general awareness of ARTIMIS TATS in the regional coverage area;

• to determine the prevalence and preference of accessing the service through the use of

a N11 dialing code, such as 211, versus a seven-digit number; and

• to determine the influence of traveler information on travel behavior.

In order to accomplish these objectives, two surveys were designed and undertaken.

ARTIMIS TATS users were invited to participate in the first survey, by intercepting their calls into the system. The second survey, an awareness survey, was designed as a random-digit dial survey for people in the ARTIMIS coverage area. The results relating to user satisfaction and the effect the system has on travel behavior can be found in a forthcoming paper in Transportation Research Record.

This paper reports on the performance of advanced traveler information systems (ATIS)during the 2002 Salt Lake CityWinter Olympic Games. This was the first Olympics in the United States with an established Intelligent Transportation System (ITS) deployment in full operation, and the Salt Lake City ITS installation was among the most comprehensive in the nation. This paper presents excerpts from a larger study, commissioned by Utah Department of Transportation (UDOT) and the Federal Highway Administration. The purpose of that larger study was to document and assess the performance of the UDOT advanced traffic management system (ATMS) and advanced traveler information system (ATIS) during the Olympic Games. An additional purpose was to document and assess the results of the Travel Demand Management program created and implemented for the Olympic Games. This paper presents some of the traveler information findings from that larger study, specifically regarding the CommuterLink Website and the 5-1-1 Telephone Service.
