  • Coordinated, Subsidized Public Transportation Service in Rural Areas

    Currently, many federal/state/local agencies are providing diverse public transportation service at the historically slow-growth rural areas. The integration of these available rural transit services can be greatly enhanced with the automated demand-responsive transits, and coordinated transit service equipped with the Intelligent Transportation System and Information Technology (ITS/IT) technologies. This paper discusses both the available ITS technologies and existing institution barriers that are essential to improve the quality of life at the rural communities.

  • Artimis Telephone Travel Information Service: Overall Public Awareness

    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.

  • Field Test Results of Various Unlicensed Wireless Technologies For Transmission of Live Video

    The Texas Department of Transportation is interested in determining what the best and most cost effective technology to use that provides last mile connectivity to their TranStar Transportation Management System and can provide an easy way to bridge breaks in their fiber network that occur through accident or new construction. This TxDOT sponsored evaluation identified the most cost effective technology to use by using a proof of concept demonstration in a real world environment.This paper reports the results of the test and evaluation of the data and video wireless communications using the unlicensed 2.4GHz and 5.8 GHz frequency bands over a distance of 17.4 miles. Wireless telecommunication products that were tested ranged in price from $3,700 to $12,600. Two technologies were evaluated using live video transmitted at 30 frames per second and encoded to the MPEG2 standard. They were: • 2.4 GHz ISM Band using the IEEE 802.11b standard (2 Million bits per second (Mbps) to 11 Mbps data rates) • 5.8 GHz U-NII Band compatible with the IEEE 802.3 standard (10 Mbps to 430 Mbps data rates)

  • Skyline Products DMS Message Effectiveness Tool - Signs of Intelligence for Sucessful Communities

    This white paper, DMS Message Effectiveness Tool—Signs of Intelligence for Successful Communities, offers practical advice, case studies, and the Skyline Products DMS Message Effectiveness Tool to help agencies develop their policies regarding effective Dynamic Message Sign (DMS) usage. A key to effective advisories is displaying messages that are clear, concise, credible, and actionable—such advisories help the agency achieve the greatest results for its Intelligent Transportation System (ITS)environment.

    Specifically, the goal of this white paper is to be a reference tool for any DOT agency developing or tuning its policy on the use of DMS messages. Such a policy would provide guidelines for DMS managers and operators to relay clear, informative, and relevant messages. This is an important consideration, since motorists must be able to quickly comprehend the DMS advisory, filter the information as it relates to their situation, and take appropriate action. Of course, this all happens in a matter of seconds, while drivers speed along in complex traffic conditions and often in less-than-ideal weather conditions.

  • Cross Cultural Differences in Human Machine Interfaces of Driver Information Systems

    Driver-Information-Systems (DIS), telematics hardware, telecommunication and IT devices become more and more part of modern vehicles. Both, technology and users, press new devices into the cockpits. Driving still remains the main task, so the design of the human machine interface (HMI) has to be done carefully to avoid loss in safety due to driver distraction.

    A cross cultural usability study with existing automotive DIS supported any hypothesis on differences between users. A software tool used to produce application ready software for DIS directly out of the simulation was developed. The HMI components can easily be adapted to local market needs, without changing the major (functional) part of the program.
