As Intelligent Transportation Systems are deployed, adequate funding for operations and maintenance (O&M) quickly becomes a critical issue. Historically, Congestion Mitigation Air Quality (CMAQ) funds have been used as the catalyst both for project deployment and start-up operations. However, the challenge that most state DOTs face is identifying and securing long term sources of funds to meet O&M requirements. Advanced Traveler Information Systems (ATIS) projects can have significant O&M costs to DOTs.

The Rhode Island Department of Transportation (RIDOT) has recently implemented two ATIS projects that advance their goal of disseminating traveler information to the public: a cable traffic channel and website featuring live camera images. With a focus on the right technological fit to the states needs and agency resources, these projects have been implemented in an integrated, low cost, manner that provides a framework for future private sector partnerships. These projects have also provided a great deal of positive publicity for the Rhode Island ITS program.

ARKTRANS is the national framework architecture for multimodal intelligent transportation
systems (ITS) in Norway. This paper describes an action research approach where
ARKTRANS is improved through practical use in a project addressing multimodal travel
information services. The usability of ARKTRANS with respect to person transport, travel
information service and multimodality is assessed. An overview of the content of
ARKTRANS that supports the establishment of new and improved travel information services
is given: The roles played by the stakeholders involved; the functionality needed by these
roles; process descriptions showing interactions between the roles; information exchanged via
open services; and the technical implementation of these services.

This paper reports on recent developments brought about in the area of freeway travel time
measurement based on the innovative use of Bluetooth signatures in an automatic vehicle
identification setting. The concept of using Bluetooth signatures for travel time estimation along
a section of freeway is explained. Issues related to filtering raw matched data and accuracy of the resulting “ground-truth” are addressed. Capabilities and limitations of an existing adaptive
exponential smoothing methodology in extracting accurate travel time estimates in real-time are
examined.

This paper presents an algorithm to predict an individual’s real-time travel path and destination using
data from a Global Positioning System (GPS) enabled mobile phone. The algorithm uses spatiallyaware,
geometric representations of a user’s historical trip data in its comparisons thus eliminating the
need for taxing calculations. This technique also promotes scalability through the use of enterprise
spatial database systems. Multiple modes of transportation are supported since the algorithm does
not rely on road network information. This Path Prediction algorithm can enable a variety of services
such as real-time localized traffic incident reporting, location-based advertising, and live traffic
management.

The Regional Transportation Authority (RTA) of Chicago is investigating the feasibility of implementing real-time Parking Management Systems (PMS) for transit station applications in northeastern Illinois. This PMS study is part of a larger effort in the Gary-Chicago-Milwaukee (GCM) ITS Corridor toward development of a Regional Multi-Modal Traveler Information System. The work is being performed in close coordination with the three regional transit service boards (Chicago Transit Authority [CTA], Metra commuter rail, Pace suburban bus).

The PMS study includes an implementation plan that defines initial demonstration project locations, and is establishing both a system architecture and regional standards for design and configuration of real-time parking management components. These standards would assure common types of parking information displays at transit park-and-ride facilities in the Chicago area, regardless of service provider. The uniform standards would facilitate leveraging of capital and maintenance costs between different service boards, thus reducing overall program costs.

Study activities include:

• Needs assessment from both operator and user perspectives
• Review of technologies
• Functional requirements definition
• Conceptual definition of PMS operational schemes and display types
• Implementation plan and identification of demonstration sites
• Standard specifications for system and displays

The study is being performed for the RTA by Wilbur Smith Associates, with subconsultants HNTB and TranSmart Technologies.
