CALYPSO is an interoperable electronic ticketing standard open to multi-application environments. It was developed by a group of European partners from the cities of Brussels, Constance, Lisbon, Paris and Venice.

CALYPSO provides the basis for a new service relationship with clients: facilitating access to networks, customizing travel cards and complementary services, diversifying sales outlets, and managing client databases.

The Co-Driver Alert project has successfully developed and demonstrated end-to-end
operability of an after market fit in-vehicle hazard alert system suitable for future deployment
in the UK. The concept of the Co-Driver Alert system is to provide increased driver
awareness to both static and dynamic hazards. This paper presents the project objectives, the
technical challenges faced during the development phase, and provides a description of the
systems architecture.

Although there has been considerable research on in-vehicle navigation systems, many safety and usability problems re-occur in system after system, even in systems that have been subjected to some sort of safety or human factors evaluation. This paper describes those problems and a test protocol to identify them.

The test protocol, developed as part of the process of evaluating the four systems, consists of two parts. The first part concentrates on the control layout, destination entry, and other tasks performed while the vehicle is parked. The second part concentrates on the route guidance while the vehicle is in motion. Both parts of the protocol rely on verifying compliance with human factors principles as determined by experts (heuristic evaluation) as well as data from carefully chosen test subjects using the system.

This paper reports on traveler (primarily commuter) perception of commercial radio traffic information. Data includes opinions expressed by participants in two efforts undertaken by the Michigan Department of Transportation (the DIRECT Operational Test and the Southeast Michigan ITS Expansion Evaluation). In both instances, participants were selected because they travel the expressway system in the Detroit Metropolitan area. The primary objective of the paper is to suggest ways in which commercial radio traffic information can be improved upon. The paper is divided into seven sections: data sources, study participants, participant use of commercial radio traffic information, subject rating of the performance of commercial radio traffic information, subject rating of the benefit of using commercial radio traffic information, subject suggestions of ways to improve the system under consideration, and implications for new information systems.

At the outset of the study, some members of the evaluation team thought that some form of new information service could potentially supplant or supersede commercial radio as a source of traffic information. Contrary to this notion, the study revealed that drivers very much appreciate and rely on commercial radio as a source of traffic information. Nevertheless, drivers do find some fault with commercial radio-based traffic information and have suggested a variety of ways to improve the usefulness of this information. The observations herein lead to a conclusion that a personalized route-specific interrupt or “push” system could be a valuable and readily accepted complement to commercial radio traffic information.

Floating car- and loop detector-based methods are two different methods that are
most frequently employed to collect travel time delay information across a freeway network.
More often than not, these two methods are jointly used to achieve the necessary freeway
network coverage, because of either the high labor costs of the floating car-based method or the
dependence of the availability of sufficient freeway network instrumentation of the loop
detector-based method. For example, both floating car- and loop detector-based methods are
implemented in the Highway Congestion Monitoring Program in the California Department of
Transportation. This situation makes it necessary to evaluate the compatibility in terms of
estimation accuracy between these two different data collection methods. In this paper, the
compatibility between these two methods was empirically evaluated. Corresponding delay
information estimated using both methods from 37 freeway segments in the Greater Sacramento
Area were collected and analyzed. It was found that the loop detector-based method is able to
estimate very similar delay to that as estimated by the floating car-based method, as long as the
later is enhanced by the real time loop-detector measured traffic flow information. The average
difference is less than six percent (6%) when delay is defined using a reference speed of 60 mph
or higher. It was also found that a one-mile spacing of loop detectors and 15-minute floating car
interval were sufficient to achieve such compatibility. This research supported that loop
detector-based method might be a more cost-effective choice for travel time delay data
collection if the freeway system is sufficiently instrumented.
