Comprehensive travel information is a critical factor in tackling traffic congestion in
the U.S. and other countries, where bottlenecked roads and extraordinary delays often
approach crisis conditions. The goal of this paper is to illustrate how a consortium
approach to the collection and processing of traffic impact data, which integrates and
coordinates existing, independent data systems and delivery platforms, can improve
both information and communications to private and commercial drivers as well as
public agencies and yield a range of benefits, including more efficient travel,
enhanced road safety, lower pollution and fuel conservation.

In a multimodal travel information system, a wide spectre of actors, information elements and
services co-exist. When developing such a system some of the interoperability issues one has
to deal with are that the terminology used to describe the information and the semantic of the
information elements must be consistent both within and across all involved transport modes.
Furthermore, the system must be able to handle different kinds of back-end technologies and
formats. This technical paper reports on how the national framework architecture for
multimodal transport, ARKTRANS, and a Model Driven Architecture approach are applied in
combination to satisfy these prerequisites and to develop a set of multimodal travel
information services to be used as input to a national multimodal travel planner in Norway.

Traffic Scotland has been providing real-time information on the Scottish trunk road network
since 1999. The service has been continually developing and improving to meet the demands
and needs of the public, network managers and stakeholders. Traffic Scotland has undergone
a number of significant enhancements. These have ranged from performance upgrades to
provide improved service and to ensure maximum availability and accessibility in times of
high demand; functionality developments to include journey time, traveller emission and
public transport information; expansion of the network coverage allowing access to more
CCTV images; inclusion of greater event specific information; user tailored data available
through a range of media; and the adoption of DATEX2.

The potential to create innovative information services and applications, such as real-time
traveller information for a multi-modal journey for any given destination, or combination of
destinations, has never been greater. A facility or forum that could provide an experimental
environment for developing such services, an "information incubator", could encourage wider
experimentation with data and help persuade the users and owners of information to
collaborate and undertake further innovative projects. Using the scenario of providing realtime
traveller information for a multi-modal journey for a given destination, or combination
of destinations and/or activities, this work aims to demonstrate how a facility or forum could
be developed and provide such an environment. Notably, this work has been successfully
completed within a few months, which in itself is a significant feature of the challenge.

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.
