ing service (if enabled by the user). Alternatively,
the voice message can be delivered as
an attached file to the e-mail account of the user
depending on the user profile.
Architecture
The architecture presented in Figure 3 is an
example of how “ITS Your Time” functionality
can be developed using open standards and common
components.
The architecture is divided into the following
layers for description:
• User terminals
• Carrier technologies
• Application context
• “ITS Your Time” framework
• Information-provider integration
• Telecom-operator integration
User Terminals
The terminals representing the targeted devices
for “ITS Your Time” are GSM/GPRS mobile
phones, PDAs using GPRS, built-in terminals
(in cars) and Internet connected PCs.
Carrier Technologies
GSM, GPRS, Internet and WLAN technologies
will be supported as a first approach, while other
technologies such as UMTS, DAB and DVB
may be included at a later stage.
Application Context
The application context will include different
applications, like HTTP, SMS, MMS, WAP
and voice messages.
ITS Your Time Framework
The framework could be based upon a J2EE
platform and contain the following basic services:
• User profile registration, including the usage
of Platform for Privacy Preferences Project
(P3P) [4];
• The “locator” service for tracking the user
position in the GSM network;
• The “lookup” service for finding relevant
information for the user from the information
providers;

• An adaptation layer that initiates the different
conversions, e.g. text-to-speech, content to
WAP, etc.;
• A geo-spatial database for keeping an online
and real-time picture of the information of
highest priority (accidents, major situations,
etc.);
• The interactive voice response and automated
speech recognition functions.
Information Provider Integration
“ITS Your Time” should use Internet standard
protocols for the integration of the information
providers, e.g. using XML.
Conclusions
As of today, there is no focal point for traffic
related information in Norway and the means of
both publishing and receiving dynamic traffic
information are poor. As the central mediator
of information to the road traveller “ITS Your
Time” will allow drivers, cars and content
providers to build a value network and exchange
information. This network will be able to carry
all relevant information to and from the road
users and be beneficial for the road user, the
content and service providers and society alike.
