This document describes an extensible architecture for an intelligent navigation system that can use both radio-based and web-based traffic message channels. It discusses key terms like extensible architecture and intelligent navigation systems. It then provides details on a Continental CTP demonstrator project, comparing radio-based vs. web-based TMC, how the system works with multiple information providers, its software architecture using class diagrams, and system dynamics using sequence diagrams. The presentation aims to explain the project and gather feedback through a question and answer section.

Ciprian Rosu / Extendable Architecture for Intelligent Navigation Systems / October 16th , 2010 Extensible Arhitecture (1/1) In systems architecture, extensibility means the system is designed to include hooks and mechanisms for expanding/enhancing the system with new capabilities without having to make major changes to the system infrastructure. Extensibility can also mean that a software system's behavior is modifiable at runtime, without recompiling or changing the original source code. For example, a software system may have a public Application Programming Interface that allows its behavior to be extended or modified by people who don't have access to the original source code.

Ciprian Rosu / Extendable Architecture for Intelligent Navigation Systems / October 16th , 2010 Intelligent navigation system (2/3) What is an intelligent navigation system? The main improvement that basically makes a navigation system intelligent is the ability to acquire input and react to the changes in the environment. That means that the car's navigation system is not an inert, closed system anymore but an open, interconnected environment. What that means is that the system uses the info received for a better/quicker transparent automatic reaction. The car does what needs to be done quicker and more accurate.

Ciprian Rosu / Extendable Architecture for Intelligent Navigation Systems / October 16th , 2010 Traffic Message Channel (TMC) – Radio Protocol vs. Web based TMC (1/4) For every TMC message, additional information is embedded and used by the receiver (Navigation System). Just a few entries for that additional information are: length and duration, additional delay included, other advices for that specific TMC event... The navigation system that is capable to use TMC events uses this kind of information for route calculation, car tuning and car settings changes to adapt to the new environment conditions. Traffic Message Channel (TMC) is a standardized technology for delivering traffic and travel information to drivers. The info generally coded in radio transmissions can vary from weather conditions, accident or other blockage / delay on route to more complex traffic flow display.
Ciprian Rosu / Extendable Architecture for Intelligent Navigation Systems / October 16th , 2010 Traffic Message Channel (TMC) – Radio Protocol vs. Web based TMC (2/4) It's digitally coded using the FM-RDS system on conventional FM radio broadcasts. Usually each traffic incident is sent as a TMC message (also a more complex multigroup TMC events exists). This information is centered and then sent to radio stations that can transmit them. The info for every TMC event is coded on sender side and decoded on receiver side. TMCs are not supported in Romania for the moment. The present...Radio protocol
