An open architecture for RTI applications

There is now a significant effort to apply electronic engineering, information technology and telecommunications to develop alternative approaches to improve the overall efficiency of the vehicle, its driver and passengers. This is a very new market with little hard commercial evidence of the demand for the various services that could be provided. The initial systems are addressing specific requirements (e.g. road tolls) and engineered for the minimum cost to achieve a specific function. The applications are tightly coupled to the chosen communications system. Several incompatible implementations of the same functionality emerge. However, as the number of services available increases the user may want access to several such services packaged into a single terminal
