Description

An increased amount of driver assistance products are supplied by small and medium sized enterprises. An important premise for realizing these products is to establish a common database which provides required input data.

Abstract

Technological development opens up for increased communication between vehicles in motion and between vehicles and infrastructure. The CALM standard (Continuous Air Interface for Long and Medium range) will enable such communication. Thus, CALM could also contribute to increased traffic safety and efficiency by enabling increased dynamic traffic information to the drivers and to the driving assistance systems. This opens up for improvement of existing products and for developing new products. Real time updating of input data in products like navigation tools and ISA products (Intelligent Speed Adaptation) is a challenging task, which has not been solved yet. CALM will represent a significant technological shift toward solving this task, and utilizing results from the CVIS project is essential in obtaining this.

Developing and utilizing wireless communication solutions are essential in order to refine existing products and develop new ones. For the Norwegian situation, an additional essential factor is to develop a dynamic traffic information database, which is available for product and service suppliers. Product examples are: Driver training products, E-learning products, CALM products, Location based services, Intelligent Speed Adaptation products and Infotainment products.

A common information platform which integrates traffic data with information relevant for traffic safety will be developed in the Norwegian research project WiseCar. This platform should be available for both private and public partners in order to support product and service development and refinement. Several national databases will be of importance; databases which cover static information about the infrastructure, dynamic information about incidents, digital maps with point of interests, etc. Two main challenges will be to provide access to the information platform for SMEs and including data from numerous small information suppliers.

The requirement specification of the information system will be carried out during spring 2008. The first step is to define which data will be requested from the product and service providers, and which corresponding data sources could be utilized for establishing a database covering these data. It will be considered whether for instance navigation tools themselves can provide input data for the database.

The paper will present results from this research task, covering Data content, Data providers, Merging data sources, Data accessibility, Dynamic versus static data and Data quality

The WiseCar project will be carried out by a Norwegian consortium consisting of partners from industry, research institutes and public sector.
