Abstract (eng): | This Master's thesis has been written partly on my own initiative, partly thanks to a scholarship granted by the Nordic Road Association. This work is a research on how the large national road databases in the Nordic countries have been defined and implemented. Information about the traffic routes in different countries is becoming more and more important, when the mobility grows and the driving routes must be maximally optimized, for example in respect to time, economy, environment and safety. The Nordic countries concerned here are Finland, Sweden, Norway and Denmark. The national road databases in the Nordic countries are presented and analyzed from a technical point of view. The routines of the systems are also touched, even if they aren't in focus. The most integral matters for a road database are the road definition, the coordinate system, the data model, the linear reference system, the properties of the geometry and the topology and also the features that can be given to the roads. The issues presented vary to some extent from one database to another, according to what has been defined with reference to the road database in question and what generally can he considered as relevant. In this thesis, the main aspects found considering the Nordic road databases will be summarized. Above all, it's a matter of those similarities and differences that most likely will have a great impact on the future internationalizing process. This process contains a suitable Nordic standard for road data. Here, a first step in this development towards a road database standard is taken by recommending proper common outlines for the future. The suggestions how the Nordic countries could approach each other are technical. No comments are given on which organisation should carry out the harmonizing process or where economical resources could be found. The Nordic road databases are essentially different with respect to purpose of use. Some are implemented for traffic telematics, which means mobility using as much existing information potential as possible to find the most favourable driving routes. Others are intended for a much wider use in road and traffic issues. The main focus in this report is mobility. Road data is here analyzed depending on to which extent navigational purposes can benefit it, although its original purposes might be others. |
