Overview

Background & Policy context

The dynamic behaviour of the linear reference system is one of the particular characteristics of a road information system. Because this linear reference system can change spatially and temporally, a description method of a road information system must have the ability not only to define the static structure but also to describe the dynamic behaviour of the objects of a road. The object oriented
method offers this ability to model the structural and behavioural aspects in a combined and integrated way. The research needs are to define conventions allowing an object oriented modelling of a road information system.

Objectives

The main goal of this research is to analyse process normalization methods and to apply these to the main management processes of the road information system.

The project furnishes the following elements:

  • Description management processes for the information system
  • Analysis of object oriented approaches and their representation types (notation)
  • Choice of a method and a notation
  • Feasibility study by applying the method and notation to some examples of processes
  • Analysis of the results relative to the VSS normalisation and relative to the communication needed for the evolution of the information system

Results

For all objects of a road information system, as far as these are thematically defined in the current
standards, a class model with a complete specification of all structural characteristics is worked out.
The class model is modelled with elements of the UML. Furthermore the same model is also described in INTERLIS so that this model can also be used for a transfer of road data.

It can be concluded that there is only a limited interoperability between UML and INTERLIS. There
are no official rules for the transformation between the two modelling languages. Therefore some
transformation rules are defined as part of a UML profile for INTERLIS. With these rules an
automatic transformation from a UML class model into a INTERLIS class model is possible.
The developed class model reflects all actual knowledge of road objects. That is, this model reflects
this actual knowledge, how in a road information system the appropriate objects should be described.

From this, measures can be determined and pointed out to be applied on the existing data catalogue
standards (SN640940 ff), so that an actualisation of these standards can be started.

The elaborated results can be applied and reused in the development and operation of road information systems. They form a basis for future activities which are based on conceptual, object oriented structures.
