AN OBJECT-ORIENTED APPROACH TO TRANSPORT MODELING - SOFTWARE-DEVELOPMENT TO CALCULATE ROAD TRAFFIC NOISE

A framework for developing object-oriented software in transport model ling in proposed and demonstrated with the implementation of the calcu lation of road traffic noise (CORTN). Major tasks in the life cycle of an object-oriented development process are identified, and illustrate d with the implementation of TRANSOOP - a software library containing 33,000 lines of C++ programming code. Software re-use from this librar y to produce a object-oriented noise program is compared with conventi onal computer programming shows that almost 90 per cent of the lines o f code were drawn from TRANSOOP. Advantages of the object-oriented app roach are discussed.
