Using GIS in Denmark for traffic planning and decision support

GIs, since the handling of data is more rational and the presentation and quality control of results can be done more easily. For this reason, traffic modelling is maybe the field in traffic planning that has made most use of GIs, e.g. [Gallimore et al., 1991, Hartgen et al., 1992 and Simkowitz, 19901 as well as many other of the referencesGet price
