Goal of spotlights. TN/GTF • Get the modelling community in Europe (in the World) Goal of spotlights. TN/GTF • Get the modelling community in Europe (in the World) to “establish the necessity of a common exchange format for transportation models” suggestion of a conceptual view as a basis • contact modellers / software providers • discuss GTF Goal means for discussion: GTF-CM • Email spotlights@mkm. de discuss GTF-CM: • Forum gtf. mkm. de • Mailinglist gtf@lists. mkm. de Outcome: 11 th October 2001 Agreement & Common Understanding Barcelona MKmetric

Overview of requirements Supporting Model Communication 1. Model requirements: GTF = Generalised Transportation data Overview of requirements Supporting Model Communication 1. Model requirements: GTF = Generalised Transportation data Format - EDI format to exchange transportation modelling information - not to impose formats or contents constraints on modellers exchanging data - not specifically for GIS GTF specifies building blocks (entities) GTF is a general structure of the information transport models use Principles: - not too many basic building blocks (generic entities) - generalised enough for (mainly) modelling information and (also) other information • GTF = Exchange of Data (homogeneous & generic) 11 th October 2001 Barcelona MKmetric
