Simulation Models

TRM Engineering has built up over ten years of experience in the development of traffic simulation models employing the most tried and tested simulation software (Cube Voyager, Visum, Dinasym, Vissim, Syncrho, Sim Traffic, and Girabase).


This decade-plus of specific experience in the fields of Private and Public Transport simulation models at all levels of detail has enabled TRM Engineering to gain recognition among public and private operators (see CLIENT section) for the high levels of quality and communicativeness of its work.

The high number of models developed nationwide together with experienced gained allows the Company to count on not only a time-tested and efficient methodology but also on a sizeable data bank which allows it to model accurately and to tight deadlines across a range of territories ranging from large scale (national, regional and provincial) to the more localized (local council or limited areas there within).

This allows TRM Engineering to implement private traffic and public transportation simulation models, territorial IT systems right up to microsimulation models for analyzing small-scale traffic networks and specific road junctions.


The elevated level of professionalism and the continuous training and development of its technical staff, together with a direct relationship with distributors and manufacturers enable the maximum level of quality in the development of each model across all sizes of project.

The main area of TRM Engineering development can be divided into two branches: macroscopic and microscopic.

The MACROSCOPIC approach foresees the use of continuous models with an underlying law of correspondence between velocity and density and between flow and density.

The MICROSCOPIC approach does not take into consideration traffic flow in its entirety, but rather focuses its attention on individual vehicles and how they inter-react.

The developed models evaluate the propensity of those moving within the targeted area to use various forms of transport: modes of private transportation (car, motorbike, bicycle etc), modes of public transportation (bus, train, tram, subway etc) and on foot.

The concluding phase of a modeling study involves the analysis results, the evaluation of proposed solution and, whenever the analysis flags up potential critical aspects, the identification of solutions to be adopted.

Choosing among the alternatives offered requires taking into account various aspects such as technical, social and environmental, often in conflict with each other. The evaluation must not fail to take into account either economical efficiency or  financing constraints of the operation. Multi-faceted analysis techniques which facilitate the consideration of various points of view and manage conflict between various parties involved will prove to be advantageous.


Besides guaranteeing the maximum interfaceability with other data banks the results will be presented using easy to read and interpret report cards and graphs.
