TRT uses the best software tools and models on the market related to the transport sector and is able to develop applications tailored on the specific needs of its clients.
In this respect, a key qualification of TRT is funded on its specialization in transport modelling for the demand analysis and forecasts, in order to assess the interaction between transport system and socio-economic and territorial system within the strategic planning of the policies and transport investments.
The models are applied at urban, metropolitan, regional, national and European level.
PTV VISUM is a software package widely used for the analysis and planning of transport demand. It is based on a GIS system and allows to develop solutions and strategies for the transport system at different scales. TRT uses PTV VISUM to create transport models to support Sustainable Urban Mobility Plans and regional traffic forecasts. The European scale models TRUST and TRIMODE are developed in PTV VISUM.
This software belongs to the category of microsimulation models, i.e. models that can reproduce the vehicular mobility at microscopic scale up to each vehicle detail, allowing also to show in and extremely detailed way the geometric characteristics of the road network, roadway width, number of lanes, traffic signal timing, diameter of roundabouts, etc. The simulation of traffic demand, dynamically performed for a certain period of time, allows to highlight phenomena as the tailback making up and to calculate waiting times at crossroads, turning points etc. This software is therefore of particular interest for the evaluation of detailed design solutions for planning. AIMSUN also allows the creation of models at scale ‘meso’, that means with a level of detail in between microsimulation and the traditional strategy models
VISSIM is part of the PTV Vision Traffic Suite, i.e. the integrated platform of transport planning tools including VISUM. As AIMSUN, this software belongs to the category of microsimulation models, i.e. models that can simulate mobility at the microscopic scale to the level of detail of individual vehicles.
Whether comparing junction geometries, analysing public transport priority schemes or considering the effects of certain signaling, VISSIM allows you to simulate traffic patterns exactly. Motorised private transport, goods transport, rail and road related public transport, pedestrians and cyclists, VISSIM displays all road users and their interactions in one model.
The software allows to realize System Dynamics models, which are models able to simulate the temporal evolution of systems comprising several elements related to each other and especially when those connections attain feedback phenomena. This type of models can be easily adapted to a variety of applications in different fields. In particular, TRT contributed to realize ASTRA model with VENSIM, in order to analyze in an integrated way the relation among the transport system, the economic system and the environmental effects. The model was created and is updated as part of research projects at European level, for which it is used to analyze issues such as the impact of infrastructural or technological investments in transport sector or the impact of energy costs.
Advanced micro-analytical traffic evaluation tool used for intersection (junction) capacity, level of service and performance analysis. It can be used to evaluate and compare capacity, level of service and performance of several alternative treatments involving signalised intersections, roundabouts, single-point urban interchanges, signalised midblock crossings for pedestrians. This software allows to simulate and compare alternative intersections layouts and to assess the impact of a new designed intersection.
Tool for describing and analysing swept paths for all types of steering vehicles, from the cars to the aircrafts. It permits continuous control of their manoeuvres guaranteeing high design quality (including junction and roundabout analysis) and the most efficient layout of organized spaces like shopping centres, logistic platforms, freight yards, intermodal centres, petrol forecourts and service areas, airports, parking areas, etc.
It includes ArcReader, ArcView, ArcEditor and ArcInfo, a package of software products that can be customized according to the needs of the client. These products share common applications, user’s interface and environment of development. ArcGIS provides an integrated operating system for management, editing, analysis and visualization of spatial data.
Autocad Civil 3D
Specialized software for design of works in civil engineering, notably regarding road and rail transport infrastructures and for the analysis of land use development and water resources. The suite of Autocad softwares allows for a complete control of a project’s phases: elaboration, management, coordination, overview of options, analysis of performances and preparation of the documents needed.
TRT has carried out several risk analysis through the @RISK model, particularly referring to the financial plans. The risk analysis within the transport projects is important and allows to quantify the contingencies. Through the risk analysis the confidence intervals of the demand estimation will be identified as well as the financial variables which could affect the estimations.
The transport and land use integrated model MEPLAN is a package of models for the analysis and evaluation of territorial and transport policies. Due to its flexible structure, MEPLAN can suit to very different applications in terms of demand segments, economic sectors, transport modes, number of areas, etc., simulating explicitly intermodality and with the sophisticated level of details as desired. MEPLAN is used by TRT both as a multimodal transport model and for the analysis of road traffic demand.
