Transport simulations

The transport simulation models are run by informatic programs in order to solve problems that arise during the management and planning of transport situations that cannot be addressed by regular means. Among its main uses there are:

  • Network analysis
  • Passenger transport analysis
  • Elaboration of models of transport demand and transport planning
  • Logistics and route optimizations
  • Territory management

CINESI disposes of two different tools for the creation of the traffic models, depending on the scope of the study:


TransCAD is a model of macroscopic simulation used in studies of transit flow distributions in interurban roads and highways.

Throughout Geographic Information Systems (GIS) TransCAD allows storing and analysing data related to transport and mobility traffic in any mode.

Here some examples:


Private vehicles

Public transport



AIMSUN offers microscopic simulations of traffic flow in urban networks, what permits individualised analysis of each vehicle and section, as well as real time data outputs.

From the simulation of the different transport modes and the visualisation of all the mobility interactions, it is possible to evaluate the impact of future actions in the urban road network. This allows detecting premature critic points before the actions are implemented.

Here some examples:


Display of the Service Level in roads

Functionality analysis of junctions


These models offer the possibility of evaluating action proposals in the short, medium and long term, through the study and comparison of all the parameters of traffic performance (flow intensity, capacity, service level, delay time, congestion, queue generated, etc.). For this reasons they have become a key tool during decision making processes and the study of alternatives.
