The project's objective is to create an integrated model structure appropriate for RTI Policy analysis and then to use this model structure in order to produce evaluation criteria for RTI system effects.
FRIDA's main objective was to provide a modelling framework for an integrated dynamic analysis of travel and traffic. This framework essentially aims at describing and specifying the modelling of the subsystems of the driving task (individual and collective), and most importantly to establish their integration.
The research dealt with the following objectives:
the specification of an integrated modelling framework, as well as the definition of a set of performance criteria for evaluation resulting from models within the framework;
the investigation of a travel behaviour subsystem focused on the dynamics of pretrip time choices, which are most likely to be affected by the introduction of the road transport informatics (RTI) systems;
the investigation of an individual on the road (driver) behaviour subsystem, concentrating on crucial aspects, such as adherence to a controlled traffic environment;
the investigation of traffic analysis and management subsystems referring mainly to issues that improve the predictive ability of traffic management models, following their adaption to the integrated road transport environment (IRTE) requirements.
The project considers that the application of RTI demands for its analysis a modelling framework capable of integrating 3 sub-models - travel behaviour, driver behaviour and traffic modelling - into a coherent whole.
The project will define all the elements of that framework and will suggest a structure for organizing these elements into an all-embracing model system.
The proposed technical approach is based on defining model forms appropriate to capture the essential features of RTI-based policies by adequately adapting existing operational models, adapting theoretical models and, eventually, proposing new models if required.
Using input from other Projects in task areas T203 and T301, specifications will be defined for the above models.
The proposed modelling framework will also produce a set of evaluation criteria to be used as an input to projects in task areas 206 and 207.
In return, initial findings from projects in task areas 206 and 207 will give feed back to FRIDA and will be combined with a more in-depth investigation in the next phase of the project.
The results of the final phase of the project will be the finalisation of the modelling framework, as well as the formulation of a final set of classified evaluation criteria, along with suggestions on their use for evaluation of RTI effects.
