Traffic and Roads - DRIVE integrated systems


The project is concerned with defining a global approach to the role of a common infrastructure in an Integrated Road Transport Environment (IRTE). The objective is to ensure that the functional requirements specifications of the common infrastructure are clearly stated, particularly from the point of view of the highway authorities responsible for overall traffic management.
The project is designed to complement others which are more concerned with system design and development. It is particularly directed to the integration of the various demands which might be made of a single road infrastructure. The project aims to provide the authorities and other actors with the means for directly influencing the specification of the IRTE to ensure that their specific requirements are fully recognised.
The functional requirements of infrastructure based road transport informatics (RTI) systems have been examined using a general systems architecture with 5 layers. This structure has been used to analyse the functional requirements of a number of RTI systems grouped into 7 application areas. The formal description technique developed is particularly suited to the analysis of integration scenarios. Although concentration has been on physical functions, the analysis has remained technology neutral.

The functional analysis has been supported by the TARSIM simulation model, which simulates processing and communication within the RTI application. Processing is represented by the reception and production of information packets. Processing and transmission rates are specified by the user, who can then study queues and bottlenecks in the system. Traffic is represented as a random process, which results in the generation of messages with exponentially distributed gaps at detectors and beacons. TARSIM therefore complements the analysis based on the formal description technique. TARSIM therefore supports evaluation, system comparison, prediction, sensitivity analysis, design optimisation, bottleneck identification and the establishment of hardware requirements and costs.

A functional specification for automatic debiting, which meets the requirements of the motorway operators of France, Italy and Spain for automatic toll collection, as well as the Rijkswaterstaat for road pricing, has been produced. The advent of automatic debiting technology and automatic ticketing opens the possibility of a better sharing of costs among all beneficiaries. One can distinguish between the suppliers of transport services, the users, the beneficiaries and the payers where users, beneficiaries and payers need not necessarily be the same people. To achieve global safety, environmental and efficiency goals it is necessary to adopt an appropriate pricing policy, which essentially means that all beneficiaries should be taken into account.
The main work of the project will be in two sections: functional specification and standardization / legislative aspects. The analysis of the requirements of different actors will lead to agreed sets of functional requirements and specifications. The second group of tasks will address the requirements for international standards relating to the IRTE.
The partners active in the specific work packages will report to a functional requirements committee which will implement the global systems approach to specifying the overall requirements of the IRTE.
Main Deliverables:
IRTE functional requirements, recommendations for standardization.
