The objective of Quartet plus is to demonstrate a European platform for launching transport telematics in urban environments on an open market. This will be achieved by comparative evaluations and by operating an information infrastmcture, multi modal information and public transport management. Six European cities are included in Quartet plus; Athens, Birmingham, Gothenburg, Stuttgart, Toulouse and Turin. The partner responsible for the Gothenburg test site is the Swedish National Road Administration (SNRA).
In three of the sites - Gothenburg, Stuttgart and Turin - evaluations of long term scenarios have been performed. It was agreed that the scenarios should be distinct, or extreme, and that they should be compared to a reference case. The list of common indicators defined within the Quartet plus project were to be used in order to facilitate comparison of results.
For Gothenburg, the so-called TOSCA methodology was used. TOSCA, an acronym for Test- Site-Oriented Scenario Assessment, was a Swedish evaluation project performed in two phases between 1990 and 1996 with Transek as the co-ordinator. The scenario methodology is as much as possible based on results from field trials in Gothenburg and elsewhere. The analysis also includes a number of parameters that are difficult or impossible to measure, and these have been assessed by a panel of experts. The parameters mainly concern technical development, user valuations, implementation levels, change in travellerÕs behaviour due to the systems, level of quality of the information and the control systems, and compliance with recommendations. A regional network model is then used to extrapolate the effects to the whole region. The result can then be used as a basis for a cost-benefit analysis of the scenarios.
The integrated road and public transport environment (IRTE) in Gothenburg is managed by the City of Gothenburg Traffic & Public Transport Authority in co-operation with the SNRA.
In the perspective of the society, there are several reasons for advocating further deployment of transport telematics. By providing high quality information, the travellers are assisted in becoming flexible and can make more efficient choices. Likewise, by controlling the traffic streams with a higher degree of intelligence and adaptation to the situation, the existing road space can be used more efficiently. This leads to a lower pace of the infrastructure investments, money is saved and less land space needs to be used by the transportation system. From a traffic policy point of view, there are high expectations that transport telematics can be an important means to reduce the extent of harmful emissions and the number of traffic accidents and personal injuries.
This Quartet plus scenario evaluation provide a deeper insight into the effects of two distinct scenarios, one that increases the efficiency of car traffic and one that encourages public transport. By combining the results from the Gothenburg scenarios with results from other Quartet plus test sites, the traffic authorities in Gothenburg and other European cities can get ideas of how to deploy and operate transport telematics in a beneficial way.
