The possibilities for a comparison of Telematic Applications (traffic system management TSM) with other infrastructural improvements by the traditional methods are limitated. The socio-environmental influence and the real reactions on telematic applications have been not correctly integrated. That is why the proposed reactions have often been wrong.
The main objective is to give an overview of the existing infrastructure planing- and evaluation methods from a TSM-orientated point of view. Moreover there will be proposals for an improvement of these planing- and evaluation methods.
The benefit of this work is in a better predictability of the effects of Transport Management System (TMS) measures. In practise this leads to a better incorporation of such measures into integrated assessment procedures resp. procedures related to the specific TMS effects adaptation and accordingly a more objective results.
If it is a question of the assessment of TMS measures, microscopic models, plus survey methods, do particularly well. In general, these are also suitable for the comparison of TMS measures with other ones. As a result of this, the following suggested recommendations for further development in the direction of a ‘TMS planning instrument’ will be put forward:
- In the short term, improvements can be achieved using time-dependent apportionment models, microscopic demand modules, plus optimized survey methods. With particular regard to survey methods, a standardization of the enquiry methodology, plus greater facilities for transfer and amalgamation with other surveys, is to be aimed for.
- In the long term, greater integration of dynamic demand and network models will permit a raised level of accuracy of illustration. TMS-specific data collections ought to be fundamentally suitable for this. Behavioural reactions are an important prerequisite. With regard to a broad acceptance, the availability of open source simulation applications should be investigated.
