Practical test: Coordinated network-wide traffic management

The Traffic Management Amsterdam Practical Test (PPA in Dutch) began in the autumn of 2013: intelligent regulation of traffic in a specific area, network-wide and coordinated. This large-scale test encompasses a host of innovations including a highly advanced simulation model. Looking ahead in detail to the effects of modification is after all a crucial pillar of a regulatory concept.

Commissioned by the Directorate-General for Public Works and Water Management (Rijkswaterstaat, DVS), as part of the Traffic Management Amsterdam Practical Test (PPA), an integrated simulation model was developed for the Amsterdam-West region, including arrangements for the traffic regulation or access road division installations (VRI/TDI). More than 200 VRIs and TDIs are included in the model. For the test it was necessary to enable a number of modelling technologies to work together (a so-called hybrid system). This was a dynamic traffic model for the entire area (StreamLine) and a micro-simulation using VISSIM for the motorways and most important highways. The whole project was linked in real-time to regulatory algorithms developed by the TU Delft in Matlab. We calibrated the model system on the basis of Navteq data, Monica data, camera observations and ‘expert judgements’, among other things. Initially the model will be used to fine-tune the TU Delft’s regulatory algorithms, but the model will also play an important role in developing regulatory scenarios. The practical test began in the autumn of 2013.
