Macromodellering en microsimulatie kleine ring-Botanique

Multimodal Traffic Model Study of Brussels’ inner ring road

The feasibility study analyses the possibilities of covering the part of the city ring road between the Rogiertunnel and the Kruidtuintunnel, creating one long tunnel of 1200m. By means of micro-simulation as well as macromodelling, several variants were investigated. The traffic flow of the new tram line via the Pachecolaan was also investigated, as well as the crossability for soft road users.

Within the framework of the feasibility study, both macro-modelling (VISUM) and micro-simulation (VISSIM) were used to weigh the impact of different scenarios.

By means of a macro model created in Visum, the impact of a closure of the St-Lazar tunnel was shown by means of SLA analysis.
Since initially only counts from 2006 and 2014 were available, a 2006 scenario was made first. Based on this scenario, the 2014 situation was created and the results were compared with the more recent counts. Ratrun-traffic is also estimated. A second opinion was also carried out using the Musti urban model. This model confirmed our results.

Subsequently, by means of microsimulation in Vissim, different scenarios were evaluated at intersection level in order to estimate the impact on car, public transport and soft road users. The study area runs from the intersection with Rue Gineste to the intersection with Rue Royale.
Variants with and without cutting of the existing tunnel, a level crossing at Pachécolaan and central or decentralised location of bus/tram lanes were investigated.
