Microscopic traffic simulation Leuven Ringroad

From 2019 to 2020
The Agency for Roads and Traffic Flemish Brabant (AWV) and public transport company De Lijn asked TML to conduct a traffic analysis of the Leuven ring road (R23).  The study analysed a new concept of ‘high-quality public transport’, and in particular its effects on the traffic situation on the Leuven ring road and its incoming regional roads.
In a next phase, the AWV will use the results of this study to design specific road sections and junctions along and around the R23.

For this study, TML used the Vissim software package to build a microsimulation model for Leuven. Subsequently, we designed dynamic lighting controls for the current infrastructure according to the 'maximum conflict-free' principle. This scenario served as a benchmark for comparison with the future scenarios of the 'high-quality public transport' concept design. For these future scenarios as well, specific lighting control systems have been designed with flexible public transport control. Thanks to TML's optimisation proposals to improve traffic flow in the HPT design, total loss times in microsimulation were reduced by about 40% for both car traffic and public transport.
