Metro North
20053
From 2021 to 2028
Brussels Metro Line 3 will be extended by five kilometres towards Schaerbeek and Evere. TML is supporting Beliris by preparing a hyper-coordination file and programme and analysing the impact of the works on traffic.
The Metro North project involves the extension of Brussels Metro Line 3 in the direction of Schaarbeek and Evere. It will carry around 37,000,000 passengers a year. The new line will be five kilometres long and have seven stations: four in Schaarbeek (Liedts, Colignon, Verboekhoven, Riga) and three in Evere (Linde, Vrede, Bordet). Several of these will be intermodal stations by train (RER), bus, bicycle, and/or tram. The new metro tunnel, with a cross-section of 9.80 metres, will be dug with a tunnel boring machine, except for the passage under the tracks of the Brussels-North station. A new depot is being built at the STIB branch at Haren at the end of the line.
The hyper-coordination zone covers more than seven square kilometres and will later be defined and published in the Belgian Official Gazette. Within this zone, all construction sites are monitored by the hyperpilot and the Construction Sites Coordination Directorate to ensure the viability of public roads. TML is part of a team of experts supporting Beliris in its role of hyperpilot during the implementation of this project.
Prior to the works, traffic counts and data are collected from all modes. Tools are provided for the rapid analysis of the impact of planned worksites and the provision of selected traffic information. In addition, simulation tools for mobility analyses (at macro, meso, and micro level) and mobility plans are provided. A hyper-coordination file and programme are prepared, as well as a mobility plan imposing minimum traffic conditions. Finally, emergency scenarios are provided for calamities, the mobility impact of which is analysed.
During the works, the progress of the hyper-coordination programme is reported on the basis of mobility analyses on planned interventions and construction sites with mobility impact. These analyses can be done at micro scale (at intersections) and meso scale. The hyper-coordination programme and the mobility plan with minimum traffic conditions can be adjusted during the works. Historical data is analysed annually as part of ongoing monitoring to evaluate the impact of decisions on traffic in the hyper-coordination zone. During the works, attention is also paid to communication aimed at specific target groups in zones impacted by works phases. Furthermore, alternative mobility measures are drawn up in the event of an emergency and signalling plans are drawn up.
After the works, the hyper-coordination programme, mobility analyses, communication, and monitoring are evaluated. A mobility analysis is also carried out on the traffic situation in the context of the final reconstruction of the public space after the metro works. This will involve simulating different scenarios.
In the first half of 2021, prior to the works, the necessary traffic information will be collected, analysed, and supplemented by additional counts. The tools for rapid analysis and simulations will be provided and validated. In addition, the hyper-coordination file and programme will be prepared. Based on the available information on impact and timing of the planned construction sites (Metro North and others), the impact on the traffic situation and the construction site traffic of the major construction sites is analysed. Conflicts of yards with impact are detected and advised to adjust. Mitigating measures are drawn up for unavoidable traffic disruption.
During the construction site phase (2021 - 2029), the construction site is monitored in terms of traffic impact for all modes of transport. To this end, a monitoring system will be developed. Several variants will also be analysed and weighed up during this phase.
For the final reconstruction after the site phase, the traffic situation of several variants will be analysed and reported. This report will make a proposal of the preferred variant.
In the preliminary phase, TML will provide Telraam data for the analysis of different traffic modes. Telraam devices will also be added in the hyper-coordination zone during the course of the project. In addition, our expertise from previous road works impact management cases will be used in drawing up the hyper-coordination file and programme.
During the worksite phase, TML will assist Beliris with hyper-coordination in the zone. We timely identify planned construction sites in the zone and estimate and report the impact on traffic conditions and works to the subcommittee.
For planned interventions and construction sites with mobility impacts, TML will be in charge of micro-scale simulations. For this, we use the Vissim software.
