SCBA R0-North

From 2019 to 2021
The Flemish government has plans to redesign the Ring around Brussels (R0). In preparation of this, among other things, a SCBA is being made in two phases (loops). Currently, loop 1 has been completed and loop 2 has been started.
The Brussels Ring Road (R0) is old and outdated infrastructure. The various sections of the Ring Road were built gradually. The first road section, between Strombeek-Bever and Groot-Bijgaarden, was already opened in 1958, on the occasion of EXPO 58. Given the period in which it was built, the Ring Road is very car-oriented, with movements across or under the Ring Road leaving little room for other road users and the Ring Road forming a barrier. In terms of traffic safety, the infrastructure has not been built in accordance with the current rules. Moreover, the Ring Road does not currently function well for the current traffic volumes. The road is an important artery to and from Brussels, but also for traffic going around Brussels. Today, there is daily congestion on the Ring Road - even outside the rush hour and at weekends. In addition, accidents regularly occur, which adds to the congestion. This in turn leads to cut-through traffic and reduced quality of life in the surrounding municipalities.
The redevelopment of the R0-North, from the R0 x E40 interchange in Groot-Bijgaarden up to and including the R0 x E40 interchange in Sint-Stevens-Woluwe, will be considered in its entirety with a view to drawing up a new Regional Spatial Implementation Plan (GRUP) to anchor the necessary land-use changes for this redevelopment.
The Regional Spatial Implementation Plan (GRUP) 'Spatial redevelopment of the Brussels Ring Road (R0) - North section' is being implemented in several phases. In the first phase (loop 1), a lot of study work has already been done, such as a social cost-benefit analysis (SCBA), an environmental impact report (plan-MER), the Spatial Safety Report (RVR), the Traffic Safety Impact Assessment (VVEB) and the future proof screening. All of this is guided and supported by the design research carried out within De Werkvennootschap. The result of all this study work can be found in the scoping note of loop 2, which is available for download on the website of the Department of Environment and Spatial Development.

Our work consists of preparing the social cost-benefit analysis (SCBA). The SCBA of loop 1 has been completed, and the SCBA of loop 2 is being drawn up.
The SCBA systematically compares the social costs and benefits associated with the plan. The word ‘social’ indicates that the costs and benefits are analysed from society's point of view. Hence, not only the financial effects are analysed, but also elements with a value for society such as environment, safety, reliability, landscape etc. are taken into account. These calculations are made in detail and then discounted to a single balance that expresses the social return of the plan alternatives.
The overall conclusion of loop 1 is that the G1A2 plan alternative scores best; slightly better than the G2A1 alternative. The G3A1 alternative scores worst; with a barely positive benefit balance. This is mainly due to the difference in accessibility or mobility benefits. G2A1 scores slightly better than G1A2 on road safety.
The external costs on emissions score moderately across the board, with negative benefits for emissions and clearly positive benefits for the environment. The external costs for nature show a mixed picture.
