Project:
TRANSIT – Software for risk analysis in tunnel ASTRA 19004

Period:
since 2009

Partner:
HOJ Consulting GmbH

Matrisk performs tunnel risk assessment in accordance with the guideline ASTRA 19004 and ASTRA 89005. A self-developed proprietary software tool allows Matrisk a swift and cost efficient assessment of tunnel risks for a multitude of hazard scenarios in road tunnels, including traffic incidents, fires, dangerous goods incidents. Based on it, a plethora of safety measures can be evaluated and the optimal safety strategy identified by using the ALARP principle.
Matrisk is looking back on many successful application of the software tool, including the modelling examples documented in ASTRA 89007 and several highway tunnels throughout Switzerland and worldwide. While developed for Switzerland, the software tool can be used to assess tunnel risks anywhere in the world. As a developer of the methodology underlying the guideline, Matrisk is in a unique position to adapt the methodology to local circumstances and local problem settings.

Project:
Development of a policy for risks in tunnels of national roads

Period:
2011 – 2014

Partner:
HBI Härter AG (lead), HOJ Consulting GmbH

A policy was developed for the assessment of tunnel risks in the Swiss national road network and for the evaluation of measures to increase tunnel safety. Based on the ALARP principle acceptance criteria are established. In the accompanying documentation, a comprehensive risk model is discussed, which takes into account dangerous goods accidents and major fires and the consequences of maps based on CFD simulations.

Project:
Development of a best practice method for
Risk modeling for road tunnels

Period:
2009 – 2011

Partner:
HOJ Consulting GmbH

In this research project an innovative method for determining risks in road tunnels has been developed. Based on observable indicators such as DTV, the proportion of heavy traffic, the lines, etc., the risks to road users are calculated using Bayesian networks. The concept allows to consider complex relationships and to calculate local site-specific risks. In this project, a new generation of risk assessment in the road system was launched, which can be applied also to other types of roads.

Project:
Risk analysis Tromsø Tunnel

Period:
2009

Partner:
HOJ Consulting GmbH

For the first time a newly developed risk analysis for tunnel systems based on Bayesian networks and homogeneous segments was applied for a tunnel system with 7 tunnels, roundabouts and car parks. The risk for road users could be determined quantitatively and consequently sufficient safety could be ensured for the road users by the project managers.
