Threats and possible approaches of vulnerability assessment of natural hazards on road infrastructure

Berg H. P., Petrek N.

Journal of Polish Safety and Reliability Association

2018

Vol. 9, No. 3

1--10

Natural hazards are frequently causing disturbances for different types of infrastructures, in particular for transport systems. Flooding and storm are considered as major threats to these systems. Based on examples of natural hazards’ impact on roads, possible approaches of vulnerability assessment are described. In order to reduce the threats resulting from natural hazards on road transport, appropriate technical countermeasures to increase resilience and robustness for continuous road safety and mobility are necessary. Moreover, the behaviour of the driver is also an important factor to avoid accidents in case of specific weather conditions. Autonomous driving may support a reduction of accidents in the future and, in particular, necessary evacuation processes in cases of wildfires or hurricanes.

Process of Judging Significant Modifications for Different Transportation Systems compared to the Approach for Nuclear Installations

Petrek N., Berg H. P.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2015

Vol. 9, no. 4

511--520

The implementation of the CSM regulation by the European Commission in 2009 which harmonizes the risk assessment process and introduces a rather new concept of judging changes within the European railway industry. This circumstance has risen the question how other technology sectors handle the aspect of modifications and alterations. The paper discusses the approaches for judging the significance of modifications within the three transport sectors of European railways, aviation and maritime transportation and the procedure which is used in the area of nuclear safety. We will outline the similarities and differences between these four methods and discuss the underlying reasons. Finally, we will take into account the role of the European legislator and the fundamental idea of a harmonization of the different approaches.
