What does resilience mean for public transport systems?

Operational resilience

In order to provide at least limited services in case of a threat or an incident, crisis plans are to be developed in advance with alternative mobility modes. For this purpose software will be produced, which can determine functional principles of the network from a large quantity of operational data using artificial intelligence and automatically find high-capacity diversions through simulation calculations.

Structural resilience

Underground stations and tunnels are to be laid out so that no essential load-bearing structures will fail in case of an incident. To this end, for example, new materials with particularly robust behaviour against fire and explosion can be used. It is also appropriate to keep ready replacement parts and repair systems for the rapid restoration of structures.

User-related resilience

In case of an incident, passengers must be able to leave the underground quickly and safely. For this purpose adapted concepts are to be prepared, taking into account the particular conditions in the tunnels between the stations, including the poor lighting and narrow escape routes compared to stations. In addition, new communications concepts will ensure that the passengers are informed promptly about changed mobility services.

Resilience cycle

The idea of the resilience cycle follows the principle of continuous improvement. The 1st stage is to prevent the occurrence of an incident. In the 2nd stage, measures are to be kept ready to effectively respond to an incident. In the 3rd stage, the public transport system is to be recovered as simply as possible. In the 4th stage, preparedness can be improved on the basis of the previous stages. Then the cycle begins again from the start.
