Improving road tunnel safety is extremely challenging due to the fact that even minor changes may have a major impact. Tunnel control centres have to ensure smooth and safe tunnel operations and they are in charge of tunnel monitoring. Tunnel operators often have to deal with complex scenarios as they have to manage several technical installations at the same time. PTV Transport Consult GmbH played a significant role in developing a real-time safety management system (ESIMAS) designed to support tunnel operators.
PTV’s method for data fusion and risk assessment is ESIMAS‘ core component which collects safety-relevant data from different detector systems to be used for online evaluation. This allows for early and reliable detection of critical incidents such as accidents or fire. Moreover, ESIMAS provides an expert system which identifies and recommends suitable measures that reduce the risk in tunnels based on the current security issues.
The information selected by ESIMAS will be prioritised and visualised so that the operators can take appropriate preventive measures (e.g. speed limits, tunnel closure, etc.). In the event of specific incidents, operators can take action as quickly as possible in order to reduce the risk or extent of damage in a targeted manner.
