RESilient transport InfraSTructure to extreme events

Periodic Reporting for period 1 - RESIST (RESilient transport InfraSTructure to extreme events)

Reporting period: 2018-09-01 to 2020-02-29

The overall goal of RESIST is to increase the resilience of seamless transport operation to natural and man-made extreme events, protect the users of the European transport infrastructure and provide optimal information to the operators and users of the transport infrastructure. The project will address extreme events on critical structures, implemented in the case of bridges and tunnels attacked by all types of extreme physical, natural and man-made incidents, and cyber-attacks. The RESIST technology will be deployed and validated at 2 pilots in real conditions and infrastructures. RESIST will use risk analyses and leverage and further develop recent exploitable research results in robotics, driving under panic, sensing and communications, to dramatically improve the speed and effectiveness, while reducing the cost, of structural vulnerability assessment, situation awareness, response operations and increased users’ protection under extreme events towards a high level of resilience of the transport infrastructure at 3 levels: a) increased physical resilience of bridges/tunnels by robotic inspection and predictive analytics; b) restoration of services/routes back to normal quickly and permission of a continuous flow of passengers and freight across different modes of transport soon after an extreme event, which will be achieved by rapid and accurate robotic damage assessment after extreme physical events, cyber security solutions, alternative secure and continuous communication under emergency operations (including integration of terrestrial and satellite systems) and increased cross-modal flexibility; c) clear and effective communication of transport operators and users, emergency responders and the public in the vicinity, to minimize the impact of the disruption on people and businesses, by exploiting real-time data, available networks, social media and mobile technologies to allow for real-time emergency information dissemination.
During the 1st period of the project M1 - M18 the consortium partners managed to engage a number of experts from the various fields relative to RESIST and extract a list of user requirements. This led, after a number of iterations, to the RESIST system architecture which subsequently led the technical work of the whole project.
In the technical part of the project the consortium partners produced excellent work bringing the project on a very good state for the second period. More specifically,
4 different custom-made new drones have been developed to cover both bridges and tunnels based on carbon fiber frame with lighter weight and increased agility. 2 sensor suites for contact inspection that already have given very promising results in crack width, length and modulus of elasticity measurements. New algorithms in image analysis for damage identification that have been developed in combination with 3D geometry coming from the photogrammetric module. Finally, the RESIST mobile app for rerouting of traffic due to an extreme event is already in its beta phase.
1. Actions will contribute to substantial improvement of smooth continuity of mobility of people and freight even in the case of serious disruptions due to natural or man-made circumstances:
During the period, in the context of WP 6 already developed the rerouting protocol for the traffic around the area of T9 bridge of EOAE. Considering that since multimodality is not fully developed and that we are still adding types of vehicles that differently affect traffic the gain from the module cannot be fully realized. Still we remain fully confident that by the end of the project the impact described in the DoA will be fully realized.

2. Major progress will be made regarding individual mode components' resilience to damage due to extreme weather conditions, including reduction of maintenance and retrofitting needs
Since the current cost of inspection (especially as a function in time and considering the hazards to human personnel) is by fact multiple times larger than the operational cost of RESIST this point of impact is certain to be achieved. Additionally, all modules of RESIST are being improved versus their previous iterations something that will allow for an even better system performance.

3. Contribution to achieve reliable modal interchanges allowing continuous fluid traffic flow even during or after disruption
Since multi-modality is still under development in the context of WP 6 this impact point cannot be presently realized. The fact of the matter is that the technologies and software packages selected in RESIST cover fully the requirements to complete realize this impact and we are fully confident that by the end of the project it will have been achieved. Additionally, RESIST mobility continuity module and the accompanied application has been presented to the RESIST end users as well as to external end-users and has received very positive feedback on its potential.

4. A high level of resilience of the transport infrastructure is an essential contribution to sustainable development and of impact on and adaptation to climate change conditions:
This point of impact is connected to the overall system behavior and it will be able to be achieved when the integrated system has been tested during the 1st pilot. As of now since all technical work is going to schedule and achieving set requirements we can be fully confident that it will be fully achieved
