Periodic Reporting for period 1 - SAFE STRIP (Safe and green Sensor Technologies for self-explaining and forgiving Road Interactive aPplications)

Teaser

Summary

SAFE STRIP aims to introduce a disruptive technology that will achieve to embed C-ITS applications in existing road infrastructure, including novel I2V and V2I, as well as VMS/VSL functions into low-cost, integrated strips markers on the road; to make roads self-explanatory and forgiving for all road users (trucks, cars and vulnerable road users, such as PTWs riders) and all vehicle generations (non-equipped, C-ITS equipped, autonomous), with reduced maintenance cost, full recyclability and added value services, as well as supporting real-time predictive road maintenance functions. The vast potential of SAFE STRIP will be demonstrated through applications for: 1) Cooperative safety functions for enhanced ADAS/ARAS equipped and non-equipped vehicles, 2) Road wear level and predictive road maintenance, 3) Road work zones and railway crossings warnings, 4) Merging/intersection support, 5) Personalised VMSâ€™/VDSâ€™ and Traffic Centre Information, 6) Dynamic trajectory estimation and interface to automated vehicles, whereas it will open a new channel to a vast array of 7) Supportive added value services (such as Virtual Toll Collection and Parking booking and charging). It will be evaluated in a test bed in Spain and in France and 2 closed test tracks in Italy and in real life conditions in Greek and Italian highways, with 4 car and 3 PTW demonstrators. This very challenging task is undertaken by a muldisciplinary and complementary Consortium of 18 Partners from 6 countries, with a good representation of all stakeholders.

Work performed

Project administrative and technical & innovation management (WP8) ensured the smooth progress of the project in all aspects. 17 Deliverables have been submitted in the period, undergoing internal peer review processes. A tool has been developed (IPR registry) to support continuous reporting of IPR of Consortium Partners. WP1 has been completed resulting in the project stakeholders needs recognition, accidents/incidents statistics, standards and regulations review, the project Use Cases definition, prioritization and detailed description and the benchmarking of the relevant market (materialized through an on-line database). Collaboration with SAFER-LC project has emerged for the materialization of the railway Use Case. A Use Case Guide has been published in the web site. In WP2, system architecture, sensor specifications, and requirements for all fabrication, installation, maintenance and encapsulation aspects have been finalized. The vehicle detection system, the vehicle identification system and the nano gas sensor have been designed. The first solution that encapsulates energy harvesting, energy storage, sensors in one integrated strip is available and has been evaluated. C-ITS protocols to be used have been defined. The first risk assessment of the project has been conducted. The first DMP is in place. In WP3, the different On Road Unit parts are in place and preliminary tested. The first integration in Tire Pressure Monitor system has been done and the relevant algorithms are in place. All communication modules breakout boards and the custom development board of Colibri i.Mx7 Solo have been completed. The hardware modules and on-board units that will be able to host the C-ITS communication standards and services have been determined. The required C-ITS layers have been also determined per vehicle demonstrator for each use case. Development and testing of C-ITS protocols for equipped demonstrators have partially finished. The OVU for the demonstrator vehicles has been designed and development of C-ITS stack for the specific OVUs has started. Communication module for autonomous demonstrator has been defined and interface to SAFE STRIP has been specified. The energy management board for the ORU and the RSB is ready and the first miniaturized integrated road platform is available. In WP4, the signal map has been completed and a set of scripts have been implemented that automatically derive the data structure written in the target language and to be embedded in the communication modules. Two different algorithms for friction estimation have been developed and experimentally tested. All intended applications have been defined/ designed and development has started. In WP5, HMI elements and strategies have been designed to be tested in the upcoming period in driving and riding simulators. The test protocol for first simulator tests is in place. DSS algorithms and the personalization layer of the HMI strategy are in place. The tape material for strips installation is defined. Preliminary testing has been performed for equipped and non-equipped vehicles. A detailed iterative and incremental technical validation plan has been prepared and submitted in this period. The 1st technical testing round has been completed. In WP6, the initial report in user trials evaluation framework and plans has been submitted. The overall evaluation framework and the full experimental plans for the 1st round of user trials have been described. The test infrastructure of the project has been defined with detailed topologies. Logging mechanisms are also defined. The first impact assessment framework has been presented. In WP7, dissemination and communication strategy has been defined and dissemination material has been created, updated and issued. The website, social media and User Forum have been created and continuously updated. 26 news articles and one newsletter were published on the website, 17 presentations and 7 publications were released by the

Final results

SAFE STRIP aims at boosting cooperative system applications in the road environment by a revolutionary idea: offer their functionality through low-cost micro/nano sensor communities embedded in road elements (in road pavement tapes), thus not requiring costly sensors or infrastructural elements. The vast potential of SAFE STRIP will be demonstrated for equipped and non-equipped vehicles through safety and comfort C-ITS applications for drivers/riders and infrastructure operators. SAFE STRIP introduces innovation on all layers as follows: Sensors-Intelligent infrastructure strips with networking capabilities, operating with minimum maintenance in the harsh all weather conditions of a real road environment &with partial energy autonomy; Applications - C-ITS for ALL functionalities at low cost and with high reliability & extendability; Operations - More pragmatic approach to the design of emerging and future communication technologies, mainly those destined for the road/vehicle interaction that may be deemed ubiquitous. SAFE STRIP impacts are expected on scientific field, road safety, cost-effectiveness and societal changes. Overall, the key targets are namely: reduction of highway fatal accidents â‰ˆ 5% - 8%; reduction of fatal accidents at specific traffic scenarios (i.e. merging/intersections) â‰ˆ 15% - 30%; cost saving for infrastructure â‰ˆ 50%-95% and cost saving for driver/rider â‰ˆ 95% - 100%.
