Stakes

  • CEA-Leti’s contribution to the SAFESTRIP project has been specifying general project sensors and developing on-road sensors.

  • Sensor specifications have been drawn up to fulfil the need expressed in the use case scenarios defined by project end users. These specifications are for road sensors but also for
    all other sensors that cannot be installed on the road and need to be connected to the main infrastructure network platform.

  • The main contribution of CEA-Leti has been the specifications, development, testing and integration of the «On-Road Unit» (ORU), the central part of the «On-Road Platform», which allows acquisition of on-road sensor measurements.

  • The ORU has been designed to collect data from the project partners’ sensors. It is connected to a nano-based gas sensor developed by CNR and a dynamic vehicle detection unit developed by CERTH.

  • The ORU has been designed to collect and transmit data from other sensors as well as humidity and temperature data based on a Bluetooth Low Energy transmission protocol implemented in a very low power, low profile system.

  • The combined on-road data allow this global SAFESTRIP system to improve road safety through car localization and speed and friction measurements for the global external conditions.

  • SAFESTRIP merges data from on-road sensors with data from all other system and displays it to end users via a dedicated vehicle on-board unit.

OBJECTIVES

  • Project Aim 1. Development of a novel micro/nano sensor system called SAFESTRIP, which is integrated into road pavement tapes/markers, to provide advanced safety functions to all road users at a fraction of the cost of existing I2V/V2I nodes and roadside equipment (VMS, VDS, etc.).
    Project Aim 2. Support for predictive infrastructure maintenance through dynamic road embedded sensor input. Project Aim 3. Provision of road infrastructure (mainly highways and interurban roads but also ring-roads and some rural roads) that is self-explanatory (personalized own language information and preferred system format for each driver/rider) and forgiving (key I2V/V2I information provided to vehicle cooperative system, e.g. dynamic speed limit, friction coefficient factor) for all vehicle types.
    Project Aim 4. Extension of this concept to parking areas and key intermodal nodes, e.g. railway level crossings, port loading/ uploading areas, logistics facilities and, above all, work areas.
    Project Aim 5. Order-of-magnitude reduction of infrastructure operating (VMS/VSL information and toll collection functions), installation and maintenance costs, making infrastructure almost energy autonomous and its modules fully recyclable.
    Project Aim 6. Provision of key information on road, weather and upcoming traffic conditions to C-ITS-equipped and autonomous vehicles to support dynamic trajectory calculation and optimization.
    Project Aim 7. Support for a wide range of added value services (information “pushed” to driver/rider) and facilitating of SAFESTRIP rapid market deployment and sustainability through efficient business models.
    Project Aim 8. System appraisal in a controlled environment (test beds in Spain and France and two closed test tracks in Italy) and in real life conditions at two locations (highways in Greece and Italy) using four cars and 3 PTW demonstrators. Performance validation, user interface evaluation and acceptance aspects, and finally, assessment of system impacts on safety, mobility, the environment and European industrial competitiveness.


IMPACT

  • Project scientific impacts include:
    • Micro and nano sensors in road applications
    • Easy and cost effective dynamic information-based infrastructure monitoring
    • Much more accurate hybrid estimation of road friction
    • New V2X communication possibilities through deployment of latest 802.11p wireless network infrastructure hardware.
    Project safety impacts include:
    • Support for driver in most critical and dangerous conditions in a highway environment
    • Enhanced on-board security functions through friction coefficient calculation.
