According to the Spanish Directorate-General for Traffic (DGT), a significant number of accidents occur in Spain while a vehicle is being repaired or waiting for roadside assistance. In order to try to reduce the numbers, the DGT has proposed some connected solutions such as the V-16 light signal and the V-27 virtual triangle. This paper proposes an approach to the software and hardware implementation of these devices. For the hardware design, a modular system based on MCU and the real-time operating system FreeRTOS has been chosen. This would allow power saving and future modifications or upgrades in simpler and remote way. On the other hand, the designed software platform allows to collect and process both the incidents generated by this device and those published by the DGT in order to send them to the V-27 application on an Android system. It has been possible to develop a modular hardware device with a relatively low cost and a potentially scalable functional software platform.application/pdf11engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Road SafetyMCUIoTReal-Time Operating SystemFreeRTOSAndroidSignalinginfo:eu-repo/semantics/bookPartinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1007/978-3-031-64106-0_44
