Vehicle Communications using IEEE 802.11p WAVE functionality includes structure and method whereby a smart phone (SP) linked to an On Board Unit (OBU) having WAVE functionality, and incorporating Automotive Telemetry Protocol (ATP), has at least one processor to configure the SP as a GUI for the OBU, and to enable WAVE authentication of the SP through a networked Road Side Unit. Preferably, the OBU opens, after a command from an ATP Client, a virtual connection for streaming data between the vehicle data bus and a remote server providing an automotive scan tool. Also preferably, the SP may use either cellular or IEEE 802.11 control signals to trialaterate its geographic position with greater accuracy than GPS, and to hand off the geo-position fixes to the OBU. Accumulated geo-location information may be reported to a remote server, providing a centralized geographic trend analysis of plural SPs operating with OBUs.

Methods for road safety enhancement use mobile communication device (MCD) onboard vehicle to share traveling data through inter-vehicle communication broadcasting, perform road hazard warning, enhance road navigation, and provide autonomous road assistance. The methods have a variety of vehicle status data, such as moving data, steering data, or indicator data, obtained through GPS or image capturing and recognition of instrument cluster of vehicle. The image capturing and recognition allows to get speed data from indication of speedometer, indication of left or right turn signal, steering action data corresponding to steering wheel rotation, and light-on indication of system status indicators. To facilitate that, the MCD may be placed in front of steering wheel, and, if applicable, also in coupling with movement of steering wheel. The MCD may perform relative positioning map-matching lane correlation and GPS-update-interval speed positioning to improve data quality regarding vehicle moving status.

Systems and techniques describe a collaborative road user safety service that interacts with a coordinating set of collaborative safety devices belonging to road users in order to interchange reliable information about road safety. A distributed ledger/blockchain is utilized in connection with the service to coordinate data exchange between collaborative safety device users and provide data subscribers with reliable safety data that can be used to automate ancillary technical processes. Collaborative safety devices can alert members to road safety issues and be used to confirm information about road safety by collecting sensor and telemetry data. Data subscribers can receive aggregated, anonymized, de-anonymized, or specific road user data pertaining to road users and define the terms of incentives to road users that “self-revise” if a road user's vehicle is a target vehicle via smart contract interfaces. Cryptographic token can be transferred to incentivize data sharing, accuracy, and safe road behaviors.
