Abstract
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.
