    Abstract

    Automated driving has attracted enthusiasm worldwide with its potential to transform mobility and realize transport, economical and societal benefits. Gaining perspectives from previous V2X trials in 5G-Drive project, this paper is motivated to focus on two challenges encountered with LTE-V2X enabled automated driving: the impact of infrastructure antenna height in C-V2X supported automated driving and the influence of C-V2X in vehicle positioning, especially when satellite signals is unavailable. Two trials have been designed and performed in Finland, as an attempt to continue and examine the two LTE-V2X enabled automated driving use cases in previous V2X trials. The outcome shows C-V2X latency is affected when antenna height is low. Optimizing and configuring the antenna height is crucial in C-V2X enabled automated driving tests. Important lessons on RTK, Inertial and C-V2X enabled automated vehicle positioning are drawn from the trials, where the enhancement of C-V2X could be augmented by testing and strengthening the GNSS signals.
