Intelligent transport systems (ITS) have recently attracted much attention, partly arising from the demands of improving road traffic safety and efficiency. 3GPP is addressing the communication needs associated to ITS and vehicle to vehicle (V2V) services as part of LTE Rel-14 enhancements, including unicast, multicast, and sidelink transport options. This paper summarizes the present status of 3GPP standardization, evaluates the different LTE based transport options, and compares the performance of LTE to an alternative V2V transport based on the IEEE 802.11p standard. Our investigations show that LTE multicast is more efficient than LTE unicast, which is constrained by limited downlink resources. We also observe a performance trade-off between LTE multicast and sidelink, where for high system load sidelink provides better reliability than LTE multicast for shorter communication ranges, while multicast outperforms sidelink for longer ranges. Finally, our results show that both LTE multicast and LTE sidelink outperform IEEE 802.11p in range and reliability for the considered scenarios.
