Comparison of LTE and DSRC-Based Connectivity for Intelligent Transportation Systems

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...
