Abstract Safety applications in VANET are fundamentally dependent on communicating safety messages. Such messages are delay-critical and transmission parameters need to be kept in check for effective communication among vehicles. As long term evaluation (LTE) is infrastructure based direct communication is not possible among vehicles, such messages need to pass through the infrastructure. In case of safety applications extra care needs to be taken as high speed vehicles are more reactive to delay than slow speed vehicles. This is because high speed vehicles change their positions more frequently. Higher priority needs to be given to such vehicles in order to lower the delay. Characterization of delay requirements is needed which in turn can be used to compute path loss, fading, transmission range, rate and access probability in order to satisfy the delay requirements. In this paper a scheduler is proposed for LTE network suitable for safety applications in VANET. This scheduler takes into account the vehicular speed (VS) and Vehicular Location (VL) to assign priority and resources. High speed vehicles receive a higher priority for allocation of network resources. Simulation of the proposed scheduler (PS) shows that it performs better in comparison to largest weighted delay first (LWDF) algorithm which is considered to be the best choice for development of safety applications in VANET.
