摘要：Intelligent transportation system (ITS) is an application which provides intelligence to the transportationand traffic management systems. Although the word ITS applies to all systems in the transportation but asper the European union directive it is the application of Information and communication technology in thefield of transportation is defined as ITS. The communication technology has evolved greatly today from2G/3G to long term evolution (LTE). In this paper we focus on the LTE and its application in the ITS. SinceLTE offers excellent QoS, wide area coverage and high availability it is a preferred choice for vehicle toinfrastructure (V2I) service. At the same time the LTE customer base is increasing day by day which resultsin congestion and accessing the network to send or request resources becomes difficult. In this paper wehave proposed a group based node selection algorithm to reduce the preamble ID collision otherwise thisuncoordinated preamble ID transmission by vehicle node (VN) will eventually clog the network and therewill be a massive congestion and re-transmissions attempts by VNs to obtain the random access channel(RACH).
