CHAPTER 1 
INTRODUCTION: INTELLIGENT VEHICULAR COMMUNICATIONS
1.3.1.2 International Standard Organization (ISO)
In 1993, ISO created the ISO/TC 204 that covers ITS activities. The ISO/TC 204 activities are per-
formed in 16 operating teams. The protocol suite that’s standardized by ISO is denoted as continuous 
air interface long- and medium-range (CALM). CALM considers infrared (IR) communications, ad-
ditionally as radio systems and includes communication technologies, such as GSM, UMTS, DSRC, 
and so forth. ISO/TC 204 WG 16 and ETSI TC ITS are closely cooperating with each other in effective 
transportation models. CEN in collaboration with ISO/TC 204 ITS organized ISO/TS 19321 in line 
with the Vienna agreement (a technical cooperation between ISO and CEN). As per C-ITS, informing 
the driver about the traffic situation and road regulation forms a vital component of road operations. See 
Table 1.3
 for the work group ISO/TC 204 and ITS applications.
By using messages such as cooperative awareness messages (CAM), decentralized environment 
notification messages (DENM), or basic safety messages (BSM) we can notify the road user about 
the traffic situation in the C-ITS, an initiative undertaken by ISO/TS 19321. Furthermore, ISO/TS 
19321:2015 stipulates the in-vehicle information (IVI) data organizations that are required for various 
ITS services (e.g., refer to ISO/TS 17425 and ISO/TS 17426) for exchanging information between ITS 
stations as depicted in 
Table 1.2
. ISO/TS 19321:2015 latest edition is referenced by ETSI/TS 102 894-2 
V1.1.12, ITS; users and application requirements.
1.3.1.3 ETSI
ETSI is a standard for ICT, which includes fixed, mobile, radio, converged, broadcast, and Internet 
technologies and is legitimately acknowledged by the European Union as a European Standards Or-
ganization. ITS can significantly contribute to a cleaner, safer, and more efficient transport system. In 
2010 the European Parliament and Council adopted the ITS Directive to accelerate the deployment of 
these innovative transport technologies across Europe. This directive is an important instrument for the 
coordinated implementation of ITS in Europe. It aims to establish interoperability and seamless ITS 
services while leaving Member States the freedom to decide which systems to invest in. Under this
