An extended tester for cooperative intelligent transport systems

Abstract

C-ITS (Cooperative Intelligent Transport System) equipments are usually validated using testing procedures. The ETSI organism provides a set of test suites to check the conformance of communication protocoles implemented on these equipments. An adapted interface (denoted Upper Tester) has to be developed on any equipment which requires to be tested. In order to provide validated C-ITS equipments, the need to check the correctness of all functional parts becomes of high interest. One of the main functional part of a C-ITS equipment is to trigger automatically specific events when some conditions are satisfied. In order to test these event triggering conditions, we may emulate the environment (with its sensors) with an appropriate interface (denoted extended upper-tester). Moreover, a C-ITS equipment is expected to achieve manual events, such as opening a salt container in case of recovering slippery roads. Its execution could trigger conditions to send some appropriate messages as slippery roads ahead. For this purpose, we designed an extended Upper Tester from the one introduced by ETSI. Its aim is to manage the manual and the automatic triggering conditions and to test the results of these events. In this paper, we present this extended set of tests and their implementation in a real deployment project (SCOOP@F) of a complete C-ITS architecture.
