Abstract Intelligent Transportation Systems (ITS) aims to provide innovative services relating to dierent modes of transport and trac managementbr /> and enable various users to be better informed and make safer, more coordinated,br /> and #39;smarter#39; use of transport networks. Considering ITS applicationsbr /> that require information to be relayed multiple hops between cars, vehicularbr /> networks are poised to become the most widely distributed and largest scalebr /> ad hoc networks. Such challenges and opportunities serve as the backgroundbr /> of the widespread interest in vehicular networking by governmental, industrial,br /> and academic bodies. This paper tackles the great variety of Intelligentbr /> Transport System applications, its dierent used cases and security issues.br /> The objective of this tutorial is to integrate and synthesize some areas andbr /> applications, technologies discuss with all prospects.br /> nbsp;/p>
