In this paper we consider a novel multimedia application, in which drivers may query multimedia clips captured by smartphones mounted on other vehicles. These multimedia clips visualize and voice-indicate the real-time traffic conditions on road segments ahead. We designed a systematic and exhaustive set of query processing strategies which differ from each other in terms of push versus pull, whether infrastructure communication is utilized, and whether metadata dissemination is separated from
