PROBLEM TO BE SOLVED: To collect and provide evidence and witness information for determining responsibility accurately in most traffic accidents where vehicles may be involved, persons may get injured, vehicles may be damaged, and insurance claims must be processed. SOLUTION: Information related to a vehicular environment is disseminated in a multi-hop node broadcast network consisting of a plurality of nodes 125. Vehicles and roadside units are equipped with the nodes. An event is detected at a location by a source node. In response, zones are associated with the location of the source node. Each zone is logically asymmetric and disjoint from the other zones. An alert message is broadcast, received, and then rebroadcast by the other vehicles according to the locations of the vehicles in the zones. The nodes can also disseminate witness information.
