This system should provide more complete traffic monitoring than existing systems, and do so at almost no cost to the service provider. The project will be evaluated in a simulation. The system uses a combination of clustering and epidemic communication to find and disseminate traffic information. To work in realistic setting the system must be able to accommodate dynamic traffic patterns. To efficiently use the communication medium the system must impose a hierarchy on the peer-to-peer network. To accurately test the system we will use sophisticated automobile traffic simulators along with realistic communication simulators. This project could become a very useful system, saving millions of human hours and dollars. ]]>
