Vehicular communications are becoming a reality due to the investments by stakeholders like car manufacturers and public transport authorities. The building blocks of the "Vehicle grid" (radios, Access Points, spectrum, standards, etc.) are coming into place enabling a broad gamut of applications that range from navigation safety, intelligent transport, entertainment and urban sensing. Vehicular protocols and applications, however, must be carefully tested before deployment in the urban grid and introduction to the users. This validation must be carried out progressively in simulation, emulation and small scale testbed environments.
