%X 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. In this paper we discuss the important role of the vehicular testbed in validating models and protocols before deployment in large scale scenarios. We illustrate the concept using two case studies that were carried out in the UCLA open vehicular testbed.
