Vehicular networks have the potential to improve road safety using Dedicated Short Range Communications (DSRC) technology, but substantial investment in roadside units (RSUs) is required. DSRC can be simultaneously used for safety and non-safety applications. If local governments share RSUs deployed for safety or smart streetlights with other kinds of service providers, then the respective costs can also be shared, thereby reducing costs for the government. We estimate that government could save about one fifth the nationwide cost of safety RSUs in the U.S. if they are shared with Internet service providers. We also estimate an increase in social welfare from sharing. The prices that maximize government savings and social welfare may differ. However, we find that maximizing government savings results in near-optimal social welfare.
