Cost-Effectiveness of Sharing Roadside Infrastructure for Internet of Vehicles

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. The authors estimate that government could save about one-fifth of the nationwide cost of safety RSUs in the U.S. if they are shared with Internet service providers. They also estimate an increase in social welfare from sharing safety RSUs. In the case of sharing smart streetlights, the authors find that nationwide benefits could be up to one-third higher than with sharing of safety RSUs. The prices that maximize government savings and social welfare may differ. However, they find that maximizing government savings results in near-optimal social welfare. The benefits of sharing would increase significantly if the Internet traffic or DSRC penetration grow over time, as expected.
