pplied to accelerate infrastructure deployment or if deployments will be managed by the governments. In some regions, the government agen- cies are mainly promoting pilot projects in order to benefit the economy of cities and regions by improving traffic efficiency, reducing emissions, and minimizing the risk of crashes. With C-V2X, mobile operator involvement can make additional, commercially motivated services available. The beneficiaries of these can be both subscribers and road operators.
