Decentralized Congestion Control (DCC) for 802.11p based inter-vehicular communication (V2X) is a critical mechanism for distributed wireless resource allocation of future connected intelligent vehicles. Studies so far mostly focused on optimizing resources for a single Cooperative Awareness service, whereas future connected intelligent vehicles will be based on multiple heterogeneous new V2X services. In this paper, we present a Facilities-layer DCC, currently being standardized in Europe, capable of handling heterogeneous V2X services and evaluate its integration impact with legacy DCC mechanisms. We first emphasize significant wireless resource under-utilizations
and application performance degradations stemming from conflicting decisions between legacy and Facilities-layer DCC. We then show the capability of the DCC mechanism purely based at service layer and illustrate its flexibility for agile wireless resource
allocations between V2X services for intelligent vehicles.
