There is the class TraCICommandInterface which provides access methods for such data like getRoadId().

In the class TraCIDemo11p you can find an example how to get this information. It basically boilds down to performing the following steps:

TraCIMobility* mobility = TraCIMobilityAccess().get(getParentModule());
TraCICommandInterface* traci = mobility->getCommandInterface();
TraCICommandInterface::Vehicle* traciVehicle = mobility->getVehicleCommandInterface();
traciVehicle->getRoadId();
