Either vehicle traffic or financial markets data is regularly broadcast in a fixed size packet over a wireless network in a push manner to one or more wireless receiver devices located within a particular service coverage region. A data center stores information specific to the particular region including drive-times strings metadata, drive-times data, drive-times route metadata, traffic incident data and financial markets indicators data. The data center decides upon a particular type of information to be placed into a payload of a next packet to be broadcast and pre-formats this information accordingly without receiving any information from the receiver devices. Data structures are provided which contain data representing the drive-times strings metadata, drive-times data, drive-times route metadata, traffic incident data and financial markets indicators data. |
