1. A signaling system for communicating traffic information comprising:
- (a) a plurality of radio beacons selected from a group consisting of fixed (TX-F) and portable (TX-M) radio beacons;
(b) a plurality of vehicle-installed mobile transceiver (TX/RX-M) for receipt of traffic information concerning hazardous areas or conditions;
(c) a plurality of user-carried transceiver (TX/RX-P) for receipt of traffic information concerning hazardous areas or conditions;
(d) an operations center for control of said vehicle-installed mobile transceivers and said user-carried transceivers comprising a services network comprising fixed and portable elements;
wherein said signaling system comprises AVI (automatic vehicle identification) technology for identifying and recording time of data received or transmitted by the transceivers;
wherein said AVI technology comprises transmitter elements having (a) operating frequencies authorized for AVI applications selected from a group consisting of 900-928 MHz;
2.45 GHz and 5.8 GHz;
(b) a voltage supply selected from a group consisting of batteries having a life of 10 years and solar cells;
(c) a range selected from a group consisting of up to 10 meters for installation at fixed locations and up to 100 meters for portable installation;
(d) electronic features selected from a group consisting of adapted AVI technology, surface technology (SAW), EPROM, EEPROM, ROM, and RAM memories having a storage capacity of at least 1024 bits;
(e) a permissible temperature range comprising a standard operating temperature of from −
40 degree C. to 85 degree C. and storage temperature from −
55 degree C. to −
125 degree C.; and
(f) a resistance to weather conditions.
