DEVICE AND SYSTEM FOR COLLECTING TRAFFIC INFORMATION AND RECORDING MEDIUM STORING CONTROL PROGRAM THEREFOR

PROBLEM TO BE SOLVED: To obtain a traffic information collecting device which can collect traffic information and processing the collected information fast in real time. SOLUTION: Cell assembly and disassembly(CLAD) circuits 21-1 to 21-n of subordinate parts 2-1 to 2-n have a function for conversion between data and cells and impart traffic information into ATM cells when data are assembled into cells. A traffic information measuring circuit 11 of a control part 1 counts cells arriving in both transmitting and receiving directions, analyzes the traffic information in the ATM cells to count cells for each traffic kind, and writes the counted values in a memory 15. A CPU 12 performs a statistical information processing. A cell multiplexing demultiplexing circuit 13 multiplexes cells received from the respective subordinate parts 2-1 to 2-n and distributes cells received from traffic information measuring circuit 11 to the respective slave parts 2-1 to 2-n. A timer circuit 14 informs the CPU 12 of statistical information processing time in specific cycles.
