The invention discloses a traffic information data collection system and method based on an ARM processor. The data collection system comprises an upper computer module, an interface module, an ARM processor module, a CAN transceiver module and a data collection module. The upper computer is used for configuring radar state parameters, sending processing information and receiving and storing collected data. The interface module is used for communication and data transceiving between the upper computer and the ARM processor module; and the ARM processor module completes data receiving, transmission and processing. The method comprises the following steps: performing pipeline processing on radar data transmitted through a CAN bus protocol by adopting a multi-thread concurrent model and a double-buffer processing mode, and finally transmitting a processed data result back to a data background through a network cable for comprehensive processing. According to the invention, a driving program based on an ARM core processor is designed autonomously, and the original position, speed, signal intensity and other information of a traffic target are collected efficiently and quickly by usinga CAN bus protocol.
