For the current situation of urban road reconstruction in China, this paper proposes a single intersection multi-segment timer traffic signal controller based on a single-chip microcomputer with a GPS timing function. The system receives time from the GPS satellite, and uses solar panels for a power supply, so the multi-controller could run simultaneously without connections, greatly reducing the cost. The use of segmented design within the system could set multiple time periods with different parameters in order to meet real-time traffic flow changes. The signal controller software is equipped with a password lock and short-circuit protection. After testing, the GPS module and signal controller had good integration and stable operation. This program had a high practical significance and application value.
