The invention relates to a traffic information measurement and control system and method based on electret pressure sensors. The system comprises a signal generation module which is used for generating an electric signal, a signal acquisition module which is used for converting the generated alternating-current electric signal into a direct-current electric signal and carrying out analog-to-digital conversion, a signal analysis module which is used for storing data obtained through the conversion of the signal acquisition module to a PC terminal, analyzing the data and uploading the data to acloud database through the PC terminal, and an information management module which is used for managing the cloud database, judging vehicle driving information and transmitting the information to a user side. An electret pressure sensor array is placed on the road surface, special construction is not needed, measurement positions can be flexibly determined, use is convenient, and the influence ofsurrounding environment is small; with the electret pressure sensors adopted, the conversion from mechanical energy to electric energy can be realized, and stability is very good.
