The intelligent traffic sensing system for a T-intersection of claim 1, wherein: the base plate is provided with strip-shaped mounting grooves which are uniformly distributed along the length direction of the base plate at intervals, pressing blocks which are embedded in the strip-shaped mounting grooves and are consistent with the groove-shaped size of the base plate are arranged in the strip-shaped mounting grooves, a plurality of elastic connecting blocks which are used for being connected with the pressing blocks are distributed on the bottom surfaces of the strip-shaped mounting grooves at intervals, and the contact sensor and the gravity detector are arranged between the pressing blocks and the bottom surfaces of the strip-shaped mounting grooves and triggered by pressing down of the pressing blocks.
3. The intelligent traffic sensing system for a T-intersection of claim 2, wherein: the base plate is formed by connecting multiple sections, and two adjacent sections are connected through an inserting block and an inserting groove.
4. The intelligent traffic sensing system for a T-intersection of claim 2, wherein: the width of the pressing block and the strip-shaped mounting groove is 1-5 cm.
5. The intelligent traffic sensing system for a T-intersection of claim 2, wherein: the signal lamp mounting grooves are formed in the base plate at intervals along the length direction of the base plate, and the signal lamp strips are embedded in the signal lamp mounting grooves.
