Abstract With the rapid development of road networks, various traffic safety issues have become endless. To solve problems, a multi‐mode triboelectric nanogenerator(M‐TENG) composed roller‐based TENG, turnplate‐based and vertical separation‐based TENG is proposed. The M‐TENG can be applied to harvest wind energy mechanical vibrational generated by moving vehicles on ordinary roads or beside bridges provide power for warning devices signal sensors. In terms harvesting, shows an excellent conversion capability. For respond well frequency range (1–40 Hz) bridge vibration in actual environment produce good output. Thus, due above outputs, successfully caution lights commercial LED strips, achieving effect. Additionally, also send RF signals after charging management unit circuit 5 min when simulating natural environment. Based aforementioned wide applications, not only demonstrates its harvesting capability but that it has huge potential field transportation.
