“…Moure et al [24] integrated a cymbal PEH into the asphalt pavement, energy densities in the range of 40-50 MW h m −2 can be obtained at 100 m of road (use of 30 000 cymbals), which could account for more than 65 MW h in a year. Jeon et al [136] proposed a lever-type PEH with a deformation-guiding mechanism, they charged a 0.08 F supercapacitor up to 5.09 V in 170 min. Shin and Jung et al [137,138] proposed a piezoelectric polymer-based road energy harvesting module using bridge displacement amplification mechanism to produce up to 16.5 W m −2 of power output under a small vertical displacement of 2.5 mm.…”

The concept of green and sustainable development is driving the convergence of transportation systems and energy technologies. New energy harvesting technology is an important way of the development in the green intelligent transportation system. Comparing with the power supply via batteries or cables, it has the advantages of convenient, sustainable, green and low carbon to harvest mechanical energy from the traffic environment and convert it into electrical energy to power the widely distributed small electromechanical systems. There are many studies on mechanical energy harvesting in traffic environment, few of them have comprehensively discussed these studies and their applications in the intelligent transportation. This paper first outlines the principles, methods, and energy management strategies of the mechanical energy harvesting in the traffic environment. The advantages, disadvantages, and applicability of various energy harvesting technologies are comprehensively and systematically analyzed from vehicle and road dimensions. The applications of energy harvesting technology was discussed includes: self-powered traffic control, self-powered vehicle-road collaboration and self-powered health monitoring of traffic infrastructure. Finally, the challenges and prospects of mechanical energy harvesting technology and applications in the traffic environment are discussed. Mechanical energy harvesting in traffic environment has broad application prospects in intelligent transportation, while improving the output power and reliability of the energy harvesting system is the key to its wide application in intelligent transportation systems.

In this study, we designed a full-scale road piezoelectric energy harvester (FPEH) and performed field tests to evaluate its electrical performance under various traffic loads. Based on the open-circuit voltage waveform of the FPEH, its electrical output law was established considering different axle loads and vehicle speeds. Two off-board circuits were designed for different applications of the FPEH. Circuit (1) rectifies 192 transducer units separately and then connects them in parallel; at a resistance load of 0.4 kΩ, vehicle speed of 60 km/h, and axle load of 1295 kg, this circuit generated a maximum output of 42 V, 104 mA, and 4338 mW. Circuit (2) rectifies eight transducer units separately and then connects in parallel to form a total of 24 groups; this circuit can be used to identify the wheel track and wheel position of the vehicle, it was also used to determine the horizontal transfer law of the vehicle vibration energy on the road surface. The findings obtained herein provide a good foundation for the application of road piezoelectric power generation technology.
