“…A lot of research has focused on energy harvesting speed bumps (EHSBs), electric ramps, and small wind harvesters. The conversion mechanism usually adopts rack and pinion mechanism [27][28][29][30], ball screw [31], cantilever system [32], torsion mechanism [33], hydraulic system [34], ratchet mechanism [35], linear generator [36][37][38], and other mechanisms or systems. Compared with the traditional power generation technology, the excitation of energy harvesting is usually random and discontinuous.…”

“…The hydraulic system can buffer the rolling impact force of the wheel, which makes the force of the power generation device more stable, and extends the service life of the EHSB. Guo and He [34] designed a hydraulic vibration energy harvesting system for speed bumps. Bench test is performed on the designed prototype, and the test confirmed that the energy harvesting system generates about 30 kJ at a time in 60 s. Ting et al [158] proposed a hydraulically driven road energy harvesting device arranged on a ramp with a required stroke of 30 mm, and their first-generation prototype had a total working efficiency of over 40%.…”

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.

“…Many studies show that researchers have designed and used hydraulic technology for energy harvesting for highways and speed bumps. [31][32][33] Nevertheless, when employing a road energy harvester (REH) system based on hydraulics, the equipment becomes less reliable, leading to elevated maintenance costs. Additionally, modifications to the pavement are necessary, leading to higher energy use and financial costs.…”

Due to the continuous increase of expressways and toll stations, there is a high potential for energy harvesting for sideway electronic devices. This article proposes a novel road energy harvester (REH) based on a crank‐shaft mechanism using bidirectional to unidirectional phenomenon to be installed on expressway toll stations. The REH contains four main components: the oscillation input from the suspension, the transfer unit, the generator unit, and the energy storage unit. The REH uses a crank‐shaft with spur gears as a mechanical motion rectifier and one‐way bearings, which can convert the oscillatory vibration into unidirectional generator rotation. In the energy storage module, electrical energy is being stored in supercapacitors. This study covers the design, modeling, and simulation of a crank‐shaft‐based energy harvester for harvesting suspension vibration energy. The energy harvester's dynamic modeling is used to assess the damping features. Simulated tests are conducted to demonstrate the proposed energy harvester's efficacy. Experiments are conducted, and the highest output voltage of 6.9 V peak is recorded for 5 mm/s with an efficiency of 53.66% which is enough for self‐powered applications at expressway toll booths such as traffic lights, caution lights, LED displays, sensors, etc.

“…During the "two sessions" in 2021, china report put forward the goals of "carbon peak" and "carbon neutrality". According to the data, China's coal consumption accounts for about 57 per cent of the country's total energy consumption [1][2]. The power industry is the area with the highest carbon emissions and coal use in China, and its carbon emissions have exceeded 40 per cent.…”

This paper presents an innovative design that aims to solve the problems of conventional speed bumps. The speed bump is capable of adjusting the cushioning strength in real time according to the speed of the vehicle and is equipped with a power generation facility. When a vehicle passes over the speed bump, the device converts the force exerted by the vehicle into electricity, which is stored in a battery. In low light conditions at night, the LED deceleration warning light provides a warning through the power generation facility, ensuring safe and comfortable driving. In addition, the speed bumps have a sunken design that reduces vehicle bumps, while powering the street lights at night through a sunken drive motor and generator. Each pass can generate 30KJ of electricity, and if 30,000 vehicles pass through each day, it can recover 5,000 watts of electricity per hour, reducing energy loss compared to traditional energy transmission methods. Modular design reduces the system price, low transformation threshold, can be applied to traditional speed bumps, reducing the cost recovery cycle to about one year, expanding the application scope.
