This paper deals with the development of a software tool to evaluate road pavement energy harvesting systems technically and economically, as well as performing cost benefit analysis for the application of this type of energy generation solution as the energy source for different applications. The software also allows the user to perform a sensitivity analysis by selecting a key variable and defining its different values. Some case studies are also presented to demonstrate the software application and how it can be used to evaluate this technology.

Research into energy harvesting technologies has increased considerably in recent years. The particular case of energy harvesting on road pavements is a very recent area of research, with different technologies having been developed for this purpose. However, none of them has presented high conversion-efficiency rates nor technical or economic viability. Looking at other renewable energy technologies, the inclusion of not only electrical but also, in some cases, mechanical energy-storage units has led to an increase in global efficiency and, consequently, viability. This paper deals with the technical study of the integration of a mechanical energy-storage system in a road pavement hydraulic energy-harvesting device, in order to evaluate the impact on global efficiency. The main goal is to quantify the efficiency of the energy storage as well as the overall efficiency of the system, including the harvesting, transmission and conversion-efficiency rate, comparing it to scenarios where no storage system is used. Finally, the conclusions on the performance of each system are presented.

A new pavement energy harvest system was developed in Portugal by the Waydip Company in collaboration with the Pavement Mechanics Laboratory of the University of Coimbra. Recently, the system has been optimised and a significant improvement in energy generation has been achieved. Moreover, a 25-module pilot plant has been installed in the entrance to a shopping mall and tested. During a 4-month period it generated more than 10·7 MJ (3·0 kWh). This paper updates the earlier reports on this topic.

With the growing need for alternative energy sources, research into energy-harvesting technologies has increased considerably in recent years. The particular case of energy harvesting on road pavements is a very recent area of research, with different technologies having been developed in recent years. However, none of them have presented high conversion efficiencies nor technical or economic viability. This paper deals with the technical study of existing road pavement energy–harvesting solutions using electromechanical systems to transmit energy from the device surface to an electrical generator and the development of a new mechanical system to implement on such devices. The main goal is to quantify the energy harvesting, transmission, and conversion efficiency of the new system and compare it with the existing systems. Conclusions about each system’s efficiency and the maximum theoretical efficiency of the proposed system are presented.

Purpose This paper aims to deal with the development of a software tool to simulate and study vehicle – road interaction (VRI) to quantify the forces induced and energy released from vehicles to the road pavement, in different vehicle motion scenarios, and the energy absorbed by the road surface, speed reducers or a specific energy harvester surface or device. The software tool also enables users to quantify the energetic efficiency of the process. Design/methodology/approach Existing software tools were analysed and its limitations were identified in terms of performing energetic analysis on the interaction between the vehicle and the road pavement elements, such as speed reducers or energy harvest devices. The software tool presented in this paper intends to overcome those limitations and precisely quantify the energy transfer. Findings Different vehicle models and VRI models were evaluated, allowing to conclude about each model precision: bicycle car model has a 60 per cent higher precision when compared with quarter-car model, and contact patch analysis model has a 67 per cent higher precision than single force analysis model. Also, a technical study was performed for different equipment surface shapes and displacements, concluding that these variables have a great influence on the energy released by the vehicle and on the energy harvested by the equipment surface. Originality/value The developed software tool allows to study VRI with a higher precision than existing tools, especially when energetic analyses are performed and when speed reduction or energy harvesting devices are applied on the pavement.

This paper describes an innovative pavement energy harvest system, called Waynergy Vehicles, developed in Portugal by Waydip in partnership with the Pavement Mechanics Laboratory of the University of Coimbra. This system was installed in a university campus road pavement, which allowed the testing of a prototype. During a peak hour, between 1ṡ00 p.m. and 2ṡ00 p.m., the system was able to generate 37 800 J or 10ṡ5 Wh. The electrical energy generated by several modules of the system located, for example, in speed humps and speed bumps, can be used not only to charge batteries for electric vehicles, but also for general consumption through injection into the electricity grid or direct use by electrical equipment, such as public lighting, traffic lights and outdoor advertising.

This paper describes a new pavement energy harvest system developed in Portugal by the Waydip Company with the collaboration of the pavement mechanics laboratory of the University of Coimbra. The electric energy generated by the Waynergy system for people during 1 h was 525 J or 0·15 W·h. It is expected that the Waynergy system for vehicles could generate substantial electrical energy, which can be used not only to charge batteries for electric vehicles, but also for general consumption through injection into the electricity grid or direct use in electrical equipment, such as traffic lights, public lighting and outdoor advertising.
