Piezoelectric energy harvesting from raised crosswalk devices

Abstract

This paper presents the main characteristics of an experimental energy harvesting device that can be used to recover energy from the vehicular and pedestrian traffic. The use of a piezoelectric bender devices leads to a innovative approach to Henergy Harvesting. The study focuses on the definition and specification of a mechanical configuration able to transfer the vibration from the main box to the piezoelectric transducer. The piezoelectric devices tested is the commonly used monolithic piezoceramic material lead-zirconate-titanate (PZT). The experimental results estimate the efficiency of this device tested and identify the feasibility of their use in real world applications. The results presented in this paper show the potential of piezoelectric materials for use in power harvesting applications.

A Review on IEEE 802.11p for Intelligent Transportation Systems

“…With the advancement in wireless communication systems [4][5][6][7], the vision of vehicles communicating with each other and with other devices (e.g., mobile devices and roadside units) situated at various locations (e.g., roads and buildings) is becoming a reality [8][9][10]. For instance, an Internet-connected device (e.g., a mobile device/application) could notify drivers of the proximity of a bicyclist in the street or a pedestrian on a crosswalk [11][12][13][14][15], which could potentially reduce the number of pedestrian-related accidents. Such intelligent or smart safety systems have been referred to in the literature as vehicle-to-vehicle (V2V; or car-to-car (C2C)), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X; or car-to-everything (C2X)), vehicular ad hoc networks (VANETs), and so on [16][17][18].…”

An overview of big data analysis

“…IoT necessitates the development of many technologies currently designed by the leading companies and leads to a list of ever-growing advantages [11,12]. IoT applications cover many features, from health [13][14][15] to home automation [16][17][18][19], from transport [20][21][22][23][24] to security [25][26][27][28][29]. For instance, by spreading a set of sensors and processors, it is possible to control the windows, the temperature of the house, the lights, and other home appliances wirelessly [30,31].…”

V2X Communications Applied to Safety of Pedestrians and Vehicles

“…In most cases, pedestrians collide with vehicles due to the distraction caused by their interactions with smartphones [5] or other Internet of things (IoT) devices [6][7][8]. This circumstance determines a decrease in the attention threshold and causes hazardous neglects during the crossing of roads [9][10][11]. Although there are some traditional mechanisms to protect pedestrians from vehicles [12], most of these are fundamentally linked to a pedestrian's acoustic warning [13].…”
