Design and Implementation of Portable Smart Wireless Pedestrian Crossing Control System

Abstract

Walking is a daily activity that requires an appropriate crosswalk as a key part of the provision of safe transportation infrastructure. In this paper, we design and develop a portable smart wireless control system for pedestrian crossing areas to manage the traffic automatically and allow the pedestrian, like school children, to cross the road safely and effortlessly. The system incorporates the concept of smart sensing to detect the presence of pedestrians and in turn, automatically controls the crosswalk traffic lights. The system composes of two Arduino microcontrollers, two infrared PIR motion sensors, and a bidirectional wireless communication link based on Bluetooth for mitigating wiring installation and transmitting the signal among traffic light units on both roadsides. The system is fabricated and implemented as a portable LED-based traffic light testbed. The developed system is tested and validated in a real environment with a 6 m road width on the university campus. According to the obtained results, the system worked effectively and fulfilled the design criteria where the communication between both sides lights is successfully functioning and the PIR sensors can accurately detect the existence of pedestrians. The developed system is cost-effective, energyefficient, easy to install, and maintenance-free.

Client-Centric Access Device Selection for Heterogeneous QoS Requirements in Beyond 5G IoT Networks

“…The devices also tend to transmit the raw sensing data to its manufacturer for detailed data mining inside the remote data center [26]. Some other use cases entail explicit requirement of transmitting sensor data over the communication network, such as [27] for baby monitoring empowering smart cradle, and [28] for a pedestrian crossing control system. Assistance required from communication networks for few applications has hard QoS bounds to ensure the infrastructure's safety and security, such as mentioned in [29] for smart grids.…”

Handover Parameters Optimisation Techniques in 5G Networks

“…The HO procedure consumes significant system resources, and the intended UE may experience substantial system delays and performance deterioration. Therefore, HO should not randomly occur [ 17 , 18 ]. Additionally, the use of mm waves in 5G technology is the dominant factor that impacts mobility [ 19 , 20 ].…”

Performance Enhancement of SCM/WDM-RoF-XGPON System for Bidirectional Transmission With Square Root Module

“…In upstream transmission, the data is sent from network units on the receiver side to the transmitter's optical terminal. The process is simultaneously reversed in the downstream direction [9][10][11].…”
