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, energy-efficient, easy to install, and maintenance-free.
Highlights
Walking is considered as the most basic and simple mode of transportation
Each unit will be placed on one side of the pedestrian crossing area
The Passive Infrared (PIR) sensor will give false signal because it can detect the presence of pedestrian at far from the traffic light
Summary
Any person not riding a vehicle is known as a pedestrian. As compared to other road users, pedestrians, who are defined as vulnerable road users, are not related to any vehicle mode [1]. They are unprotected (more exposed) during interaction with road traffic system, especially when involved in road accidents unlike other road users inside vehicles with protection ‘‘shell’’, as well as motorcyclists and cyclists with compulsory/recommended crash helmets. At the road crossing area, pedestrians are typically assisted in road crossing by using a manually pedestrian crossing control system, which may comprise lighted signs (‘‘WALK’’, ‘‘DON’T WALK’’), integrated to the existing traffic lights [2]
