Virtual Traffic Light Implementation on a Roadside Unit over 802.11p Wireless Access in Vehicular Environments

Abstract

Blind intersections have high accident rates due to the poor visibility of oncoming traffic, high traffic speeds, and lack of infrastructure (e.g., stoplights). These intersections are more commonplace in rural areas, where traffic infrastructure is less developed. The Internet of Vehicles (IoV) aims to address such safety concerns through a network of connected and autonomous vehicles (CAVs) that intercommunicate. This paper proposes a Road-Side Unit-based Virtual Intersection Management (RSU-VIM) over 802.11p system consisting of a Field-Programmable Gate Array (FPGA) lightweight RSU that is solar power-based and tailored to rural areas. The RSU utilizes the proposed RSU-VIM algorithm adapted from existing virtual traffic light methodologies to communicate with vehicles over IEEE 802.11p and facilitate intersection traffic, minimizing visibility issues. The implementation of the proposed system has a simulated cloud delay of 0.0841 s and an overall system delay of 0.4067 s with 98.611% reliability.

Multi-Objective Message Routing in Electric and Flying Vehicles Using a Genetics Algorithm

“…On the other hand, it is always possible to consider the original hop count-based routing scheme which not only ensures the minimum number of hops in a route but also results in a faster route selection [ 9 ]. Nevertheless, several existing solutions have tried utilizing SDN or a multi-objective routing for ground vehicles [ 10 , 11 , 12 ]. Moreover, routing in UAVs which considers metrics such as charging stations, VANET supporting networks, and trajectory-based systems has also been proposed [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

“…Ref. [8] presents a solution based on vehicular communications for blind intersections with high accident rates due to the poor visibility of oncoming traffic. For this purpose, a Road-Side Unit-based Virtual Intersection Management over 802.11p system is used, and it is specifically prepared for rural areas.…”
