Challenges And Opportunities

With the development of light emitting diodes (LEDs), the communication in visible light spectrum, visible light communication (VLC), becomes an alternative to the existing wireless technologies. Integration of VLC systems with intelligent transportation systems (ITS) can significantly improve many aspects of transportation and traffic. The use of unlicensed bandwidth and wider implementation of VLC LED lighting, both in infrastructure and in vehicles, provide an energy-efficient data transmission with sufficiently large data rates at low cost. The application of VLC systems is still at an early stage of the development. However, due to numerous advantages, the wider adoption of VLC systems is expected in near future. This chapter presents an analysis of the possibilities of VLC application in ITS scenarios. Main characteristics of VLC in ITS in terms of architecture, modulation and standardization are addressed. Some challenges and open issues are also emphasized.

Communication based on visible spectrum is a mode of communication wireless technology using the visible spectra by typical transmitters and receivers.Thistechnology, in developing Intelligent Transportation is a cost-reuction method. Currently Radio Frequency(RF)-based technology is used for road safety application and ripping out this method entirely by replacing it with VLC is not particularly feasible, so that the idea is retrofiting system that currently uses to work with combining both RF and VLC technologies. Here paper presents the specific technologies of wireless methodology for the Intelligent Transportation, which helps to minimize the occurrence of road accidents, optimize the road traffic and improve the safe of devices and roadside users. Application based on communication of vehicles, and vehicle to infrastructure has emerged the best solutions to improve traffic safety.It is on, visible light communication withbig potential ofsimple design for functional efficiency and large area distribution along with usage of Wi-Fi. The intention of this survey on a wide field, Intelligent Transportation Systems functioning with Wi-Fi and Li-Fi is discussed with its real time uses, technologies in communications

Available Information

With the rapid development of road traffic, real-time vehicle counting is very important in the construction of intelligent transportation systems (ITSs). Compared with traditional technologies, the video-based method for vehicle counting shows great importance and huge advantages in its low cost, high efficiency, and flexibility. However, many methods find difficulty in balancing the accuracy and complexity of the algorithm. For example, compared with traditional and simple methods, deep learning methods may achieve higher precision, but they also greatly increase the complexity of the algorithm. In addition to that, most of the methods only work under one mode of color, which is a waste of available information. Considering the above, a multi-loop vehicle-counting method under gray mode and RGB mode was proposed in this paper. Under gray and RGB modes, the moving vehicle can be detected more completely; with the help of multiple loops, vehicle counting could better deal with different influencing factors, such as driving behavior, traffic environment, shooting angle, etc. The experimental results show that the proposed method is able to count vehicles with more than 98.5% accuracy while dealing with different road scenes.

On The Road

Current vehicular systems require real-time information to keep drivers safer and more secure on the road. In addition to the radio frequency (RF) based communication technologies, Visible Light Communication (VLC) has emerged as a complementary way to enable wireless access in intelligent transportation systems (ITS) with a simple design and low-cost deployment. However, integrating VLC in vehicular networks poses some fundamental challenges. In particular, the limited coverage range of the VLC access points and the high speed of vehicles create time-limited links that the existing handover procedures of VLC networks can not be accomplished timely. Therefore, this paper addresses the problem of designing a vehicular VLC network that supports high mobility users. We first modify the traditional VLC network topology to increase uplink reliability. Then, a low-latency handover scheme is proposed to enable mobility in a VLC network. Furthermore, we validate the functionality of the proposed VLC network design method by using system-level simulations of a vehicular tunnel scenario. The analysis and the results show that the proposed method provides a steady connection, where the vehicular node is available more than 99% of the time regardless of the number of vehicular nodes on this network. Additionally, the system is able to achieve a Frame-Error-Rate (FER) performance lower than 10−3.
