Abstract

Intelligent Transportation Systems (ITS) rely on Inter-Vehicle Communication (IVC) to streamline the operation of vehicles by managing vehicle traffic, assisting drivers with safety and sharing information, as well as providing appropriate services for passengers. Traffic congestion is an urban mobility problem, which causes stress to drivers and economic losses. In this context, this work proposes a solution for the detection, dissemination and control of congested roads based on inter-vehicle communication, called INCIDEnT. The main goal of the proposed solution is to reduce the average trip time, CO emissions and fuel consumption by allowing motorists to avoid congested roads. The simulation results show that our proposed solution leads to short delays and a low overhead. Moreover, it is efficient with regard to the coverage of the event and the distance to which the information can be propagated. The findings of the investigation show that the proposed solution leads to (i) high hit rate in the classification of the level of congestion, (ii) a reduction in average trip time, (iii) a reduction in fuel consumption, and (iv) reduced CO emissions

Highlights

In the last decade, the use of mobile devices, ad hoc communication and ubiquitous computing have changed people’s lives, by allowing the exchange of information anywhere and anytime
These results can be explained by the fact that the proposed protocol allows vehicles within the Area of Interest (AoI) to store and carry the data packet around the network until the vehicle reaches a new one that has not received the message yet
When there were 5000 vehicles/km2 and OVMT, INCIDEnT obtained a reduction of approximately 35% and when compared with the protocol that is closest to our proposal, it obtained a reduction of 15%

Summary

Introduction

The use of mobile devices, ad hoc communication and ubiquitous computing have changed people’s lives, by allowing the exchange of information anywhere and anytime. It is expected that the use of mobile communications in vehicles will be a reality in a few years’time, since the automobile industry, governments and universities around the world are devoting resources to creating a safe transportation system [1,2,3,4]. Vehicular Ad Hoc Networks (VANETs) or ‘vehicular networks’, are a special type of mobile ad hoc networks, where. Increasing Intelligence in Inter-Vehicle Communications to Reduce Traffic Congestions
