EcoTrec—A Novel VANET-Based Approach to Reducing Vehicle Emissions

Abstract

Abstract-There are interdependent increases in vehicle numbers, vehicular traffic congestion, and carbon emissions that cause major problems worldwide. These problems include direct negative influences on people's health, adverse economic effects, negative social impacts, local environmental damage, and risk of catastrophic global climate change. There is a drastic need to develop ways to reduce these emissions and EcoTrec, presented in this paper, is one of these innovative approaches. EcoTrec is a vehicular ad hoc network-based vehicle routing solution designed to reduce vehicle carbon emissions without significantly affecting the travel times of vehicles. The vehicles exchange messages related to traffic and road conditions, such as average speed on the road, road gradient, and surface condition. This information is used to build a fuel efficiency model of the routes, based on which the vehicles are recommended to take more efficient routes. By routing vehicles more efficiently, the greenhouse emissions are reduced while also maintaining low traffic congestion levels. This paper presents results of extensive simulations, which show how EcoTrec outperforms other state-of-the-art solutions with different number of vehicles, vehicle penetration, and compliance rates, and when considering different real world road maps from Dublin and Koln.

Towards a distributed and infrastructure-less vehicular traffic management system

“…The assessment of the control channel is important since all the solutions analyzed apply the beaconing approach to share context-awareness information. In the experiments, the beacon transmission rate of 1Hz was set to all systems [4,7], including dEASY. Figure 7 depicts the performance results of the control channel at all the penetration rate possibilities.…”

“…Using the beaconing approach, a real-time traffic management system can collect raw data and extract useful information (or knowledge) about the traffic congestion in a region of interest. Several systems were designed and implemented to recommend an alternative route, in real-time, when an en-route event is detected [4,5,6,7].…”

Aplicando Redes Sociais Veiculares para Aprimorar o Gerenciamento da Mobilidade Urbana

“…Além disso, muitas aplicações de ATMS necessitam que os veículos periodicamente compartilhem os seus dados (floating car data) entre os veículos vizinhos ou com o servidor central e roadside unit (RSU). Através dessa operaçãoé possível criar o conhecimento sobre as condições de tráfego veicular [Wang et al 2016, Doolan and Muntean 2017, Pan et al 2017. Essa práticaé conhecida como beaconing e os dados trocados estão relacionados com a mobilidade do veículo tais como identificação do veículo, posição atual do veículo, velocidade, direção de deslocamento, entre outros.…”

“…Diferentes ATMSs foram projetados e implementados para superar o problema da baixa mobilidade urbana por meio do gerenciamento do tráfego veicular [Wang et al 2016, de Souza and Villas 2016, Doolan and Muntean 2017, Pan et al 2017. As soluções de [Doolan andMuntean 2017, Pan et al 2017] aplicam abordagem centralizada devidoà dificuldade de selecionar os veículos mais relevantes, em redes altamente dinâmicas, para as tarefas de detecção de congestionamento e sugestão de rotas alternativas. Além do mais, tais soluções esbarram na dificuldade de escalar os sistemas.…”

Adaptive Virtual RSU Scheduling for Scalable Coverage under Bidirectional Vehicle Traffic Flow

“…Much effort is required to deal with some issues in vehicular environments, such as the fast changing topology, the shortened intermittent connectivity, the unique set of applications, and the harsh propagation conditions [2][3][4]. Such distinguishing features demand the design of new networking solutions [5,6].…”
