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

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

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.

EXISTING SYSTEM:

  • Existing scheme considered receiving information on traffic over FM radio and inspected existing flaws in navigation systems and ways of addressing them. The paper discussed issues such as gullibility errors where the driver follows the automotive navigation’s directions even when they do not make sense. Also it noted that drivers do not always follow the advice of the navigation system.
  • The paper suggests giving the driver a number of choices and indicating the advantages of each choice. This is a good idea as machines are not always capable of judging the advantages of some concepts and different users will have different preferences, e.g. some drivers may not like driving a certain roads.

DISADVANTAGES OF EXISTING SYSTEM:

  • Traffic congestion also causes a lot of time-related stress for people who waste time in traffic.
  • RSUs are a very expensive wayto improve connectivity, using the store and carry approach isslow for messages to reach all the vehicles and increasing thetransmission power will improve the connectivity slightly onlyand scaling is very limited.
  • An obvious limitation is that DNA does notconsider road length over road speed in order to get the timevehicles take to traverse a road segment.

PROPOSED SYSTEM:

  • This paper presented EcoTrec, a traffic and road characteristic aware VANET-based routing solution for reducing carbon emissions.The EcoTrec architecture, whose major components are a Vehicle Model, a Road Model and a Traffic Model.
  • The vehicle model is built and updated by each individual vehicle, using information from the GPS sensors, speedometer and accelerometer. The vehicle’s local traffic conditions are used to create and maintain the Traffic Model. The Road Model is maintained at a central Server and is updated with information on the nearby roads. The data is exchanged using IEEE 802.11p.

ADVANTAGES OF PROPOSED SYSTEM:

  • Simulation-based testing compared the proposed solutionwith different penetration and compliance rates against realvehicular traffic data from cities of Dublin and Koln, and algorithmsproposed by Dijkstra and Sommer. In terms of the percentageof vehicles which reached their destinations, EcoTrecoutperformed the real-life situation and Sommer algorithm by15% and 17% respectively, and was very similar in performanceto applying the Dijkstra shortest path solution.
  • In terms of emissions, EcoTrec outperformed the real-lifecase, Dijkstra and Sommer algorithms by 21%, 19%, and 12%,respectively.
