On the impact of virtual traffic lights on carbon emissions mitigation

  1. 1. On the Impact of Virtual Traffic Lights On Carbon Emissions Mitigation Abstract: The monitoring and control of city traffic is becoming a major problem in many countries. With the ever increasing number of vehicles on the road, the Traffic Monitoring Authority has to find new methods of overcoming such a problem. Considering that the transport sector is responsible for an increasingly important share of current environmental problems, we look at Intelligent Transportation Systems (ITS) as a feasible means of helping in solving this issue. In particular, we evaluate the impact in terms of Carbon Dioxide (CO2) emissions of Virtual Traffic Light (VTL), which is a recently proposed infrastructure less traffic control system solely based on Vehicle-to-Vehicle (V2V) communication. We propose a traffic information service for which traffic data are collected over ad-hoc networks from neighbor vehicles, processed to minimize the data size, and eventually provided to its destination. The proposed scheme simply relies on the existing navigation systems in vehicles and wireless communication devices for vehicle-to-vehicle communication, rather than on a separately established server. It allows collecting and analyzing traffic status of large areas without incorporating separated monitoring systems, e.g., probe cars and enables to provide accurate traffic information to drivers in timely manner. Existing System: Present Traffic Light Controllers is based on microcontroller and microprocessor. These TLC have limitations because it uses the pre-defined hardware, which is functioning according to the program that does not have the flexibility of modification on real time basis. There is no Emission test is undertaken on the traffic congestion. Due to the fixed time intervals of green, orange and red signals the waiting time is more and car uses more fuel.
  2. 2. Proposed System: This project “Virtual traffic light on Carbon Emission Mitigation” makes use of Networks along with Embedded Technology. The main objective for this project is to design a program and implement hardware of virtual traffic light system suitable for real life implementations. This project also aims to design a safe and efficient traffic flow, to assign the right way and minimizes the delay or waiting time at road. The information about congestion on roads is intimated through wireless communication. The Service scenario is follows that vehicles in two directions may intimate the traffic information. The CO2 sensor we used in our system to sense the Carbon di-oxide emissions from the vehicles. This information’s is transmitted to the other vehicles through the Zigbee wireless communication. Based on this other vehicles in the other direction will receive the information. The vehicle in the Traffic signal in one direction will transmit the CO2 level. On the other side traffic signal the vehicle transmit the CO2 level. The traffic light indication will given in the appropriate directions. The status will be shown in LCD.
