A Cooperative Intelligent Transportation System for Traffic Light Regulation Based on Mobile Devices as Floating Car Data (FCD)
This paper presents and analyzes a new Cooperative Intelligent Transportation System based on a simple concept: the use of information coming from the network of internet connected mobile devices to regulate traffic light systems. The new idea explored in this paper is a traffic light system with green cycles actuated by the information coming from mobile phone vehicle probes that would allow:
1) regulating traffic lights or offering information to drivers taking advantage of Floating Car Data (FCD);
2) convincing drivers to accept this system as beneficial and adopt it promptly and voluntarily becoming part of a successful cooperative system.
The idea presented in this paper is conceptually very simple: drivers interested in the service would install a mobile phone application on mobile devices with GNSS capabilities (such as GPS or Galileo system). This would allow the traffic light regulation system to know the position of subscribers and regulate traffic lights according to this. The fast and successful launch of the system would be guaranteed by the fact that, in the launch phase, the first drivers using the system would be given green priority on other drivers.
This paper carries on an analysis in a simulation framework to establish numerically what would happen at the launch of the system and when the subscriber base increases.
The Use of Adaptive Traffic Signal Systems Based on Floating Car Data
This paper presents a simple concept which has not been, up to now, thoroughly explored in scientific research: the use of information coming from the network of Internet connected mobile devices (on vehicles) to regulate traffic light systems. Three large-scale changes are going to shape the future of transportation and could lead to the regulation of traffic signal system based on floating car data (FCD): (i) the implementation of Internet connected cars with global navigation satellite (GNSS) system receivers and the autonomous car revolution; (ii) the spreading of mobile cooperative Web 2.0 and the extension to connected vehicles; (iii) an increasing need for sustainability of transportation in terms of energy efficiency, traffic safety, and environmental issues. Up to now, the concept of floating car data (FCD) has only been extensively used to obtain traffic information and estimate traffic parameters. Traffic lights regulation based on FCD technology has not been fully researched since the implementation requires new ideas and algorithms. This paper intends to provide a seminal insight into the important issue of adaptive traffic light based on FCD by presenting ideas that can be useful to researchers and engineers in the long-term task of developing new algorithms and systems that may revolutionize the way traffic lights are regulated.
