Real-time traffic data collection and dissemination from an Android Smartphone using proportional computation and freesim as a practical transportation system in Metro Manila

In this research, we present and study a practical Transportation System solution to the congestion concerns in a big city like Metro Manila Philippines. A Popular Mid-range Android Smartphone served as GPS sensor in a vehicle as traffic probe. Client application software was designed to generate GPS location updates with timestamps every second once it approached a designated roadway only. No additional client hardware and wireless infrastructure is needed since the system utilized the cellular system. FreeSim, a macroscopic/microscopic simulator, was used to automatically reflect traffic estimates through a browser for dissemination. Proportional computation was integrated into FreeSim which reflected traffic status in real time. The tests had an average error percentage of 2.08% and should open related researches for a true and practical intelligent transportation system in Metro Manila.
