  • Allows the traffic diversification by configuring the physical attributes (name, acceleration, deceleration, maximum speed, color) and at the same time behavioral attributes (sigma parameter)
  • Future work: - taking into account pedestrian traffic - including of a system based on recommendation to offer the drivers suggestion regarding the best route - implementing of a module for mobile and wireless devices, PDA
  • Distributed traffic management system
