Sensor Based Traffic System With Pedestrians In Mind

The number of road injury fatalities is expected to double by 2030 in low- and medium-income countries affecting mainly pedestrians and cyclists. The paper proposes a relatively inexpensive sensor-based traffic signals system based on traffic flow and pedestrians' movements. The system uses ontologies to allow emergency vehicle communication and expedited arrival. Furthermore, the system generates alerts when a possible pedestrian collision is projected. The paper contribution is including the semantics associated with the pedestrian's density, and emergency vehicles needs to optimize the traffic flow. Furthermore, it uses ultrasonic sensors to allow for less expensive implementation.
