No Traffic Jam by Student

No Traffic Jam technology provides an efficient, dynamic way to schedule traffic lights at an intersection. The goal of this adaptive system is to reduce traffic congestion on the roads caused by stopping the flow of traffic at a set of lights. This will decrease the amount of time drivers spending waiting in traffic by giving higher priority to busier roads.

No Traffic Jam model

The system tracks usage statistics on the roads in much the same way as a web server does in order to determine programatically which roads are busier and should therefore have priority. When implemented in a real-world system, these usage statistics should be stored for a much longer period of time and be divided by hour and day of the week. This would allow peak hour from 5pm-6pm on Wednesday to prioritise different roads than midday Thursday for instance.

Additionally the lights will only turn green on a road that contains traffic at that moment; this prevents time being wasted on routes with no momentary traffic.

The model we created uses 4 magnetic relays acting as sensors to detect the cars, these would be replaced by something more sofisticated sensors when the system is implemented on a larger scale. LED’s were used to represent the traffic lights, magnets attached to toy cars to activate the sensors and an Arduino board acted as the microcontroller for the system.

We hope this system provides a glimpse of the possibilities available for a more intelligent road network system.
