Traffic Light Circuit usid 4017

This is a simple design of a traffic light project that uses 4017 IC. This circuit demonstrate a simple two traffic light. 

The clock source is not included in the diagram but you can use 555 astable circuit as an oscillator.

The time of switching of the lights are in proportions.

3/10 for green

2/10 for yellow 

5/10 for stop

In the schematic, a traffic light model was used in the simulation. But in the actual, you can implement it using LEDs.

Here is the schematic of the traffic light circuit:
