The details of the different modes are shown in Figure $2$

The period of each mode is defined as follows:

$\begin{array}{cc}\text{M}\text{o}\text{d}\text{e}& \text{P}\text{e}\text{r}\text{i}\text{o}\text{d}\\ \text{M}\text{o}\text{d}\text{e}0& 30seconds\\ \text{M}\text{o}\text{d}\text{e}1& 30seconds\\ \text{M}\text{o}\text{d}\text{e}2& 10seconds\\ \text{M}\text{o}\text{d}\text{e}3& 20seconds\end{array}$

Assume that the system runs at a $1Hz$ clock.

If you need to create a counter, then it should be designed structurally.

Project Deliverables:

All Verilog Files and test benches.

You need to create at least two testbenches:

$$ One that shows normal operation $($No pedestrians$).$

A test bench when a pedestrian pushes the button.

The test bench should display input$/$output values for every mode, as shown in the figure:

Mode $0$:$I=1,A1=0,A2=0,B=0,C=0$

Mode $1$: $I=0,A1=1,A2=,B=,C=1$

Mode $2$: $I=0,A1=1,A2=1,B=,C=0$

Mode $3$: $I=0,A1=0,A2=0,B=1,C=0$

The aim of this project is to design and simulate a traffic controller for a T$-$intersection. The controller has a single input and four outputs.

The intersection shown in Figure $1,$ has traffic coming from three different directions $(A,B,$ and $C).$

Traffic coming from directions $B$ and $C$ has a single traffic light each, while traffic coming from direction A has $2$ traffic lights as follows:

A$1$: Controls whether the traffic proceeds forward or not.

A$2$: Controls whether the traffic is allowed to go left or not.

In addition, the intersection has a push button $($I$)$ for pedestrians, when pressed it stops all traffic and allows pedestrians to cross.

Figure $1.$ Intersection Diagram

Design Requirements:

The traffic lights at this intersection operate with only two signals: $1$ for Green and $0$ for Red. $($i$.$e$.,$ no Yellow$).$

The traffic at this intersection has $4$ modes $($mode $0,$ mode $1,$ mode $2$ and mode $3).$

The sequence of traffic lights should follow $($mode $1,$ mode $2,$ mode $3,$ mode $1,$ mode $2....$ etc$)$

When the pedestrian button is pressed, the controller should transition to mode $0$ after completing the current mode time.

Once the time for mode $0$ has elapsed, the controller will resume with mode $1,$ mode $2,$ mode $3...$etc.
