How i can add a car image to yellow boxes and at y coordinate 4,5,6 a road image? (Sorry i have low vocabulary of English).

close all;
clc;

loop = 200;
r = 9;
c = 20;
carOccuranceMidWay = 0.05; %0-1
carMoveMidWay = 0.4; %0-1
carMoveFastWay = 0.7; %0-1
carMoveSlowWay = 0.2; %0-1

% define grid
x = zeros(r, c);

figure;
%  x(5,1) = 1;
%
for i = 1:loop
    
    for j = 1:c - 1    
        if(rand <= carOccuranceMidWay &&  x(5,1) == 0)
            x(5,1) = 1;    
            
        end
        
        % car exit from highway
        if(x(5,c - 1) == 1)  %For centerline
            x(5,c - 1) = 0;
        end
        
        if(x(4,c - 1) == 1)   %For FastLane
            x(4,c - 1) = 0;
        end
        
        if(x(6,c - 1) == 1)   %For SlowLane
            x(6,c - 1) = 0;
        end
        
        % car move
        
        if(x(5, j) == 1 && x(5, j + 1) == 0)        % transition rules #1 for centerlane movement 
            if(rand <= carMoveMidWay)
                x(5, j ) = 0;           
                x(5, j  + 1) = 1;

        if(x(5, j) == 1 && x(5, j + 1) == 1 && x(6,j)== 0)        % transition rules #3 for transition to SlowLane
            if(rand <= carMoveMidWay)
                x(5, j ) = 0;

            end
        end

        % Display grid
        pause(0.01);
        
    end                             % Pause for 0.01 s

Hi Abdul,

The “imagesc” function can only plot heatmaps, to add roads and cars to your animation you can explore the “plot(scenario)” functionality of MATLAB used for plotting driving scenario which is the case.

You can also investigate the “vehicle” object which is used to add vehicle to driving scenario.

Here are the links to the documentation for the above-mentioned functionalities:

https://www.mathworks.com/help/driving/ref/drivingscenario.vehicle.html

Hope it helps.
