以下是一个简单的 MATLAB 代码,用于绘制十字路口四相位系统信号配时图:
```matlab
% 定义信号灯周期时长
cycle_length = 90;
% 定义每个相位的绿灯时长
green_time = [30, 30, 30, 30];
% 定义每个相位的黄灯时长
yellow_time = [3, 3, 3, 3];
% 定义每个相位的红灯时长
red_time = cycle_length - green_time - yellow_time;
% 定义相序数组
phase_sequence = [1, 2, 3, 4];
% 绘制信号灯配时图
figure;
hold on;
% 绘制相位1
rectangle('Position', [0, 0, green_time(1), 1], 'FaceColor', 'g');
rectangle('Position', [green_time(1), 0, yellow_time(1), 1], 'FaceColor', 'y');
rectangle('Position', [green_time(1) + yellow_time(1), 0, red_time(1), 1], 'FaceColor', 'r');
% 绘制相位2
rectangle('Position', [0, 2, red_time(2), 1], 'FaceColor', 'r');
rectangle('Position', [red_time(2), 2, yellow_time(2), 1], 'FaceColor', 'y');
rectangle('Position', [red_time(2) + yellow_time(2), 2, green_time(2), 1], 'FaceColor', 'g');
% 绘制相位3
rectangle('Position', [2, 1, red_time(3), 1], 'FaceColor', 'r');
rectangle('Position', [red_time(3), 1, yellow_time(3), 1], 'FaceColor', 'y');
rectangle('Position', [red_time(3) + yellow_time(3), 1, green_time(3), 1], 'FaceColor', 'g');
% 绘制相位4
rectangle('Position', [1, 3, green_time(4), 1], 'FaceColor', 'g');
rectangle('Position', [green_time(4), 3, yellow_time(4), 1], 'FaceColor', 'y');
rectangle('Position', [green_time(4) + yellow_time(4), 3, red_time(4), 1], 'FaceColor', 'r');
% 设置图形属性
axis([0 cycle_length 0 4]);
axis off;
% 添加相序标签
text(green_time(1)/2, 0.5, '1');
text(cycle_length - red_time(2)/2, 2.5, '2');
text(cycle_length - red_time(3)/2 + 2, 1.5, '3');
text(green_time(4)/2 + 1, 3.5, '4');
```
运行此代码将绘制一个类似于以下图像的信号灯配时图:
