 3. Open `http://localhost:8501` in your browser. The home page should load without import errors.
 
+## 5. Run with Docker (optional)
+
+If you prefer an isolated container build, use the included `Dockerfile`:
+
+```bash
+docker build -t trafficsafeanalyzer .
+docker run --rm -p 8501:8501 trafficsafeanalyzer
+```
+
+To work with local data, mount the host folder containing Excel files:
+
+```bash
+docker run --rm -p 8501:8501 \
+  -v "$(pwd)/sample:/app/sample" \
+  trafficsafeanalyzer
+```
+
+The container exposes Streamlit on port 8501 by default. Override configuration via environment variables when needed, for example `-e STREAMLIT_SERVER_PORT=8502`.
+
 ## Troubleshooting tips
 
 - **Missing package**: Re-run `pip install -r requirements.txt`.

+### 使用 Docker 运行
+
+项目根目录已经包含 `Dockerfile`，无需额外配置即可容器化运行：
+
+```bash
+# 构建镜像
+docker build -t trafficsafeanalyzer .
+
+# 以临时容器方式启动
+docker run --rm -p 8501:8501 trafficsafeanalyzer
+```
+
+运行后访问 `http://localhost:8501` 即可。若需加载主机上的数据文件，可通过挂载方式注入：

+  trafficsafeanalyzer
+```
+
+容器内默认启用了示例 AI 凭据与 Streamlit Headless 模式，如需调整可在 `docker run` 时追加环境变量（例如 `-e STREAMLIT_SERVER_PORT=8502`）。
