+# TrafficSafeAnalyzer
+
+一个基于 Streamlit 的交通安全分析系统，支持事故数据分析、预测模型、异常检测和策略评估。
+
+## 功能
+
+- 加载和清洗事故与策略数据（Excel 格式）
+- 使用 ARIMA、KNN、GLM、SVR 等模型预测事故趋势
+- 检测异常事故点
+- 评估交通策略效果并提供推荐
+
+## 安装步骤
+
+### 前提条件
+
+- Python 3.8+
+- Git
+- 可选：Docker（用于容器化部署）
+
+### 安装
+
+1. 克隆仓库：
+
+```bash
+git clone https://github.com/tongnian0613/TrafficSafeAnalyzer.git
+cd TrafficSafeAnalyzer
+```
+
+2. 创建虚拟环境（推荐）：
+
+```bash
+conda create -n trafficsa python=3.12 -y
+conda activate trafficsa
+pip install -r requirements.txt
+streamlit run app.py
+```
+
+3. 安装依赖：
+
+   (1) 基本安装（必需依赖）
+
+   ```bash
+   pip install streamlit pandas numpy matplotlib plotly scikit-learn statsmodels scipy
+   ```
+
+   (2) 完整安装（包含所有可选依赖）
+
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+   (3) 或者手动安装可选依赖
+
+   ```bash
+   pip install streamlit-autorefresh openpyxl xlrd cryptography
+   ```
+
+   (4) 运行应用：
+
+      ```bash
+      streamlit run app.py
+      ```
+
+## 依赖项
+
+列于 `requirements.txt`：
+
+```txt
+streamlit>=1.20.0
+pandas>=1.3.0
+numpy>=1.21.0
+matplotlib>=3.4.0
+plotly>=5.0.0
+scikit-learn>=1.0.0
+statsmodels>=0.13.0
+scipy>=1.7.0

+pytz>=2021.3
+openpyxl>=3.0.9
+xlrd>=2.0.1
+cryptography>=3.4.7
+openai>=2.0.0
+```
+
+## 配置参数
+
+- **数据文件**：上传事故数据（`accident_file`）和策略数据（`strategy_file`），格式为 Excel
+- **环境变量**（可选）：
+  - `LOG_LEVEL=DEBUG`：启用详细日志
+  - 示例：`export LOG_LEVEL=DEBUG`（Linux/macOS）或 `set LOG_LEVEL=DEBUG`（Windows）
+
+## 输入输出格式
+
+### 输入
+- **事故数据 Excel**：需包含 `事故时间`、`所在街道`、`事故类型` 列
+- **策略数据 Excel**：需包含 `发布时间`、`交通策略类型` 列
+
+### 输出
+- **预测结果**：CSV 文件（例如 `arima_forecast.csv`）
+- **图表**：HTML 文件（例如 `overview_series.html`）
+- **策略推荐**：文本文件（`recommendation.txt`）
+
+## 调用示例
+
+运行 Streamlit 应用：
+```bash
+streamlit run app.py
+```
+
+访问 http://localhost:8501，上传数据文件并交互分析。
+
+## 常见问题排查
+
+**问题**：`ModuleNotFoundError: No module named 'streamlit'`  
+**解决**：运行 `pip install -r requirements.txt` 或检查 Python 环境
+
+**问题**：数据加载失败  
+**解决**：确保 Excel 文件格式正确，检查列名是否匹配
+
+**问题**：`NameError: name 'strategy_metrics' is not defined`  
+**解决**：确保 `strategy_metrics` 函数定义在 `app.py` 中，且位于 `run_streamlit_app` 函数内
+
+## 日志分析
+
+- **日志文件**：`logs/app.log`（需在代码中配置 logging 模块）
+- **查看日志**：`tail -f logs/app.log`
+- **常见错误**：
+  - `ValueError`：检查输入数据格式
+  - `ConnectionError`：验证网络连接或文件路径
+
+## 升级说明
+
+- **当前版本**：v1.0.0
+- **升级步骤**：
+  1. 备份数据和配置文件
+  2. 拉取最新代码：`git pull origin main`
+  3. 更新依赖：`pip install -r requirements.txt --upgrade`
+  4. 重启应用：`streamlit run app.py`
+
+参考 `CHANGELOG.md` 查看版本变更详情。
