# Repository Guidelines
|
|
||||||
|
|
||||||
## Project Structure & Module Organization
|
|
||||||
- Source: `app.py` (Streamlit UI, data processing, forecasting, anomaly detection, evaluation).
|
|
||||||
- Docs & outputs: `docs/`, `overview_series.html`, `strategy_evaluation_results.csv`.
|
|
||||||
- Samples: `sample/` for example data only; avoid sensitive content.
|
|
||||||
- Meta: `requirements.txt`, `readme.md`, `LICENSE`, `CHANGELOG.md`.
|
|
||||||
|
|
||||||
## Build, Test, and Development Commands
|
|
||||||
- Create env: `python -m venv .venv && source .venv/bin/activate` (or follow conda steps in `readme.md`).
|
|
||||||
- Install deps: `pip install -r requirements.txt`.
|
|
||||||
- Run app: `streamlit run app.py` then open `http://localhost:8501`.
|
|
||||||
- Export artifacts: charts save as HTML (Plotly); forecasts may be written to CSV as noted in `readme.md`.
|
|
||||||
|
|
||||||
## Coding Style & Naming Conventions
|
|
||||||
- Python ≥3.8; 4-space indentation; UTF-8.
|
|
||||||
- Names: functions/variables `snake_case`; classes `PascalCase`; constants `UPPER_SNAKE_CASE`.
|
|
||||||
- Files: keep scope focused; use descriptive output names (e.g., `arima_forecast.csv`).
|
|
||||||
- Data handling: prefer pandas/NumPy vectorization; validate inputs; avoid global state except constants.
|
|
||||||
|
|
||||||
## Testing Guidelines
|
|
||||||
- Framework: pytest (recommended). Place tests under `tests/`.
|
|
||||||
- Naming: `test_<module>.py` and `test_<behavior>()`.
|
|
||||||
- Run: `pytest -q`. Focus on `load_and_clean_data`, aggregation, model selection, and metrics.
|
|
||||||
- Keep tests fast and deterministic; avoid large I/O. Use small DataFrame fixtures.
|
|
||||||
|
|
||||||
## Commit & Pull Request Guidelines
|
|
||||||
- Messages: concise, present tense. Prefixes seen: `modify:`, `Add`, `Update`.
|
|
||||||
- Include scope and reason: e.g., `modify: update requirements for statsmodels`.
|
|
||||||
- PRs: clear description, linked issues, repro steps/screenshots for UI, and notes on any schema or output changes.
|
|
||||||
|
|
||||||
## Security & Configuration Tips
|
|
||||||
- Do not commit real accident data or secrets. Use `sample/` for examples.
|
|
||||||
- Optional envs: `LOG_LEVEL=DEBUG`. Keep any API keys in environment variables, not in code.
|
|
||||||
- Validate Excel column names before processing; handle missing columns/rows defensively.

|

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||||
|
|
||||||
|
## Build and Run Commands
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Install dependencies
|
||||||
|
pip install -r requirements.txt
|
||||||
|
|
||||||
|
# Run the Streamlit application
|
||||||
|
streamlit run app.py
|
||||||
|
|
||||||
|
# Run tests (if tests/ directory exists)
|
||||||
|
pytest -q
|
||||||
|
```
|
||||||
|
|
||||||
|
## Architecture Overview
|
||||||
|
|
||||||
|
This is a Streamlit-based traffic safety analysis system with a three-layer architecture:
|
||||||
|
|
||||||
|
### Layer Structure
|
||||||
|
|
||||||
|
```
|
||||||
|
app.py (Main Entry & UI Orchestration)
|
||||||
|
↓
|
||||||
|
ui_sections/ (UI Components - render_* functions)
|
||||||
|
↓
|
||||||
|
services/ (Business Logic)
|
||||||
|
↓
|
||||||
|
config/settings.py (Configuration)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Data Flow
|
||||||
|
|
||||||
|
1. **Input**: Excel files uploaded via Streamlit sidebar (事故数据 + 策略数据)
|
||||||
|
2. **Processing**: `services/io.py` handles loading, column aliasing, and cleaning
|
||||||
|
3. **Aggregation**: Data aggregated to daily time series with `aggregate_daily_data()`
|
||||||
|
4. **Analysis**: Various services process the aggregated data
|
||||||
|
5. **Output**: Interactive Plotly charts, CSV exports, AI-generated reports
|
||||||
|
|
||||||
|
### Key Services
|
||||||
|
|
||||||
|
| Module | Purpose |
|
||||||
|
|--------|---------|
|
||||||
|
| `services/io.py` | Data loading, column normalization (COLUMN_ALIASES), region inference |
|
||||||
|
| `services/forecast.py` | ARIMA grid search, KNN counterfactual, GLM/SVR extrapolation |
|
||||||
|
| `services/strategy.py` | Strategy effectiveness evaluation (F1/F2 metrics, safety states) |
|
||||||
|
| `services/hotspot.py` | Location extraction, risk scoring, strategy generation |
|
||||||
|
| `services/metrics.py` | Model evaluation metrics (RMSE, MAE) |
|
||||||
|
|
||||||
|
### UI Sections
|
||||||
|
|
||||||
|
Each tab in the app corresponds to a `render_*` function in `ui_sections/`:
|
||||||
|
- `render_overview`: KPI dashboard and time series visualization
|
||||||
|
- `render_forecast`: Multi-model prediction comparison
|
||||||
|
- `render_model_eval`: Model accuracy metrics
|
||||||
|
- `render_strategy_eval`: Single strategy evaluation
|
||||||
|
- `render_hotspot`: Accident hotspot analysis with risk levels
|
||||||
|
|
||||||
|
### Session State Pattern
|
||||||
|
|
||||||
|
The app uses `st.session_state['processed_data']` to persist:
|
||||||
|
- Loaded DataFrames (`combined_city`, `combined_by_region`, `accident_records`)
|
||||||
|
- Filter state (`region_sel`, `date_range`, `strat_filter`)
|
||||||
|
- Derived metadata (`all_regions`, `all_strategy_types`, `min_date`, `max_date`)
|
||||||
|
|
||||||
|
### AI Integration
|
||||||
|
|
||||||
|
Uses DeepSeek API (OpenAI-compatible) for generating analysis reports. Configuration in sidebar:
|
||||||
|
- Base URL: `https://api.deepseek.com`
|
||||||
|
- Model: `deepseek-chat`
|
||||||
|
- Streaming response rendered incrementally
|
||||||
|
|
||||||
|
## Coding Conventions
|
||||||
|
|
||||||
|
- Python 3.8+ with type hints (`from __future__ import annotations`)
|
||||||
|
- Functions/variables: `snake_case`; Classes: `PascalCase`; Constants: `UPPER_SNAKE_CASE`
|
||||||
|
- Use `@st.cache_data` for expensive computations
|
||||||
|
- Column aliases defined in `COLUMN_ALIASES` dict for flexible Excel input
|
||||||
|
- Prefer pandas vectorization over loops
|
||||||
|
|
||||||
|
## Data Format Requirements
|
||||||
|
|
||||||
|
**Accident Data Excel** must contain (or aliases of):
|
||||||
|
- `事故时间` (accident time)
|
||||||
|
- `所在街道` (street/region)
|
||||||
|
- `事故类型` (accident type: 财损/伤人/亡人)
|
||||||
|
|
||||||
|
**Strategy Data Excel** must contain:
|
||||||
|
- `发布时间` (publish date)
|
||||||
|
- `交通策略类型` (strategy type)
|
||||||
|
|
||||||
|
## Configuration (config/settings.py)
|
||||||
|
|
||||||
|
Key parameters:
|
||||||
|
- `ARIMA_P/D/Q`: Grid search ranges for ARIMA
|
||||||
|
- `MIN_PRE_DAYS` / `MAX_PRE_DAYS`: Historical data requirements
|
||||||
|
- `ANOMALY_CONTAMINATION`: Isolation Forest contamination rate

### 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
|
```bash
|
||||||
# 构建镜像
|
# 构建镜像
|
||||||
docker build -t trafficsafeanalyzer .
|
docker build -t trafficsafeanalyzer .
|
||||||
|
|
||||||
# 以临时容器方式启动
|
# 运行容器
|
||||||
docker run --rm -p 8501:8501 trafficsafeanalyzer
|
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:
|
访问 `http://localhost:8501` 即可使用。
|
||||||
|
|
||||||
|
如需挂载本地数据目录:
|
||||||
|
|
||||||
```bash
|
```bash
|
||||||
docker run --rm -p 8501:8501 \
|
docker run --rm -p 8501:8501 \
|
||||||
-v "$(pwd)/sample:/app/sample" \
|
-v "$(pwd)/data:/app/data" \
|
||||||
trafficsafeanalyzer
|
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`)。
|
自定义端口:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker run --rm -p 8080:8501 \
|
||||||
|
-e STREAMLIT_SERVER_PORT=8501 \
|
||||||
|

## 升级指南
|
||||||
|
|
||||||
运行 Streamlit 应用:
|
|
||||||
```bash
|
```bash
|
||||||
|
# 备份现有数据
|
||||||
|
cp -r data data_backup
|
||||||
|
|
||||||
|
# 拉取最新代码
|
||||||
|
git pull origin main
|
||||||
|
|
||||||
|
# 更新依赖
|
||||||
|
pip install -r requirements.txt --upgrade
|
||||||
|
|
||||||
|
# 重启应用
|
||||||
streamlit run app.py
|
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**:预测模型页面点击后图表未显示
|
|
||||||
**解决**:确认干预日期之前至少有 10 条历史记录,或缩短预测天数重新提交
|
|
||||||
|
|
||||||
**问题**:热点分析提示“请上传事故数据”
|
|
||||||
**解决**:侧边栏上传事故数据后点击“应用数据与筛选”,热点模块会复用相同数据集
|
|
||||||
|
|
||||||
## 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
|
|
||||||
|
|
||||||
