A Python implementation of core OSRM (Open Source Routing Machine) functionality.

## Installation

```bash
pip install py-osrm-backend
```

## Features

- **OSM Parsing**: Parse `.osm` XML files to extract nodes and ways
- **Graph Building**: Build a routable graph with haversine distance weights
- **Routing**: Dijkstra's algorithm for shortest path computation
- **API Server**: Flask-based REST API compatible with OSRM-like endpoints

## Quick Start

```python
from osrm.extractor.graph_builder import GraphBuilder
from osrm.engine.dijkstra import DijkstraEngine

# Build graph from OSM
builder = GraphBuilder()
graph = builder.build_graph("your_map.osm")

# Route
engine = DijkstraEngine(graph)
distance, path = engine.shortest_path(start_id, end_id)
print(f"Distance: {distance} km, Path: {path}")
```

## Run Tests

```bash
python -m unittest discover -s tests -v
```
