Connection Scan Algorithm in PHP
================================

[](#connection-scan-algorithm-in-php)

Simple library to compute public transport routes directly based on timetable data.

Overview
--------

[](#overview)

This library provides a basic implementation of the CSA (Connection Scan Algorithm) introduced 2013. To use this algorithm with data from public transport agencies, there's no need to build a graph out of them like this would be using the Dijkstra or the A\* algorithm.

Sadly there're only a few little projects using this algorithm in practice. The intent to develop this library is not to re-invent the wheel but learn about the issues when using 'real data' and how to fix them as well as keeping a simple and extendable PHP implementation of CSA which can be used in other projects.

Installation
------------

[](#installation)

To use this library, add it to your composer dependencies by typing

```
composer require gtfs/csa-routing

```

or when beginning from the scratch, simply clone this repo and type

```
composer install

```

in your command line environment.

Usage
-----

[](#usage)

For usage there're two main classes called `Scanner` (for computing the connections) and `Journey` for back-routing and computing your route.
