<!-- ABOUT THE PROJECT -->
# About The Project
<!-- <div align="center">
  <img src="images/example.jpg" alt="map" width="400"/>
</div> -->

Transit agencies use the General Transit Feed Specification (GTFS) to publish transit data. More and more cities across the globe are adopting this GTFS format to represent their transit network. The GTFS feed can be downloaded from [@transitfeeds](https://transitfeeds.com/) and [@mobility data](https://mobilitydata.org/). The GTFS segments is a concise representation of GTFS files removing unnecessary repetitions in the data. We do that by considering the services offered only the busiest day(in the data) and representing data in the form of segements.

<!-- GETTING STARTED -->
# Getting Started

## Prerequisites
The major dependencies of this library are the following packages. 
* numpy
* shapely
* pandas
* geopandas
* partridge
* matplotlib
* contextily

The detailed list of package dependencies can be found in `requirements.txt`

## Installation

### Option A

Use pip to install the package. Windows users may have to download and install Microsoft Visual C++ distributions. Follow [these](https://stackoverflow.com/questions/29846087/error-microsoft-visual-c-14-0-is-required-unable-to-find-vcvarsall-bat) instructions. 

```sh
pip install gtfs-segments
```
### Option B

1. Clone the repo
    ```sh
    git clone https://github.com/UTEL-UIUC/gtfs_segments.git
    ```
2. Install geopandas using the following code. Read more [here](https://geopandas.org/en/stable/getting_started/install.html)
    ```sh
    conda create -n geo_env
    conda activate geo_env
    conda config --env --add channels conda-forge
    conda config --env --set channel_priority strict
    conda install python=3 geopandas
    ```
3. [Optional] Download modified version of `partridge` library and install it manually.
    ```sh
    git clone https://github.com/praneethd7/partridge
    cd partridge
    python setup.py install
    ```
4. Install requirements using
    ```sh
    pip install -r requirements.txt
    ```     
5. Install the `gtfs_segments` package
    ```sh
    cd gtfs_segments
    python setup.py install
    ```

<!-- USAGE EXAMPLES -->
# Usage

For documentation, please refer to the [Documentation](https://utel-uiuc.github.io/gtfs_segments_docs/)

Import the package using 
```python
import gtfs_segments
```
## Get GTFS Files

### Fetch all sources
```python
from gtfs_segments import fetch_gtfs_source
sources_df = fetch_gtfs_source()
sources_df.head()
```

<div align='center'><a>
    <img src="images/sources.jpg" alt="sources" width=800>
</a></div>  

### Fetch source by name/provider/state
```python
from gtfs_segments import fetch_gtfs_source
sources_df = fetch_gtfs_source(place ='Chicago')
sources_df
```
<div align='center'><a>
    <img src="images/sources_chicago.jpg" alt="sources" width=800>
</a></div>   

## Automated Download  
```python
from gtfs_segments import download_latest_data
download_latest_data(sources_df,"output_folder")
```
## Manual Download
Download the GTFS `.zip` files from [@transitfeeds](https://transitfeeds.com/) or [@mobility data](https://mobilitydata.org/).


## Get GTFS Segments
```python
from gtfs_segments import get_gtfs_segments
segments_df = get_gtfs_segments("path_to_gtfs_zip_file")
segments_df
```
<div align='center'><a>
    <img src="images/data.jpg" alt="data" width=800>
</a></div>  

## Visualize Spacings

```python
from gtfs_segments import view_spacings
view_spacings(segments_df,route = '18131',segment = '6294-6290-1',basemap=True)
```
<div align='center'><a>
    <img src="images/visualize.jpg" alt="data" width=600>
</a></div>  

## Plot Distributions
```python
from gtfs_segments import plot_hist
plot_hist(segments_df, max_spacing = 1200)
```
<div align='center'><a>
    <img src="images/hist.jpg" alt="histogram" width=800>
</a></div>  

Optionally save figure using
```python
plot_hist(segments_df,file_path = "spacings_hist.png",save_fig = True)
```

## Get Summary Stats
```python
from gtfs_segments import summary_stats
summary_stats(segments_df,max_spacing = 3000,export = True,file_path = "summary.csv")
```

<div align='center'><a>
    <img src="images/summary.jpg" alt="histogram" width=400>
</a></div>  


## Download Data
Download the data as either `.csv` or `.geojson`
```python
from gtfs_segments import export_segments
export_segments(segments_df,'filename', output_format ='geojson')
# Get csv without geometry
export_segments(segments_df,'filename', output_format ='csv',geometry = False)
```
