A package that gets traffic data from LTA datamall APIs.

Project description

# lta-datamall-crawler

[![Build Status](https://travis-ci.org/hiimivantang/ltadatamallcrawler.svg?branch=master)](https://travis-ci.org/hiimivantang/ltadatamallcrawler)

LTA is responsible for planning, operating, and maintaining Singapore's land transport and systems.

This repository contains a python module to get data from LTA's [datamall][1] (free). Maybe I should not name this repository as LTA-datamall-crawler but you can always create a simple cronjob for crawling purposes.



### Installation

```python

pip install ltadatamallcrawler

```

Or, you can always clone this project and run the script directly.



### Requirements

You will need LTA datamall API key and GUUID.
To get the API key, click "Request for API Access" on the [LTA datamall page][3]. API key will be granted immediately. Using the API key, you can generate a GUUID on [this page][4].


### Usage

```bash
# to view the available APIs:

lta-datamall-crawler -h




# Expected output:

Usage: lta-datamall-crawler [options]

#Options:
# -h, --help show this help message and exit
#
# Available APIs:
# Please select one!
#
# --traffic-incidents
# --bus-arrival
# --bus-routes
# --estimated-travel-times
# --road-openings
# --erp-rates
# --vms-emas
# --taxi-availability
# --faulty-traffic-lights
# --carpark-availability
# --bus-stops
# --traffic-images
# --traffic-speed-bands
# --bus-services
# --road-works




# to get 'real-time' traffic incidents data

lta-datamall-crawler --traffic-incidents


```




### Motivation

Sometimes it can be quite labourous to create boilerplate codes for doing HTTP get requests to different APIs even though the [requests package][2] can make life slightly easier. I've created this project to make life easier for people who are interested in getting traffic data from Singapore LTA datamall.
