Traffic Lights

Overview

Shows a set of traffic lights at an intersection. Designed to work with multiple types of intersections, but the example is based on a 4-way cross-intersection.

Install

Clone repository and install dependancies. Requires Node (tested with Node 6.x)

$ git clone git@github.com:rogchap/traffic-lights.git
$ cd traffic-lights
$ npm i

Run

$ node traffic-lights

To see all available options run the help

$ node traffic-lights -h

The program is designed to run in two formats:

1. start will output a visual of a cross-intersection.
2. simulate will "dump" an output of states over a given time

start (default):

simulate:

You can change the interval time and the time on amber with flags -i and -a; for example to have an interval of 5 minutes with 30 seconds at amber:

$ node traffic-lights -i 300 -a 30

To simulate an output over 30 minutes, use the time (-t) flag with simulate:

$ node traffic-lights simulate -i 300 -a 30 -t 1800

Tests

$ npm test
