Traffic-Simulator

Traffic-Simulator, highly performant large-scale traffic visualization

Before starting

Introduction

This project is a Traffic-Simulator developped in case of studies project.

We developed it with Unity3D in C#.

This simulator is based on New York City traffic, in fact there are pedestrian, differents kind of cars like truck or city-dweller car. There is not roundabout, cars can not cross each other and pedestrian can not cross the street.

For a better introduction you can watch this video which resume our Traffic-Simulator project.

Download the project

You can clone or download the project by clicking on the button "Clone or Download". Or you can get this command on terminal

git clone https://github.com/leirbag95/Traffic-Simulator.git

How to try it ?

• Clone the project and launch it with Unity, then Build & Run the project with the OS you want.

• Download the project for Mac OS through this link

How does it work ?

Once you have started the program, you will be in front of the main menu where you will have several choices:

• Start a local traffic simulator

A traffic simulator will be randomly selected from a local database of document. In fact, you have a dozen of maps which are provided with the project.

• Upload your own city

Maps are generated from a JSON file. We made this simulator in order to upload your own map. Everything are explained in the specification.

Below you have an example of what looks like a city through a JSON file required

{
  "name":"Pulv City",
  "rows":17,
  "cols":10,
  "grid": [
  	["", "", "", "", "", "", "", "", "",""],

Modeling a road

Road are modeling by a matrix of GameObject. There are several types of GameObject :

GameObject representing the road

---

These kind of GameObject represent the direction of the road, in fact each Road GameObject has a peer of Node.

1. TB : TOP to the BOTTOM
2. BT : BOTTOM to the TOP
3. RL : RIGHT to the LEFT
4. LR : LEFT to the RIGHT
5. CNO : CENTER NORTH WEST
6. CNE : CENTER NORTH EAST
7. CSO : CENTER SUD WEST
8. CSE : CENTER SUD EAST
