Concurrent Traffic Simulation

This is the project for the fourth course in the Udacity C++ Nanodegree Program: Concurrency.

This project is a traffic simulation in which vehicles are moving along streets and are crossing intersections. Each intersection is equipped with a traffic light to simulate real world traffic, so that a maximum of one car can be inside an intersection at a given time. A suitable and thread-safe communication protocol manages transmissions between vehicles and intersections. Concurrent programming principles (such as mutexes, locks and message queues) along with Modern C++ features are used to implement the traffic lights and integrate them properly in the code base.

Code Structure

Dependencies for Running Locally

• cmake >= 2.8
  • All OSes: click here for installation instructions
• make >= 4.1 (Linux, Mac), 3.81 (Windows)
  • Linux: make is installed by default on most Linux distros
  • Mac: install Xcode command line tools to get make
  • Windows: Click here for installation instructions
• OpenCV >= 4.1
  • The OpenCV 4.1.0 source code can be found here
• gcc/g++ >= 5.4
  • Linux: gcc / g++ is installed by default on most Linux distros
  • Mac: same deal as make - install Xcode command line tools
  • Windows: recommend using MinGW

Basic Build Instructions

1. Clone this repo.
2. Make a build directory in the top level directory: mkdir build && cd build
