Concurrent traffic simulation in C++.

Primary LanguageC++

Project 4 - Concurrent Traffic Simulation

This is the fourth project from Udacity's C++ Nanodegree Program. It covers concurrency, especially threads, tasks, futures, mutexes, locks and message queues in the coding language C++.

Project Overview

Goals:

  • Implement the logic for traffic lights.
  • Add a message queue to prevent data races, deadlocks and improve performance and responsibility of the program

Structure:

The project is divided into different files. All header files can be found in the include folder.

  • src/graphics.cpp (and header file): Logic for visualization of the traffic simulation
  • src/intersection.cpp (and header file): Class for the intersection objects with the corresponding functions and logic
  • src/street.cpp (and header file): Class for the streets connecting intersections
  • src/TrafficLight.cpp (and header file): Class for the traffic light objects with the corresponding functions and logic
  • src/TrafficObject.cpp (and header file): Parent class for TrafficLight, street, intersection and Vehicle
  • src/TrafficSimulator_Final.cpp: Main logic of the traffic simulation
  • src/Vehicle.cpp (and header file): Class for the vehicle objects with the corresponding functions and logic
  • other helper, build and installation files

Dependencies

  • cmake >= 2.8
  • make >= 4.1 (Linux, Mac), 3.81 (Windows)
