A multithreaded traffic simulation that demonstrates concurrent programming principles using C++. Vehicles navigate through intersections controlled by traffic lights, with thread-safe communication implemented using mutexes, locks, and message queues.
- Real-time traffic simulation with multiple vehicles
- Thread-safe traffic light system with random cycle durations (4-6 seconds)
- Concurrent vehicle movement and intersection management
- Visual representation using OpenCV
- Message queue-based communication between components
- 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
- Clone this repo.
- Make a build directory in the top level directory:
mkdir build && cd build - Compile:
cmake .. && make - Run it:
./traffic_simulation
The simulation consists of several key components:
- TrafficLight: Manages traffic light phases (red/green) with random cycle durations
- MessageQueue: Thread-safe communication between traffic lights and vehicles
- Intersection: Coordinates vehicle entry and traffic light control
- Vehicle: Simulates vehicle movement and intersection navigation
- Graphics: Renders the simulation using OpenCV
