Traffic Simulation and Visualization

I've decided to open-source this source code under GPLv3(GNU General Public License, version 3) after my graduation from the university.

This is an intersection simulation software capable of generating the arriving vehicles in many varying controllable rates. The vehicle behavior can be changed in realtime in the following mode:

whether to respect the traffic lights' existence, treat front vehicles as invisible or not.

Features:

• Cross-platform Qt5 application
• Real-time traffic simulation and visualization
• CMake build system support for easy compilation
• Multiple build methods (CMake, qmake, Qt Creator)

Tested Systems

I have complied the source code and test on the following systems:

• Windows 10 20H2 19042
• macOS Big Sur 11.2.1
• Ubuntu 20.04.2 LTS

Build Instructions

RISV requires Qt 5.0.0+ to compile and run. The source code can be compiled using one of these options.

Clone the source code

$ git  clone  https://github.com/KimangKhenng/Traffic-SImulation-and-Visualization.git  

Build with CMake (Recommended)

This project now supports CMake build system for better cross-platform compatibility.

Prerequisites

• CMake 3.1.0+ - Install using your system's package manager
• Qt 5.0.0+ - Download from Qt Official Website
• GCC/Clang compiler with C++11 support

Ubuntu/Linux

# Install dependencies
sudo apt update
sudo apt install cmake build-essential

# If Qt is not installed system-wide, skip this step
# sudo apt install qtbase5-dev qt5-qmake qttools5-dev libqt5svg5-dev libqt5opengl5-dev

# Clone and build
git clone https://github.com/KimangKhenng/Traffic-SImulation-and-Visualization.git
cd Traffic-SImulation-and-Visualization

# Create build directory
mkdir build && cd build

# Configure with CMake (adjust Qt path as needed)
cmake -DCMAKE_PREFIX_PATH=/path/to/your/Qt5.x.x/gcc_64 ..

# Build the project
make -j$(nproc)

# Run the application
export LD_LIBRARY_PATH=/path/to/your/Qt5.x.x/gcc_64/lib:$LD_LIBRARY_PATH
./IntersectionRoadSimulationandVisualization

Windows

# Ensure CMake and Qt are in PATH
# Open Command Prompt or PowerShell

git clone https://github.com/KimangKhenng/Traffic-SImulation-and-Visualization.git
cd Traffic-SImulation-and-Visualization

mkdir build && cd build
cmake -DCMAKE_PREFIX_PATH="C:\Qt\5.x.x\msvc2019_64" ..
cmake --build . --config Release

# Run the executable
Release\IntersectionRoadSimulationandVisualization.exe

macOS

# Install CMake using Homebrew
brew install cmake

git clone https://github.com/KimangKhenng/Traffic-SImulation-and-Visualization.git
cd Traffic-SImulation-and-Visualization

mkdir build && cd build
cmake -DCMAKE_PREFIX_PATH="/path/to/Qt5.x.x/clang_64" ..
make -j$(sysctl -n hw.ncpu)

# Run the application
export DYLD_LIBRARY_PATH="/path/to/Qt5.x.x/clang_64/lib:$DYLD_LIBRARY_PATH"
./IntersectionRoadSimulationandVisualization

Creating a Launch Script (Linux/macOS)

Create a script to easily run the application:

#!/bin/bash
export LD_LIBRARY_PATH="/path/to/your/Qt5.x.x/gcc_64/lib:$LD_LIBRARY_PATH"
cd /path/to/Traffic-SImulation-and-Visualization/build
./IntersectionRoadSimulationandVisualization

Quick Run on Windows, Mac, and Linux with Qt Creator

• Open the project with Qt Creator.
• Configure project with either MinGW or Visual Compiler
• Run

Manually Build Release on Windows with MingGW

Make sure you add Qt/5.XX/mingw/mingwXXX_64/bin/ and Qt/Tools/mingwXXX_64/bin/ to your PATH in system environment variables.

$ cd Traffic-SImulation-and-Visualization  
$ qmake  
$ mingw32-make  
$ mingw32-make clean  
$ cd release  
$ windeployqt --quick --no-translations .  

Common Issues and Solutions

• Qt5 not found: Make sure to set CMAKE_PREFIX_PATH to your Qt installation directory
• Missing libraries at runtime: Set the appropriate library path environment variable
• Build errors: Ensure you have C++11 compatible compiler and all Qt components are installed
