Intersection-Navigation-and-Path-Estimation

  • Version 1.0
  • September 2020

Introduction

This tool is an extension of to the autonomous driving toolbox for: directed graph creation, path estimation, and vehicle to vehicle communication. The tool provides a method for researchers to perform analysis on intersection related problems. These essential capabilities can help researchers create scenarios, develop path planning algorithms and view them through Mathworks’s Bird Eye Camera. A strong simulation platform helps to provide developers with the tools necessary to develop complex algorithms. Autonomous navigation through intersections is included as a case study since current methods of lane marker following is not a feasible methods of navigation.

Using the Tool

To begin using the tool, please perform the following steps:

  1. Add the project to your Matlab path by right clicking the folder “IntersectionSimulation” and selecting add folder and sub folders to path
  2. run init.m
  3. Open SimulationModel.slx and run the simulation

Scenario Modification

Simulation Parameter Modification

Parameters of the simulation are held in /IntersectionSimulation/Init/ One can change the simulation parameters by modifying one of these files and changing the reference in init.m

Map Modification

To use your own map rather then the one supplied, please:

  1. Open SimulationModel.slx
  2. Modify “SimulationModel/Plant/Scenario Reader” to use your road network
  3. G = Map(‘Your Road Network’, 10e-4)
  4. Save the object to a .mat file
  5. Open “VehicleLogicSimulator.m” and replace 'MarcCityGraphObj.mat' with your new file

Testcases

Testcases for the project can be found in /IntersectionSimulation/Testcases
