Functions to create two sample scenarios are included in the repository, one for a T-Junction ( createTJunctionScenario.m) and one for a four-way junction ( createFourWayJunctionScenario.m). The drivingScenario object containing the road network can be created using the DrivingScenarioDesigner or its programatic API. To set up a simulation users must create a road network and specify the driving direction and connectivity of lanes and turns. The repository includes one such controller, in a TrafficLight class that inherits from TrafficController To implement user defined traffic control logic, TrafficController can be used as a parent class and the relevant methods can be overriden.A vehicle should react to an upcoming closed Node by not entering it. It controls them by setting the Node as open or closed. A TrafficController object is associated with all Nodes (i.e.A TrafficController class that is used to model and implement traffic rules and signalization.To implement user defined driving logic, DrivingStrategy can be used as a parent class and the relevant methods can be overriden.These models guarantee safe front to back driving, but rely on proper junction controllers to avoid lateral collisions.

Two car following models, the Gipps Car Following Model and the Intelligent Driver Model, are pre-programmed into the DrivingStrategy class and they can be used to benchmark againts a human driven scenario.The DrivingStrategy object implements car following longitudinal control, and tracks the center lane statically, that is, it assumes no dynamics for lane keeping.A DrivingStrategy class that controls the vehicles in the network.To connect vehicles and traffic controllers.To provide a mapping between global position, the station distance along the length of the lane, and the direction and curvature of the lane.To represent the network as a directed graph of connected lanes and turns that vehicles can use to specify their routes through the network.
A Node class that is used for three main purposes:.Crucially, three classes that need to be understood are added:
#INTEGRATED MODELLING TOOLBOX MATLAB PYTHON SIMULATOR#
The structure of the simulator makes use existing classes of the Driving Scenario Designer App, like drivingScenario, Vehicle, and Actor. Concepts of OOP, and OOP in MATLAB can be reviewed here. OpenTrafficLab is built using an Object Oriented Programming (OOP) architecture. To get started, users can go through OpenTrafficLabIntroductoryExample.mlx for a documented example covering scenario creation, junction controller creation, vehicle generation, and running a simulation using the provided car following models.
To run this model, you need: MATLAB, Automated Driving Toolbox TM. The version tested with MATLAB R2020a is being developed. This model has been tested with MATLAB R2020b. Refer to the documentation here for more information. OpenTrafficLab is meant to extend this functionality by simulating traffic in closed loop simulation, where the vehicles' speed trajectories are not given apriori but are the product of a state dependent control logic.ĭriving Scenario Designer Application is part of Automated Driving Toolbox. However, the motion of the vehicles is meant to be specified before the simulation is ran by specifying waypoints to the vehicles' trajectories manually. These tools can be used efficiently to represent road networks, populate them with vehicles and specify their trajectories. The simulator makes use of tools in the Automoted Driving Toolbox TM, namely, the DrivingScenarioDesigner app and the drivingScenario object it generates. The purpose of the simulator is test multi-agent autonomous vehicle control algorithms and intelligent traffic control algorithms.

The simulator provides models for human drivers and traffic lights, but is designed so that users can specify their own control logic both for vehicles and traffic signals. OpenTrafficLab is a MATLAB® environment capable of simulating simple traffic scenarios with vehicles and junction controllers.
