Is there a way to get attibutes of a road?

[ROADRUNNER] For example, coordinates of the road, length of the road, number of objects on the road, number of lanes, etc?

In MATLAB, you can use the RoadRunner application to create and edit scenarios for simulating and visualizing driving environments. To get attributes of a road such as coordinates, length, number of objects, and number of lanes, you can use various functions provided by MATLAB’s Driving Scenario Designer app or Automated Driving Toolbox123.

Here’s a general approach to obtain these attributes:

1. Create a Driving Scenario: Use the drivingScenario function to create a scenario object.
2. Add Roads: Use the road function to add roads to your scenario. You can specify the shape and orientation of the road segment in the 2-D plane using a set of road centers3.
3. Get Road Boundaries: Use the roadBoundaries function to get the road boundaries of a driving scenario. This function returns the road boundaries that the actor follows in a driving scenario2.
4. Get Road Attributes: You can obtain the length of the road and the number of lanes by analyzing the road boundaries and the road object properties.
5. Add Objects: Use the actor or vehicle function to add objects to the road and specify their attributes.
6. Analyze Scenario: Use the actorPoses function to get the poses of all actors (including objects) in the scenario.

%For example, to get the road boundaries, you can use the following code snippet:
scenario = drivingScenario('SampleTime',0.1, 'StopTime',60);
% Define road center points and add a road
roadcenters = [700 0 0; 100 0 0];
road(scenario, roadcenters);
% Get the road boundaries
rbdry = roadBoundaries(scenario);

The rbdry variable will contain the road boundaries, where each cell in the cell array contains a real-valued N-by-3 matrix representing a road boundary in the scenario2.

Please note that the specific functions and methods to use will depend on your version of MATLAB and the available toolboxes. Always refer to the official MATLAB documentation for the most accurate and up-to-date information. Let me know if you need further assistance!
