According to the information shared by you, a possible way to find the distance travelled by the car can be done using the velocity of the egoCar and leveraging the sample time to find the distance travelled at each time interval and take it's cumulative sum to get the total distance travelled.
Below is the change you can make to your code
function [scenario, egoCar] = createDrivingScenario()
scenario = drivingScenario('StopTime', 10);
roadCenters = [7.1 14.5 0;
31.2 3.1 0;
42.2 -19.5 0];
bankAngle = 1;
laneSpecification = lanespec(2, 'Width', 3.925);
road(scenario, roadCenters, bankAngle, 'Lanes', laneSpecification);
egoCar = vehicle(scenario, ...
'ClassID', 1, ...
'Position', [11.7 15 0]);
waypoints = [11.7 15 0;
20.3 12 0;
25.5 9.2 0;
29.5 6.2 0;
33.6 2.3 0;
37.7 -3.1 0;
40.2 -7.7 0;
42.6 -13.7 0];
speed = [28;32;35;27;38;32;30;30];
trajectory(egoCar, waypoints, speed);
rec = record(scenario);
simulationTime = [rec.SimulationTime];
distanceTraveled = zeros(size(simulationTime));
for i = 2:length(simulationTime)
dt = simulationTime(i) - simulationTime(i-1);
velocityMagnitude = norm(egoCar.Velocity);
distanceTraveled(i) = distanceTraveled(i-1) + velocityMagnitude * dt;
end
disp(distanceTraveled);
rec(end).SimulationTime(1)
The distanceTravelled array will have the distance travelled by the vehicle at each sample time.
Hope this solves your query.
