What is vehicle trajectory?
The trajectory means vehicle location, speed, acceleration and jerk, as time functions. Numerous technologies are available for trajectory measurement, used in roadside and on-board observatories.
What is trajectory forecast?
Trajectory forecasting is a sequential prediction task, where a forecasting model predicts future trajectories of all moving agents (humans, vehicles, etc.) in a scene, based on their past trajectories and/or the scene context.
What is a trajectory in physics?
A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously.
How do you use the word trajectory?
the path followed by an object moving through space.
- The missile deflected from its trajectory.
- My career seemed to be on a downward trajectory.
- The decision was certain to affect the trajectory of French politics for some time to come.
How do you describe trajectory?
A trajectory is the path of an object through space, or the path of life that a person chooses. Trajectory comes from the Latin trajectoria, which means “throw across.” If you wanted to describe the path of a jet through the sky, you could refer to the jet’s trajectory.
What is an example of trajectory?
The definition of a trajectory is the curved path something takes as it moves through space. An example of trajectory is the path taken by a paper airplane as it flies through the air. The curved path of something hurtling through space, esp. that of a projectile from the time it leaves the muzzle of the gun.
How to create trajectory in a driving scenario?
Set a trajectory in which the vehicle drives around the curve at varying speeds. Plot the scenario and run the simulation. Observe how the vehicle slows down as it drives along the curve. Create a driving scenario consisting of two, two-lane roads that intersect at a right angle.
How to calculate the trajectory of a vehicle?
Create a driving scenario and add a curved two-lane road to it. Add a vehicle to the scenario. Set a trajectory in which the vehicle drives around the curve at varying speeds. Plot the scenario and run the simulation. Observe how the vehicle slows down as it drives along the curve.
What do AC waypoints and speed mean in trajectory?
trajectory (ac,waypoints,speed) also specifies the speed with which the actor or vehicle travels along the trajectory, in either forward or reverse motion. trajectory (ac,waypoints,speed,waittime) specifies the wait time for an actor or vehicle in addition to the input arguments in the previous syntax.
How to create a trajectory for an actor?
The trajectory function creates a trajectory for an actor to follow in a scenario. A trajectory consists of the path followed by an object and its speed along the path. You specify the path Run the command by entering it in the MATLAB Command Window.
