WebPlan and Visualize Trajectory. Create a reference path for the planner to follow. refPath = [0,25;100,25]; Initialize the planner object with the reference path, and the state validator. planner = trajectoryOptimalFrenet (refPath,stateValidator); Assign longitudinal terminal state, lateral deviation, and maximum acceleration values. WebThere are multiple ways to select the longitudinal trajectory in the frenet frame. This part involves the interaction of vehicle surrounding (the sensor fusion part). Since we in a three lane traffic, the vehicle movement will be much natural and smooth if it adapts the ongoing traffic flow. Which will result in behavior like: no vehicle ahead ...
