AI Patrol Point Spline with change speed and animation

Hello! I tried to plot a route for the characters. They move from one point to another along the shortest route. How can I make the characters move along curved lines and on certain sections of the line, the characters, according to my purpose, change the animation and speed, for example, from walking to running and vice versa? Is it the same for the camera, so that it moves along curved lines behind the characters and captures them from different angles?

I want to try to create a cartoon, that’s what I need it for. Can someone help? Video lessons on YouTube did not give the desired result.

I am trying to find the same solution to make my mesh switch animations along the spline at specific points or using timeline cues. No hint yet
