Moving camera along the road in 3d model

Hello,

I have a 3d model of a park

I want to move the camera along the road. I can split only the road from the 3d model using scene.children array but I have no idea about how to move the camera along this road please check link below you can get idea from it

Have a nice day !

            			const position = new THREE.Vector3();
            			const tangent = new THREE.Vector3();
            
            
			const lookAt = new THREE.Vector3();
            
            
			let velocity = 0;
            			let progress = 0;
            
            
			let prevTime = performance.now();
            
            
			function render() {
            
            
				const time = performance.now();
            				const delta = time - prevTime;
            
            
				for ( let i = 0; i < funfairs.length; i ++ ) {
            
            
					funfairs[ i ].rotation.y = time * 0.0004;
            
            
				}

Looking at the render code for this example, the camera is moved along a series of positions extracted from the points along the track. Perhaps you could adapt this for your needs.
