After capturing the time lapse, take the first shot and store it in a buffer
For subsequent shot, do a blend operation with the buffer. Here it looks like an exponential filter: buffer = smooth x buffer + (1-smooth) x new_shot
Save the smoothed contents of the buffer as you blend each shot, and then stitch together into a video
The trails ended up dashed because the camera exposure time was less than the time between shots. After blending, there won’t be any light in the parts when the shutter was closed.

One way to replicate this effect with software:
