Both photographs were taken using slow shutter speeds (about 0.25 seconds) with flash. This technique gives a great sense of movement.
Panning during the exposure gives the streaks and the short flash duration of the flash stops the action. When using this technique, it’s important to pan in the opposite direction of the moving object, otherwise the “streaks” will appear to be going forward (in front of the subject’s direction of movement), rather than backwards, which will make the subject look like it’s reversing.

The Bus photo was also take with a gradated red filter. Back in the early 80’s Cokin gradated filters were the “new thing” in photography. One doesn’t see gradated filters being used so much now-a-days, except in TV commercials, where they are used to colour in dull overcast skies. You can usually tell when they are being used because the bottom half of the photo doesn’t have the same colour in its reflections as the predominant colour of the sky as would happen naturally.
