oooo, night shots...
*cracks knuckles*
Ok, good start and good ideas. Night shots are fraught with technical challenges, so let me give you some tips.
First, white balance... night shots will tend to have horrible white balance issues caused by a variety of types and sources of light. #1 rule, always shoot in RAW for night shots and then correct for proper white balance later. All of these appear to be off... too orange, I think. Not 100% sure, but definitely not quite right.
Second, tripod and remote shutter release. These do look blurry, but as I look at them, I think it may be a focus problem. Just make sure you are using a tripod and a remote shutter release. In dire cases you can do the timed shutter, but it's a royal pain and doesn't work as well because you have to hit the camera and then give it long enough to stop shaking from your click... really slows you down and doesn't always work.
Third, manual focus... do not autofocus with night shots. I suspect this is the reason why your images are blurry, and I see you
did use AF. You want to manually focus your camera to infinity... use hyperfocal focusing if possible, but at least focus to infinity. Note that some lenseswill not have infinity labeled, or it will be labeled improperly. You will need to experiment with yours to see, and you will want to do this BEFORE your shoot so you know where you need to be. Mark your lens if necessary.
Fourth, exposure time... it can be your enemy, it can be your friend. Mostly it can be your enemy.

Night shots tend to be crazy with various lights, so you want to obviously set the exposure long enough to get your shot, but not so long as to be polluted. IMO the shot you have of the road is polluted... far too many cars passed by and it just mottles the scene.
Fifth, remember that night shots are all about light. Ironic, but true.

If there isn't a lot of interesting light in your shot, the shot will be somewhat uninteresting.
EDIT: You also may want to play a bit with PP on these... sometimes you need to darken, or increase contrast, or or or... play around with that a bit. It might bring back some detail on the road shot.
Try that for a start.
BTW, if you're interested, let me know and I'll post some example night shots I've taken.
