This is a must have DLC from a public transportation perspective. Cims are willing to bike across the city on dedicated cycle paths, which helps free up congestion on the roads. Bus terminals are also pretty nice, though taxis are pretty useless imo. The rest of the improvements are nice and add depth to base game systems.

The snow maps are cool, but imo the real reason to buy this DLC is for the trams. I wouldn't suggest paying full price, but at over half off it's a pretty good deal if you regularly make use of public transport. The 90 passenger capacity of trams is really nice compared to the 30 on a bus or trollybus, so really useful in busy cities or to transport tourists from an airport or cruise ship.
