First of all, the rating is only related to buildings with tourists, such as hotels, observation decks and lighthouses. For example, if there is a lack of food, a restaurant must be built next to the hotel to improve the level. Other positions are useless. The demand level of each building is calculated separately, but it affects the whole situation. Click on the management map and you can see what the building needs by color.

Knowing this, it's easy to improve your score.

First, hotels are gathered together, so that you only need a few entertainment buildings to meet the needs of hotels. Otherwise, there should be entertainment buildings near every hotel.

Second, when placing viewing platforms and other viewing buildings, we must leave space for entertainment buildings, otherwise the score will be lowered.

Speaking of traffic demand, at present, we haven't found any influence on the scores of roads with different qualities, so it is very simple to improve the traffic scores. Again, as I said at the beginning, as long as you can meet every observation deck, hotel and other places, and there is a train to arrive, your score will rise sharply.

If it still doesn't rise, you can try to build more roads (this is doubtful at present. )

In short, only hotels, observation decks and other buildings where tourists gather, and only nearby entertainment buildings will affect the score.
