State-of-the-art Analysis

My base when starting to research for the current help material/advice/apps/ if you travel with a stroller is to look at how the various commuting systems differ in different cities. I looked into Helsinki, Gothenburg(Västtrafik), Malmö(Skånetrafik), Paris, Toronto & New York. Very different cities but it's cities where the majority commute. 

In Helsinki, the attitude is very welcoming towards travelers with a stroller. They offer free ride for every owner of a stroller(as in Stockholm) and their website describes information about where there is room & space along with safety information on how to get around.
Similar to Stockholm buses, they have a button especially for the travelers with strollers to push so the doors will keep open for a longer time than normal.

However, when reading about the information given on Västtrafiks website, the attitude is completely different. The information seems to give an impression for the travelers with strollers to be the least prioritized. The information given is that "you travel upon availability (...) make sure to park the stroller so it isn't in the way for others."

Skånetrafik is a combination of Helsinki's and Västtrafik's commuting system. You travel upon availability and you travel with free of charge. But only if there's a baby in the stroller, otherwise it's demanded to buy a "ticket for the stroller", a corresponding ticket for bicycles.

Finally, when it comes to Paris, Toronto & New York, they function quite the same for the travelers. It is adapted to people with dysfunctions. It is marked on the maps and the stations whether it's a station adapted to those with disabilities or not and they point out on how their commuting system is trying to get more adapt. 
But there is no information for if you travel with a stroller and considering on how the trams, subways and buses are built, the vehicles for traveling are not very stroller-friendly. The aim and purpose seems to be to fit as many people as possible. 

Similar to how the information is given to people with disabilities, the commuting systems could be much more clear on giving information for travelers with strollers and how to best make the trip suitable for the traveler.
