>>1258604Really depends on the size of the city. But in any case, the idea would be to offer many good alternatives to car travel, so that you would be discouraged from using a car on most trips.
In any case, I would want a city center either pedestrianized except for a few streets, or with cars allowed at walking speed everywhere. There would be a traffic hub adjacent to the city center, with two or more main public transport arteries intersecting.
>Below 50k inhabitants: One to three tram lines, busses, biking and walking possible everywhere >50k to 100k: Extensive tram and bus network, more than one railway station with frequent service. You can't walk everywhere, but biking must still be feasible. >100k to 300 000k: Extensive tram/light rail network. Maybe a single metro line. Busses only for regional and neighborhood service. >300k to 500k: Combined metro/tram network. Maybe one or two tangential tram lines. 10 or more railway stations in the city. Busses for neighborhoods and the countryside. >500k to 1m: Most traffic handled by metro. City has to have a commuter rail network centered on it now. Trams supplement and feed heavy rail. Busses mostly irrelevant. >1m+: Metro everywhere, metro ring lines around city center. Commuter rail serving both city and countryside. Maybe commuter ring line. Trams in feeder and interurban mode.
