Public transport-ship — Passenger ship about to dock

Public transport allows traveling for citizens, decreasing the number of private vehicles on the road and alleviating traffic and traffic-created noise pollution. Transportation come in various methods: bus stations, metro stations, train stations, airports, harbors, and taxi stands.

^[1]

Transportation can be used for various purposes:

Intra-city transport (commuter, tourist, cargo)
Inter-city transport (tourist, cargo)

The Space Elevator is a monument to attract tourists. It is labelled as 'Public Transport'.

Types of transportation[]

Airports[]

Airports are a mode of public transport that can take tourists to your city. Although creating heavy noise pollution, they will help your city to gain more tourists.

Blimp[]

Only with Mass Transit DLC

Each blimp has a capacity of 35 passengers, just 5 more than buses. You need to mark Pathways for the blimps to travel. Blimps fly from stop to stop and need a route to the Blimp Depot. Pathways are two-way, basically like virtual roads for Blimps. Stops need a road connection, but other than that, can freely be placed anywhere on the map. Depots need to be connected to roads as well, but can send vehicles to any line they have a Pathway connection with.

As an extra benefit, there is space on the sides of Blimps for advertisements. By default they show adverts from various companies, but if you wish to use the space to your city’s benefit, you can set a policy so that Blimps show educational posters. This boosts your city’s education facilities a little bit.

Bus[]

Bus services allow citizens to travel in a public vehicle through designated stops. Bus depots can sustain an unlimited amount of buses, in the expense of a hefty price for purchasing bus depots. Bus lines are travel routes with designated stops, created by placing bus stops around a city and looping it back to the starting position.

Bus lanes (roads)[]

Bus lanes road are found in the road section or the bus section in transportation. Having these roads are good to have since buses and even taxis can go on these lanes unless if they are about to turn right. The only disadvantage is that other vehicles are forced to move to the other lanes which may turn that into heavy traffic.

Trolleybus[]

Only With Sunset Harbor DLC

Trolleybuses are electric buses hooked up to electrical wires above roads. They are similar to trams but do not function as a "train" and can cross metro tracks. They cannot cross train or tram tracks due to them already having wires above them. Unlike buses, they cannot go wherever.

Roads[]

Special roads are needed for trolleybuses to travel on. Trolleybuses cannot u-turn, so the roads must be a loop. There is no six lane road with trolleybus wires.

Cable Cars[]

Only With Mass Transit DLC

The Cable Cars are very useful on steep slopes, but can also be placed on level ground. They can be used to cross rivers or other bodies of water if you want. There are two types of stops: end-of-line stops and stops where Cable Cars can pass through and continue to further stops. Pass through stops can also be used at the ends. Cable Cars lines are somewhat easier to set up than other types. Build the stops you want to have in the city and connect them with cables. When any two or more stops are connected, the line will start to operate automatically. All stops connected to each other are considered one line. Cables can go over roads and their height can be adjusted with PgUp and PgDown, just like roads. However the cables cannot pass over houses or buildings. Cables can be built on water, even so that the concrete bases of the pylons are standing in the water.

Cable Cars don’t have a huge capacity, but they run often, allowing a constant stream of passengers to be transported. It's best for steep slope travelling, since cars and roads can't go on steep places.

Tram (Only with Snowfall DLC)[]

Tram services are available in Cities: Skylines Snowfall. Trams operate on tracks and are stationed in tram depots when inactive. Tram tracks can be built on existing roads with versions of the tracks. Tracks can also be standalone with no road beneath them. Trams are capable of transporting 90 passengers with vanilla trams. However, unlike buses, trams have nearly 15% higher upkeep costs per distance traveled. Trams are not hindered by snow.^[2] They are more costly to maintain than buses.

Tram tracks[]

There are different varieties of them some by themselves or either along a road. The most disadvantage about this is that they don't have a six-lane road version for it compared to the six-lane road with bus lane (see buses)

Metro[]

Metro services are underground transportation, suitable for heavily populated and largely condensed cities. Metros can be added by placing a metro station. Metros travel through tunnels, which can be created through the tunnel tool and work similarly to the road system. Like buses, metros require loops to be created in order for citizens to travel.

An International Airport has one inside it.

As of the Sunset Harbor free patch, metro lines can now be placed above ground, and even be elevated above the ground. Two new types of metro station were made to accommodate these new ways of placing lines. The size of the existing underground metro stations were also changed, making them longer. The original metro stations still work as normal in old cities.

Train[]

Trains use the railway system that allows both passenger travel and cargo travel through land. Train tracks can be placed throughout the city to allow traveling.

Harbor[]

Harbors are water-based transport that may carry passengers and cargo coming from outside sources. Ships do not need routes, but they do require a path to and from harbors and outside connection. Some maps do not have ship routes, therefore these buildings cannot be built in those maps.

Monorail[]

Only With Mass Transit DLC

Each monorail has a capacity of 180 passengers, 2x more than trams and 6x more than buses. For the monorail, you need to build stations. Monorails can be built on top of roads. A new avenue type has been added with monorail tracks going on top of the section between lanes. This avenue is just like a regular road, so that you can easily upgrade existing roads to use it. While the monorail has stand-alone stations that work just like stations for any other transport type, you can also place it on top of a road. The tracks also work without a road, so you can connect sections of stand-alone track and sections of track on top of an avenue. Like with the updated train tracks, both one- and two-way monorail tracks are available. However, they cannot be build over 6 lane roads due to a road with them not existing.

Taxi (Only with After Dark DLC)[]

Taxi services are available in Cities: Skylines After Dark. Taxi mainly serves as tourist transportation and are highly recommendable for commercial districts. Taxis are available through taxi depots. Unlike bus and metro lines, taxis wait for calls from citizens by waiting in taxi stands and begin traveling to the citizen when called for.
