Intermodal passenger transport

Intermodal passenger transport, also called mixed-mode commuting, involves using two or more modes of transportation in a journey. Mixed-mode commuting is often used to combine the strengths (and offset the weaknesses) of various transportation options. A major goal of modern intermodal passenger transport is to reduce dependence on the automobile as the major mode of ground transportation and increase use of public transport. To assist the traveller, various intermodal journey planners such as Rome2rio and Google Transit have been devised to help travellers plan and schedule their journey.

Mixed-mode commuting often centers on one type of rapid transit, such as regional rail, to which low-speed options (i.e. bus, tram, or bicycle) are appended at the beginning or end of the journey. Trains offer quick transit from a suburb into an urban area, where passengers can choose a way to complete the trip. Most transportation modes have always been used intermodally; for example, people have used road or urban railway to an airport or inter-regional railway station.

History

Intermodal transport has existed for about as long as passenger transport itself. People switched from carriages to ferries at the edge of a river too deep to ford. In the 19th century, people who lived inland switched from train to ship for overseas voyages. Hoboken Terminal in Hoboken, New Jersey, was built to let commuters to New York City from New Jersey switch to ferries to cross the Hudson River in order to get to Manhattan. A massive ferry slip, now in ruins, was incorporated into the terminal building. Later, when a subway was built through tunnels under the Hudson, now called the PATH, a station stop was added to Hoboken Terminal. More recently, the New Jersey Transit's Hudson-Bergen Light Rail system has included a stop there, but it is a relatively long walk from the terminal building. Ferry service has recently been revived, but passengers must exit the terminal and walk across the pier to the more modest ferry slip.

With the opening of the Woodside and Birkenhead Dock Street Tramway in 1873, Birkenhead Dock railway station probably became the world's first tram to train interchange station.

Urban mixed-mode commuting

Public transportation systems such as train or metro systems have the most efficient means and highest capacity to transport people around cities. Therefore, mixed-mode commuting in the urban environment is largely dedicated to first getting people onto the train network and once off the train network to their final destination.

Automobile to public transport nodes

Although automobiles are conventionally used as a single-mode form of transit, they also find use in a variety of mixed-mode scenarios. They can provide a short commute to train stations, airports, and piers, where all-day " park and ride" lots are often available. Used in this context, cars offer commuters the relative comfort of single-mode travel, while significantly reducing the financial and environmental costs.

Taxicabs and rental cars also play a major role in providing door-to-door service between airports or train stations and other points of travel throughout urban, suburban, and rural communities.

(Automobiles can also be used as the centerpiece of a multi-mode commute, with drivers resorting to walking or cycling to their final destination. Commuters to major cities take this route when driving is convenient, but parking options at the destination are not readily available.)

Park and ride

Transport planners often try to encourage automobile commuters to make much of their journey by public transport. One way of doing this is to provide car parking places at train or bus stations where commuters can drive to the station, park their cars and then continue on with their journey on the train or bus: this is often called "park and ride".

Similar to park and ride is what is often termed "kiss and ride". Rather than drive to the train or bus station and park the commuter is driven to the station by a friend or relative (parent, spouse etc.) The "kiss" refers to the peck on the cheek as the commuter exits the car. Kiss and ride is usually conducted when the train/bus/ferry station is close to home, so that the driver dropping the commuter off has a short journey to and from home.

Bus to public transport nodes

Many large cities link their railway network to their bus network. This enables commuters to get to places that are not serviced directly by rail as they are often considered to be too far for walking.

Feeder buses are a specific example of this; feeder buses service local neighbourhoods by taking travellers from their homes to nearby train stations which is important if the distances are too far to comfortably walk; at the end of the working day the buses take the travellers home again. Feeder buses work best when they are scheduled to arrive at the railway station shortly before the train arrives allowing enough time for commuters to comfortably walk to their train, and on the commuters' return journey buses are scheduled to arrive shortly after the train arrives so that the buses are waiting to take the commuters home. If train and bus services are very frequent then this scheduling is unimportant as the commuter will in any case have a very short wait to interchange.

Bike and ride

All around the world bicycles are used to get to and from train and other public transportation stations; this form of intermodal passenger transport is often called "bike and ride". To safeguard against theft or vandalism of parked bicycles at these train, bus, and ferry stations, "bike and ride" transport benefits greatly from secure bicycle parking facilities such as bicycle parking stations being available.

Some train, bus, and ferry systems allow commuters to take their bicycles aboard, allowing cyclists to ride at both ends of the commute, though sometimes this is restricted to off-peak travel periods: in such cases, folding bicycles may be permitted where regular bicycles are not. In some cities, bicycles are permitted aboard trains and buses.

In some cities a public bicycle rental programme allows commuters to take a public bike between the public transport station and a docking station near their origin or destination.

The use of "bike and ride" instead of a car can cut costs for fuel and parking, and some families no longer need to own and operate multiple cars. Environmental benefits can also increase (i.e. less pollution) and reduced traffic congestion can deliver significant cost savings to the city and local government.

Many transit agencies have begun installing bike racks on the front of buses, as well as in the interior of buses, trains, and even on ferries. These transit bike racks allow cyclists the ability to ride their bicycle to the bus/train/ferry, take the mode of transportation, then ride again to their final destination. These types of racks combined with increased bike infrastructure and bike parking have made bike commuting a frequent topic of discussion by cities and local government.

Inter-regional mixed mode commuting

Intermodal passenger transport involving air travel

Airport rail link

Many cities have extended subway or rail service to major urban airports. This provides travellers with an inexpensive, frequent and reliable way to get to their flights as opposed to driving or being driven, and contending with full up parking, or taking taxis and getting caught in traffic jams on the way to the airport. Many airports now have some mass transit link, including London, Sydney, Munich, Hong Kong, Vancouver, Philadelphia, Cleveland, New York City (JFK), Delhi, and Chennai.

Airport–ferry connection

At the Hong Kong International Airport, ferry services to various piers in the Pearl River Delta are provided. Passengers from Guangdong can use these piers to take a flight at the airport, without passing through customs and immigration control, effectively like having a transit from one flight to another. The airport is well-connected with expressways and an Airport Express train service. A seaport and logistics facilities will be added in the near future. Kansai International Airport is also connected to Kobe Airport
