Urban APM systems range from the city center to suburbs and new towns. The city center is typically the liveliest part of the city, combining working, living and entertainment; attracting large transportation flows. Suburbs and new towns by contrast are typically low density with modest transit flows. In all cases, the transportation flows shape today’s city districts.
In some cases the need for public transit is even more apparent; many cities are now creating car-free, or car-accessibility reduced, city districts (www.carfree.com). Ec0-towns, such as Masdar City, accommodate mobility with alternative transportation. Environmentally friendly, innovative means of transit fit perfectly with the vision of a car free city.
Ultimately an interconnection between origin and destination, whether with a single or multiple mode of transit, is required to provide door-to-door transit and to avoid people resorting to use of their car. Lighter, more affordable and flexible transit systems, such as Automated Transit Networks, can provide a solution for city centers, suburbs and new towns.
ATN systems address the weakest link in the transportation chain: the last mile. The walking distances to access public transit become shorter, while the stations for the corridor transit systems can be spaced further apart. This allows for the average speed of those systems to be increased. As such, by addressing the last mile, the transportation chain as a whole is improved.
Through a network of guide ways PRT allows for individual, direct origin to destination transit. PRT systems can feature a high station density and network typology, improving the accessibility of public transit. The narrow guideway ensures that is easily integrated both in city centers and suburbs.
The GRT system can function as a feeder system to public transit nodes. It can either provide a high capacity operating at a short headway, or minimize costs by reducing the fleet size and spatial impact.
