Imagine two cities at a considerable distance from each other. Both centres have the lay-out and use of our cookie model. How works their mobile interrelation? How could you move from the one centre to the other? The real situation will probably be a mix of different scenarios.
Scenario 1: the classic mobility chain.
This scenario might solve the problem of the inner city, but makes it very difficult to reach. There are too many modal changes and the fluidity of the system largely depends on the capacity and frequency of the different modes.
Scenario 2: large scale public transport.
This scenario is probably the wet dream of every goat-woolly environmental activist. The problem here lies in its frequency, but even more in flexibility. We are so used to the car that giving up it’s advantages is no solution at all. It does not fit individuality and fluidity of personal transportation.
Scenario 3: extension of mediating mobility.
This scenario starts from scenario 1 but tries to eliminate a modal step. Could it be possible that certain pod-like vehicles are designed to operate within as well as outside the cores? Considering their service as a commodity and its ease of use thus guaranteed, this might be a viable solution. Bringing the park & ride zones closer to the white zone, for example by reconsidering storey car parks at the city’s edge, is worth an investigation too. But the latter option intuitively feels more complex to implement. As in many cases, a mix of both might be the answer. If price is a decisive factor, different parking rates could manage flows too.
Scenario 4: intercity dedicated lane.
This scenario takes it one step further: would it be possible to connect two cities by using their own internal new vehicle typology? If a vehicle leaves the safe cookie, it enters a dedicated lane on the highway that goes straight to the next metropolis. This dedicated lane could be shared with other 100% driverless vehicles, such as the latest generation of the Google car.
