I wish to propose a new bus structure, based on the hub and spoke concept.
We can have 10 bus hubs which are located at the major towns and next to MRT stations. Examples of the hubs are Ang Mo Kio, Tampines, Jurong East, Woodlands, etc.
There will be feeder buses that take passengers from their home to a hub. These buses run at intervals of 2 or 3 minutes. The travel time to the hub should be less than 15 minutes.
The express buses will connect one hub to another and will run on expressways. For example, it will take 30 minutes for an express bus to travel from Jurong East to Tampines, compared to 120 minutes for a normal bus that has to stop at every bus stop.
The travel time from Ang Mo Kio hub to Woodlands hub will be 17 mins by express bus, compared to 70 mins for a normal bus.
Someone from Jurong West can travel to Pasir Ris as follows:
a) Take the feeder bus to Jurong East hub.
b) Take the express bus to Tampines hub.
c) Take the feeder bus to Pasir Ris.
Apart from a reduction in travel time, the new structure will make it easier for people to travel and can also be an alternative when the train breaks down.
The hub and spoke concept is adopted for air travel. The smaller planes take passengers to a hub and a long distance plane take the traveler to another hub. Container ships also operate on a similar concept.
