If you had to write the ideal specification for a Rapid Transit System it would probably look something like this:-

 The Ideal Specification:-

1. Fast.
   
2. Low fares.
   
3. 24/7 Availability.
   
4. No timetables.
   
5. Convenience.
   
6. Dramatically increase the number of people using public transport.
   
7. Reduce car numbers on roads (less traffic congestion).
   
8. Reduce fuel consumption.
   
9. Reduce pollution.
   
10. Reduce car parking problems.

The Ideal Solution:-

1. Faster than travelling by car.
   
2. Minimal waiting time (eg 5 minutes max).
   
3. As accessible as a bus system.
   
4. 24 hours per day operation.
   
5. Highly computerised.
   
6. Extensive network.
   
7. Security for passengers.
   
8. Low construction cost (= low fares).
   
9. Low operating costs (= low fares).
   
10. Minimal impact on existing infrastructure during construction.
    (lower construction costs + less inconvenience to the public)

BINGO!
