Re: Re: Adelaide [Was: Gold Coast trams at standstill with long delays after system failure ]

It is just plausible that the current limit has been reached because of the 5 to 10 minute headway. Suggest that if the headway
were reduced to 3 to 6 minutes (a) if patronage did not increase, overcrowding would be eliminated and people would be happier (b)
much more like patronage would increase till a level of overcrowding were reached, not as bad as at present, but still at the
balancing point between "Should I take the tram or the car?"

Is the GCLR at the limit as far as overcrowding is concerned? If so, perhaps headways at the times of greatest demand could be
reduced. Am I correct in thinking that if headways were reduced from the current 7.5 minute to 6 minutes, patronage would increase?
This demands that all available trams are used, and it also demands that down time at termini is cut - yes, this means a difficult
in recovering if there is any delay, but with more trams dwell times are likely to be slightly reduced making the journey faster
anyway.

With the current 34 min end to end, and, say, a 4 minute layover at each end, a round trip is 76 minutes (perhaps 10 trams on a 7.5
minute headway with some scrimping). With a 30 second turnaround (changing drivers) and a one minute saving en route, the round
trip is 67 minutes, 11 trams on a 6 minute headway with the same scrimping. Almost certain it would be possible to improve traffic
light priority on the route.
