I was listening to 3AW before. They were talking about reduced speed limits on the freeways (and tollways). Vicroads is claiming that reduced limits reduce crashes as well as improving overall throughput (traffic flow). Now, I only occasionally visit Melbourne, but when I do, if it's peak hour or getting close to peak hour the traffic flow is typically less than 80 klicks despite whatever speed limit is imposed at the time. I am trying to understand why a lower speed limit will improve traffic flow? Surely if you have say, a million cars that if they are travelling slower to get on, along and off the Monash (or whatever road), then the throughput will be lower? Those of you who ride these roads commuting could probably explain this better. But I would have thought that the higher the limit the quicker that the traffic gets on and off the freeways and to their destinations. I would hate it if I had to do 80 klicks all the way from Narre-Warren to the City. I tend to time my trips so it's during the low traffic periods. So it would be doubly annoying that if I'm on a 3/4 lane freeway and there's little traffic and I'm stuck at 80 klicks. Of course, the cynic in me makes me wonder if it's not another ploy to "entrap" people into speeding and hence setting up speed traps to nab 'em. Thoughts, anyone?
