Posting from the City Terminal in Stockholm, so this will be short...

I don't think 31 km /h is that unrealistic either for big cities...

I believe most metropolises in the world have an even lower average speed downtown...

Wasn't that of London something lilke 10 km/h before the congestion charges?

Besides, since the cities in SC4 are smaller than in RL, with shorter routes from home to work,

sholdn't the speeds be smaller than in RL, rather than larger?

Regarding the advantage I was trying to explain about having smaller network speeds...

Consider a Sim searching for the fastest way to work...

The straight path leads to a railway station.

From there he can choose two equally long alternatives, rail and road, both being 40 tiles long.

In the other end, there are 3 more tiles from the railway station to his job.

In eiher alternative he would take the car to the first railway station.

Then he'd have to choose. Park the car and take the train or drive on?

With Maxis' Simulator the train would take 40/110 = 0.36

The walk from the train to work would take 3/3.5 = 0.86

Thus, the total time from the first station to work is 1.22

By driving he would get there in (40+3)/31 = 1.39

This means that he would take the train if each station

would have an entry cost of no more than (1.39-1.22)/2 = 0.085

Now, consider the city upgrading the roads and rails to Simlator Z.

The train would now take 40/150 = 0.27

And the walk to job would take 3/5 = 0.60

Total time from the first station = 0.87

By driving he would now get there in (40+3)/50 = 0.86

Thus, regardless of the entry cost of the station, he would probably not consider taking the train, unless road congestion makes that route considerably slower.

And Simulator A would be even worse...

This is all theory, but I hope it explains a little better what I meant was the problem when each custom simulator has (proportionally) increased the car speed more than the speed of any MT... and then trying to solve the problem of MT not being used by optimizing the entry costs of stations.

Now, I'm not trying to convince anyone to start changing the Simulators or even adding new ones...

I'm just trying to explain my feelings about some of the problems...

It's a pity Maxis didn't implement the entry cost themselves, if 0.05 may indeed have been what they intended to use...
