A suggestion : Statistics
It could be interresting to get various real time and global statistics, such as :
- Load ratio (percentage of used seats in the cars) (can be displayed at the network level, a line, or a station)
- Average transport distance (Average distance crossed by each traveller, can be given at network level, or for a station, for the travellers going from or to the station, or at network level per passenger categories))
- Average waiting time (at network, line or station level)
- Number of people in transit (people change line at a given station. It could be a the network, line or station level)
These data could be provided real time, or the average/sum during the whole game (It could also be plotted against time).
This could be interesting, but would it be useful information for the amount of clutter introduced (and work involved making it legible)?
