>>1111651>How often bus routes actually change?Very frequently, subjected to traffic accident, social events, varied demand origin at different time in a day, road repairance work, etc. If you are talking about more permanent route change, then I think perhaps once per every one or two months that there would have some route changes affecting my locale?
>Traffic that would justify overhead cable instead of battery electric busI think it depend a lot on local labour cost and thus construction and maintenance cost? Could also mean never in some places
And, to use powerlines to replace battery, you need to extend those infrastructure to the farthest end of your network even when those ends are reached only very rarely, in order to free your system from buying battery bus.
80-100 miles is enough for round trip inner city operation if recharging facility is available at terminal but you still need extra spare bus for use when buses are being recharged mid day after completing a round trip. If your bus need 2 hours to recharge, have a range of 100 miles, and run on a speed of about 50mph, then you need at least double the amount of bus you usually need to sustain all day service. Although it is not needed for peak hour only operations. There are buses that recharge faster but I think they are using super capacitor instead of battery?
For longer routes to countrysides, that given range might not be sufficient. You also want to have a fair bit spare power to avoid running out of electricity due to congestion.
>Growth area of future conversion to tram/light railIn places where other form of mass transit already exists and bus are used as complement, this is probably not needed
