    Wait… Buses typically go 7.1mph but a leading cause is they have a speed limit of 20mph?

      7.1mph on average. That doesn’t mean they never reach the speed limit.

      In theory, increasing the speed limit will also increase the average speed ( as long as they are able to make use of the extra limit).

        True, but if the average is about 1/3 of the limit the issue is likely not the issue. To increase the average by increasing the upper limit would require a massive increase. If many buses are being slowed by a 20mph limit, how many must be less than 3mph to get a 7.1mph average? If we fix those 3mph and bring them to 6mph imagine how much the average would increase…

          I wasn’t suggesting that increasing the limit would be a solution to the issue, only that it could (mathmatically) increase the average speed.

          I don’t think anyone is suggesting that 20mph limits are solely to blame, and certainly not a “leading cause”.

          On a side note - Is 7.1mph average in a busy city even that slow for a bus? Considering they have to be stopped for several minutes to let people on/off and stop regularly for red lights.

          I’d be interested to compare to the bus’ average speed to a car taking the same route.
