Not sure if there is a formula to figure that out or not, being that there are so many different variables. Material thickness, joint design, preheat, voltage/amperage, type of steel, process, position, and skill of welder. But yes, the larger the diameter, the higher the deposition rate, so travel speed usually goes up as well.

Stick welding?
I did some tests and measured the parameters of every welder at my company and travel speed, to graph the relationship between travel speed and voltage, or travel speed and WFS. Very interesting, allowed me to accurately guess travel speed of a welder by looking at their machine settings. But that was all MIG and wire size was a constant
My instinct tells me that changing the electrode size which changes the metal deposition rate and heat input would require changing travel speed. This will vary from joint to joint and depends on other factors.
