Is there a convenient way to calculate the cost of tolls between two arbitrary points within the United States? I'm planning to take a trip along the Eastern seaboard and will be passing through multiple states with different toll-collecting authorities. The mapping and trip planning resources I've found so far will only indicate whether a particular section of road has tolls, not the price of those tolls. I'm aware that the various toll-collecting authorities post their rates online, but these charts are often difficult to use if you're not already familiar with the area. Isn't there an easier way?
If you know your route, you could use CostofTolls.com:
you get the idea.
I have created an iOS app which calculates tolls based on addresses of origin and destination, it's called Tolls Calculator USA: https://itunes.apple.com/us/app/tolls-calculator-usa/id909952082?mt=8
