Hello,
Concerning my PhD project, I'm curious about the placement of electronic toll stations within a city, particularly in Europe. I'm interested in whether they are typically situated sequentially along one or more routes, arranged in a grid network, or perhaps organized in a circular pattern.
I am also wondering if all electronic toll stations in a city are typically connected to each other through the available links among them, or is there any possibility that two or more toll stations are not connected (in a city)?
Thank you in advance for your help.
