Hello,
I'd like to ask you about an expression I found in the text about automatic road tolling system. Here's the sentence:
"This solution is installed adjacent to the lane and requires no in-road equipment or light barriers."
What do they mean by light barriers? Traditional traffic lights (ex. red, yellow, green) or something else?
<<Second question deleted.>>
Thanks a lot!
