Fast and efficient tolling systems are increasingly being sought by road operators as the network of new toll highways around the world continues to expand. But choosing the right system for bridge tolling is even more important, explains Helena Russell

One of the main arguments for the construction of toll roads - apart from reducing the burden on the public purse, of course - is that it provides motorists with a choice. If drivers are willing to pay the toll, they can use well-maintained highways that are usually less congested than public roads, have fewer junctions, and generally get them from A to B in a shorter time. Once you have passed through the toll barrier, you may not have to stop again for a hundred kilometres or more, until you leave the motorway and pay your exit toll. If the route you are travelling has electronic tagging installed, and you have signed up for this service, you won't have to stop at all, the fee will simply be charged automatically to your account.
