Ralph Menzano takes us on a fascinating journey into the world of smartphone-based tolling — a way to increase road-based revenue, help cities control peak-time congestion, and (at long last) enforce HOV lane use. Next-gen toll systems not only cost less than RFID-based ones, but have the potential to reduce the number of cars on the road, replace gas-tax revenue lost due to EVs, and provide a mountain of information to transit authorities to help them better manage traffic. Menzano offers a success story from a pilot program in Texas, USA; looks at how the US has fared against Europe and Asia in tolling; and helps us understand why much of the world is looking to the US for leadership in usage-based road pricing for light vehicles.
