Thank to technology,a new kind of toll road is likely to become more popular in the future.The new toll roads will not have toll booths.As the driver approaches the toll road,an overhead sigh will indicate the face.A second sign at the entry to the toll road will contain a tiny electronic device that will record the driver's identification number that is attached to the car's rear-view miror.the driver's account will then be billed automatically.If a car does not have an identification card,a camera will photograph the car's license numberv,and a fine will be sent to the violator by mail.
