A method, a system and a computer program product are directed towards determination of a variable toll for a particular target vehicle using a particular point-to-point travel segment of a particular toll road. The variable toll is calculated predicated upon a deviation of an instantaneous point-to-point traffic volume for the particular target vehicle exiting the toll road in comparison with an arbitrarily determined baseline point-to-point traffic volume. The instantaneous point-to-point traffic volume includes vehicles traveling at least a portion of the same point-to-point travel segment as the target vehicle during an effective time interval when the target vehicle traveled the point-to-point travel segment.
