Then, a convergent trial-and-error method for the optimal toll pattern is developed, which is numerically verified by a network example.

It should be noted that this value-of-time is actually not needed when the trial-and-error method proposed below is used in practice.

The objective of this article then becomes to find a trial-and-error method for such an optimal toll pattern based on only traffic count data, which can be easily gathered based on the V2I facilities on the road side.

It is shown in the following section that a trial-and-error mechanism can be built based on the solution algorithm for the VI model (8).

For example, additional studies testing the effectiveness of stimulus-modification procedures to response-prompting prOcedures probably are not needed, nor are additional studies comparing stimulus modification or response prompting strategies to error correction and trial-and-error.

The data are fairly consistent that the stimulus-modification procedures will be more efficient than response-prompting strategies, and response-prompting-strategies will be more efficient than error-correction and trial-and-error procedures.
