N2 - Previous studies on the new congestion reduction method - tradable credit scheme rely on the full information of speed-flow relationship, demand function, and generalized cost. As analytical travel demand functions are difficult to establish in practice, this paper develops a trial-and-error method for selecting optimal credit schemes for general networks in the absence of demand functions, based on the method of successive average. Comparing with the converging speed of trial-and-error for congestion pricing proposed by Yang et al. (2004), we find that the trial-and-error method for tradable credits converges more slowly, but the generated traffic flows have a much smaller Euclidean distance to the SO flow pattern.
