This article considers a range of capacity restraint methods, together with associated convergence monitoring techniques, which may be used in conjunction with a multiple-routing highway assignment model. In particular, ways in which capacity restraint has been made responsive to speed/demand relationships implicit in two successive assignments in an iterative cycle are described. In addition, the problem of ensuring that the method remains stable as convergence is approached is considered. Though a totally satisfactory method has not yet been found, the best method is shown to be superior to previous methods which used a single assignment on which to recalculate link speeds. /Author/TRRL/
