POSSIBLE PASSER II ENHANCEMENTS

The PASSER II computer program for optimization of arterial signal timing has been accepted by usage. It has been used extensively during the last few years. The program's ability to select multiphase sequences for a maximum bandwidth progression solution has led to its increasing use and application. The PASSER II maximum bandwidth solution has been well accepted and implemented throughout this country. The theory, model structure, methodology, and logic in the PASSER II computer program has been evaluated and documented. An evaluation was undertaken to determine if several enhancements to the PASSER II program as related to a revised green split procedure, a minimum delay cycle length, and number of alternate optimal solutions could improve the utility of the solution and would be useful measures. The comparison was to the existing PASSER II computer program and comparison TRANSYT program runs. This evaluation showed, for the three scenarios considered, that a revision for the green split routine provided equal saturation splits. An advisory minimum delay cycle length calculation would provide useful guidance in the selection of the cycle length range to consider. Other measures, like a minimum delay performance measure, alternate optimal solutions, and improved delay measure, could provide useful results. (Author)
