JTRP Technical Reports

This study develops an enhanced transportation planning framework by augmenting the sequential four-step planning process with post-processing techniques. The post-processing techniques are incorporated through a feedback mechanism and aim to improve the stability and convergence properties of the solution, thereby improving the reliability of the planning process. There are three building blocks of the proposed post-processing module: slope-based multi-path algorithm or SMPA, perturbation assignment, and O-D prioritization technique. SMPA is the most important part of the module and it can be used as both a post-processing algorithm and an independent static traffic assignment algorithm. In addition to SMPA, the post-processing …
