Traffic assignment by paired alternative segments: An Ohio case study Conference Paper uri icon


  • Abstract This paper examines the performance of a new traffic assignment algorithm, TAPAS, in a case study drawn from transportation planning practice. By identifying and adjusting route and class link flows on pairs of alternative segments, TAPAS is able to converge quickly to the user equilibrium (UE) while finding unique UE route and class link flows, which satisfy a condition of proportionality. The results show that TAPAS achieves more precise solutions compared to a commercial traffic assignment tool based on Frank …
