      abstract = {In this paper a method is proposed to enhance traffic  assignment process in traditional
travel demand forecasting  models. In this method link delay is calculated as a  function of
flow on that link as well as flow on adjacent  links, using intersection delay calculations.
This method  employs a combination of Frank-Wolf and the method of  successive
averages to model multi-path vehicle assignment  in a reasonable amount of
computational time, for small and  medium size transportation networks.
Inclusion of  volume-based intersection delays in regional planning  models is not yet
widespread in practice. The objective of  this paper is to consider the impact of  volumebased
(dynamic) intersection delays on multi-path  traffic assignments in medium size
transportation networks.  The approach selected is designed to provide more  realistic
results than those generated by models represents  only link delays, due to considering
flows on other links.  Convergence has been an issue in assignment models that  use
intersection delay. Nevertheless, convergence has been  observed in a reasonable amount
of time in our model.
The  results of this paper suggest that intersection delay, as  especially at unsignalized
intersections where delays at  minor legs are highly dependent on volumes, result  in
significantly different assignments. It has been also  demonstrated that the model achieves
a higher levels of  calibration and it is more sensitive to intersection level  policies.},
