- A Matlab program was developed to convert the required inputs and
outputs for TRANSIMS and MOVES by calling the MySQL database, and
running the two models.
- For links within the subarea network, detailed second-by-second vehicle
speed trajectories were used to derive the link drive schedules.
- For links outside the micro-simulated area, emissions were based on the
average speeds.

- Following the last iteration of the stand-alone TRANSIMS model run,
initial EPFs are calculated and fed back into the Router.
- The Router uses these EPFs to start the initial (or first) green routing
assignment. Upon its conclusion,
an updated list of EPFs become available as a result of running the
integrated TRANSIMS – MOVES model.
- The new EPFs are then used by the Router to start a new iteration
resulting in a new set of routing plans.
- New routing plans are compared with previous plans in terms of emissions
reduction (using the “Green Plan Compare” program). Plans improving savings replace older
plans. This continues for several
iterations to approximate green user equilibrium (UE) routing.

- Travelers who choose to use the green routing guidance system are
randomly distributed in the study area.
