Showing data about paths of dynamic assignment in lists

You can show data about paths from dynamic assignment in lists.

Note: The Paths list can only be displayed using the add-on module Dynamic Assignment (Using dynamic assignment).

You can save the following data and data formats:

Results of path evaluation

The Paths results list contains the following attributes:

Result attribute Long name

Short name

Definition

Volume (old)

VolOld

Number of vehicles started on the path, including all vehicle types and/or each vehicle type selected during the last iteration for which the Path file was updated.

Volume (new)

VolNew

Number of vehicles started on the path, including all vehicle types and/or each vehicle type selected during the current iteration for which the Path file was updated.

Distance

Dist

Distance
Is detour Is detour Path is a detour

Edge sequence

EdgeSeq

Number of edges in sequence

Edge travel time (old)

EdgeTravTmOld

Travel Time on the edges of the last iteration for which the Path file was updated.

Edge travel time (new)

EdgeTravTmNew

Travel Time on the edges of the current iteration for which the Path file was updated.
Converged Conv
  • True if the convergence condition for the path was met during all time intervals.
  • False if a new best path was found in the current simulation run.

If the Path travel time is included in the convergence condition, the difference between Path travel time (raw data) and Path travel time (old) is divided by Path travel time (old) to determine the percentage change.

To parking lot

ToParkLot

Number of To parking lot

Number

No

Number of path

Static cost

StaticCost

Static cost

Path travel time (new)

PathTravTmNew

Determined average travel time of path:

  • prior to a simulation run: smoothed travel time, aggregated from path file by departure time
  • during a simulation run: changing, incomplete, newly recorded average travel time
  • after a simulation run: travel time smoothed again with the average newly recorded travel time of all vehicles on this path and aggregated by departure time.

Path-travel time (old)

PathTravTmOld

Travel time of previous simulation run, from the start of the simulation run. This value can be used for path search, if in the Dynamic assignment: Parameters window, in the Choice tab, you selected Use volume (old) (Attributes for the trip chain file, matrices, path file and cost file).

Path travel time (raw data)

PathTravTm

Unsmoothed mean travel time of all vehicles started during this interval. Is not saved and is only visible during the simulation run and afterwards, as long as you do not start a new simulation run or reload a route file.

From dynamic vehicle routing decision

FromDynVehRoutDec

Number of last dynamic routing decision of path

From parking lot

FromParkLot

Number of From parking lot

Route guidance vehicle

DestinationVeh

Number of route guidance vehicle
