TRANSYT-7F
Release 10.3 Known Issues Please contact McTrans with any new issues raised that may be added to this list. 1. When coding link
connections (on the Map View or the Edit > Feeders screen),
automatic flow balancing does not work properly if the summation of
upstream left-turn and right-turn volumes exceeds the downstream thru
volume. In this situation, it might be necessary for the user to
manually code feeding flows in the Feeders screen.* 2. When importing a
CORSIM input file into T7F10, two-way stop-controlled (TWSC)
intersections are not imported. The next version of TRANSYT-7F
will allow the user to import TWSC nodes if desired, or import
signalized intersections only.* 3. In the time-space
diagram screen, efficiency and attainability are not computed correctly
when progression bands "wrap" at a two-way stop-controlled (TWSC) node,
such that the "bottom" band is above the "top" band at the TWSC node.* 4. In the Lane
Configuration screen, if volumes are coded prior to lane
channelizations, subsequent changes to the lane channelizations might
automatically change the volumes. This might make it necessary to
re-code some of the volume data (i.e., volume, peak hour factor, and
turn bay storage).* 5. In the Route
Summary Report, the route-wide Disutility Index (DI) is not computed
correctly for the first route in the data file. To get around
this problem, the DI for route #1 could be computed manually, by taking the
summation of link-specific DI's within the route.* 6. When importing a CORSIM input file into T7F10, T-intersections operating under actuated control are sometimes not assigned the correct approach direction (NB, SB, EB, WB). This does not affect the ability to perform direct CORSIM processing or optimization, but if the user tries to perform a macroscopic TRANSYT analysis, volumes and timings might be assigned to the wrong approach.* *Indicates that this issue will be resolved in the next software release.
