Network Coding
Properties & Options
The properties of a desired speed decision can be accessed by
► selecting the corresponding link/connector and
► double-clicking with the left mouse button on the desired speed decision.
● No.: Unique identification of the
desired speed decision.
● Name: Label or comment
● Lane: Lane position within the
link
● At: Link/connector coordinate.
● Time (from/until): Defines the
time interval to which the
desired speed decision refers.
● Label: When showing labels (names) of all desired speed decisions
(cf. VIEW - NETWORK ELEMENTS...) this option allows to individually switch
off the label of that desired speed decision.
● Vehicle Class - Desired Speed Distribution combination: For each
relevant vehicle class one data line needs to be defined. It includes the
desired speed distribution to be assigned to vehicles of that class as they
cross over the desired speed decision. Use EDIT, NEW and DELETE to
create, modify or remove a data line.
Vehicles of classes that have not been selected for a desired speed
decision remain unaffected.
The combination of vehicle classes and speed distribution of the desired
speed decision that was edited recently is used as a default when a new
desired speed decision is added.
The desired speed decision defines the position where vehicles intend to
change the desired speed (not where they reach it). Thus the phase of
acceleration or deceleration takes place after the vehicle has passed this
decision point. Depending on the current speed, the vehicle reaches its
new desired speed at some point downstream.
