6.6.3 Stop Sign Control
Intersection approaches controlled by STOP signs are modeled in VISSIM as
a combination of priority rule and STOP sign. A STOP sign forces vehicles to
stop for at least one time step regardless of the presence of conflicting traffic
while the priority rule deals with conflicting traffic, looking for minimum gap
time and headway etc. Dispatch counters (e.g. customs clearance) represent
a variant of STOP signs with a dwell time distribution assigned additionally.
STOP signs can be used to model the following:
► Regular STOP signs: Additionally to the STOP sign a priority rule has to
be defined to make sure, that traffic flows are regarded accordingly. The
STOP sign and the stop line (red) should be placed at the same position.
