Modeling stop signs and toll counters

Model stop signs on access roads to intersections with a combination of right-of-way control and stop sign.

Priority rules account for conflicting traffic as well as for the minimum clearance and gap time. Stop signs, however, make vehicles stop for at least one time step, independent of whether there is conflicting traffic or not.

Conflict areas also take desired acceleration, maximum acceleration as well as the vehicle length of the two vehicles in both streams into account and reflect the driving behavior better than priority rules (It is better to use conflict areas than priority rules to model driving behavior.).

Toll counters are a variant of stop signs that are additionally assigned a dwell time distribution value.

Stop signs can be used for the following modeling scenarios:

• Regular stop sign: You need to define a stop sign and a priority rule. Position the stop sign at the same position as the stop line (red) of the priority rule (Modeling priority rules).
• Signal controller with turn on red: Right turns are allowed in spite of a red signal. In the Green arrow tab, select Only on red, to enable the stop sign only when the selected signal group of the selected SC indicates red.
• Toll counter, e.g. customs office or toll gate: Vehicles stop according to the time distribution defined in the attribute DwellTmDistr (Dwell time distribution). On the Time Distribution tab, select Use time distribution (UsesDwellTmDistr).
