CHAPTER 6. CONCLUSION

• For the green wave controller it was needed to specify which roads have
priority to others. The big traffic flows can be set with this property.

• When traffic lights change, there has to be a period of time where all lights
stay red. Road users on the junction can leave the junction during this pe-
riod.

• Five traffic light controllers are implemented: 3 self-organizing controllers
and 2 non-self-organizing controllers.

6.2 Self-organizing traffic light controllers

The proposed self-organizing traffic light controllers of Carlos Gershenson have
been tested on 2 imaginary scenarios and on one realistic scenario: Wetstraat of
Brussels. Those controllers are sotl-request, sotl-phase and sotl-platoon. Two non
self-organizing traffic light controllers, marching and optim controller, have been
implemented and tested on the same scenarios.

The results of the simulations are given in ATWT and TWQL. ATWT stands
for Average Trip Waiting Time and TWQL stands for Total Waiting Queue Length.

6.2.1 Scenario 1

The first scenario is an infrastructure of 2 junctions, 6 edge-nodes and 7 roads
(two directions). Two different traffic densities are used for the simulation: high
density (HD) and low density (LD). The traffic flow in this scenario is symmetric
for opposing edge-nodes.
