5.1.2 Optim controller
Figure 5.4: Map1- high density - optim control - ATWT
High traffic density The optim control has an ATWT of 235 cycles, but the
total count of roadusers in the waiting queues is 1790, which is more than with
the marching control. The waiting queue for edge-node 0 is only 295 and for
edge-node 1 it is 628. Those values show us that the controller is optimizing the
traffic in one direction, which is the direction of the green wave. Edge-node 5
has a very big waiting queue of 754. This is because the traffic is optimized from
edge-node 0 to edge-node 1 and the destination frequencies of edge-node 5 to 4
is 0.4 and from edge-node 5 turning right is 0.4. What happens is that the lane
from junction 6 to 7 is filled easier and the traffic from edge-node 5 turning right
is blocking the lane for the traffic going to edge-node 4.
Low traffic density The Optim control has an ATWT of 216 and a total waiting
queue length of 481.
