Table 5.10: Wetstraat 7am, platoon controller: ATWT values for different values
of θ and φmin. Rows represent different values for θ, columns represent different
values for φmin.
not always predictable. With φmin = 5 the traffic light controller works as
expected but will have a higher ATWT which is still good.
• If θ = 10 and φmin = 1 the first junction of the Wetstraat will interleave
the traffic of the Wetstraat and its side-road. This causes a very high av-
erage trip waiting time and a large waiting queue at the beginning of the
Wetstraat. Behind the first junction the traffic density is much lower and the
next junctions have no problems. If φmin = 5 for the same θ this problem
is solved.
If those ATWT values are compared with the results for the optim control
method (ATWT=358.11), it shows that all values for φmin = 5or10 are smaller
than for optim. The lowest value is only 44.32% of the ATWT value of optim.
The highest value is 63.53% of the optim ATWT value. The platoon controller
with θ = 5 and φmin = 1 has the lowest ATWT (28.14% of optim ATWT), but it
has some unexpected side-effects, which are not acceptable.
If the best ATWT has to be selected without side-effects it would be around
170, which is a reduction in ATWT of 52%.
