| Summary: | Transportation demand has increased in the last few decades as human activities
increase. One of the most negative impact is the increasing level of traffic
congestion. A possible short-term solution for this problem is to utilize an
adaptive traffic control algorithm. Most of the traffic control systems in Indonesia
still utilize classic control algorithm with a predetermined green phase sequence.
In this study, an adaptive traffic controller is proposed using a Reinforcement
Learning algorithm. Reinforcement Learning algorithm will be applied into
SUMO traffic simulation software.
In designing control algorithm, a Reinforcement Learning algorithm called Deep-
Q Network (DQN) is used. The action taken by DQN is to determine the traffic
phase with various rewards, ranging from pressure to providing adaptive loads
on pressure and queue length. DQN-based control algorithm with adaptive
reward mechanism provide the best performance via vehicle throughput as much
as 56,384 vehicles, followed by classic and conventional control method such as
Webster (50,366), Max-Pressure (50,541) and Uniform (46,241). The increment
of vehicle throughput in a region will increase the region productivity.
