Pre-Timed and Coordinated Traffic Controller Systems Based on AVR Microcontroller
Abstract: The major weaknesses
of traffic controllers in Indonesia are unable to accommodate the variety of
traffic volume and unable to be coordinated. To solve the problem, a pre-timed
and coordinated traffic controller system is build. The system consists of a master
and a local controller. Each controller has a database containing signal-timing
plans that would be allocated to manage vehicle flows. To synchronize the
signal-timing, the master controller sends the synchronization data to the
local controller wirelessly and the local controller shifts the end of a cycle
by adding or subtracting the green interval of any phases. The transition time
for synchronization only takes one to several cycles. The algorithm for
controlling the traffic including coordination can be done by an AVR
microcontroller. Memory usage of the microcontroller is lower than 10%
meanwhile the CPU utilization is no more than 1%, thus the systems could be
widely developed.
