ATCS
Adaptive traffic control system (ATCS) is a traffic management strategy in
which traffic signal timing changes or adapts based on the changing arrival
patterns of
vehicles at each intersection. During the process a traffic signal provides
green time to each intersection. As arrival patterns change from cycle to
cycle the length of green time provided to each approach also changes. The
main goal of ATCS is to adjust the timing of traffic signal at intersections
in order to dynamically adapt in real time to prevailing conditions. It
works by responding to data collected from the vehicle detector at each
intersection ATCS can effectively adjust to expected timings in traffic
signal intersection. The ATCS is designed to reduce travel times for
individuals thereby minimizing wait times at intersection and avoiding
collisions.
ATLAS Traffic controller needs vehicle occupancy data at the traffic
intersection to perform ATCS
operation. Therefore, the vehicle data will be collected from the vehicle
detector
devices or CCTV Cameras placed at each intersection and these data will be
sent to
the ATLAS controller to make decision. ATLAS Controller will make
incremental
adjustments to the traffic signal timing based on cycle by cycle changes in
traffic flow
at each intersection. ATLAS will calculate the signal timings by selecting
the most
appropriate
1) Cycle time
2) Phase timings and
3) Next Phase to
execute
4) Split and offset timings
