Which controller did the 2070 supersede?

Answer: C — Model 170 controller

The 2070 controller is known to have superseded the Model 170 controller. This advancement was part of an effort to improve traffic management systems by providing enhanced features and capabilities. The 2070 controller offers greater processing power, improved traffic signal control strategies, and better flexibility for integration with various traffic management systems compared to its predecessor. The Model 170 controller was widely used in traffic signal control before the introduction of the 2070. The transition from the 170 to the 2070 reflects advancements in technology aimed at addressing the increasing complexity of modern traffic patterns and the need for more sophisticated traffic signal control solutions. The 2070 controller is designed to meet these needs while maintaining compatibility with existing infrastructure, which makes it a significant upgrade over the Model 170.
