• Abstract:
  This document serves as a use case for conducting Benefit-Cost Analysis for a hypothetical adaptive signal control project. Adaptive signal control adjusts the timing of red, yellow, and green lights to accommodate changing traffic patterns and ease traffic congestion. The main benefits of adaptive signal control systems compared to conventional signal systems are that they can: (i) continuously distribute green time equitably for all traffic movements; (ii) improve travel time reliability by progressively moving vehicles through traffic signals; (iii) reduce congestion by creating smoother flow; and (iv) prolong the effectiveness of traffic signal timing. By receiving and processing data from strategically placed sensors, adaptive signal control can more effectively manage the flow of traffic through intersections.
