Smart Traffic Signals: Lee's Summit, MO Case Study
•
3 likes•530 views
This document summarizes a case study of implementing adaptive traffic signal control technology called InSync in Lee's Summit, Missouri. It showed reductions in delays, stops, travel times, emissions, fuel usage, and crashes compared to the previously used coordinated traffic signal plans. The technology uses detection inputs and optimization models to intelligently control signals. It has been deployed in many cities across the US with consistent benefits.
