About this file
The documents detail a traffic signal synchronization project for County Highway NN (CTH NN) involving a 0.81-mile urban corridor with three signalized intersections. The project focuses on fiber optic connections between intersections at CTH NN & CTH EE and CTH NN & Fairwinds Boulevard, with proposed signal upgrades and coordination to improve traffic flow. The project is planned for implementation in 2024, with a posted speed limit of 35 miles per hour and an annual average daily traffic volume of 13,600 vehicles.
The project includes a comprehensive environmental impact analysis using the USDOT Equitable Transportation Community (ETC) Explorer tool, which assesses the corridor's environmental burden. The CMAQ Emission Calculator Tool estimates potential emission reductions from signal synchronization, projecting benefits such as increased average speeds (from 24 to 28 mph during peak hours), reduced travel times, and decreased emissions of pollutants like carbon monoxide, particulate matter, and nitrogen oxide. The environmental assessment for Census Tract 55133203901 shows a total population of 5,200 in the project area, with no disadvantaged census tracts identified.
