Abstract:The Mid-America Regional Council (MARC) and its program area, Operation Green Light (OGL), manage more than 750 signalized intersections across a nine-county region, as shown in Figure 1. Kansas City Regional Signal System OGL staff members analyze and retime corridors when they notice the need for potential improvements, but this awareness is often delayed because of incomplete or untimely data, lack of skills or resources to analyze available data, or inadequate resources to collect new data. Ideally, each agency and traffic signal would be equipped with advanced equipment and functioning detection to support automated traffic signal performance measures (ATSPMs) however, this infrastructure is too costly for all agencies to install and maintain. Some agencies have installed such infrastructure, but disadvantaged communities face noteworthy challenges in terms of staffing and infrastructure, leading to distinct differences in signal management across the Kansas City metro area. A lack of data and resources in any agency leads to inefficiencies in task prioritization, stretching staff time and negatively affecting roadway operations. The two primary needs for OGL and its partners are to better understand and communicate the status of the Kansas City Regional Transportation System.
