COMPASS High-Volume Intersection Study

Ada County (Boise), Idaho - 2007 to 2008
Don Matson, COMPASS | 208-855-2558 ext. 230

Avenue Consultants was the innovative intersection and operations analysis LEAD for the team that competitively won this project from COMPASS (an MPO for the Boise, Idaho area) to evaluate ten of Ada County’s most congested intersections. The goal of this project was to identify innovative intersection treatments that would reduce the congestion and the delay at these ten high-volume intersections. As part of the study team, Avenue brainstormed and developed concepts that were then evaluated with detailed micro-simulation models (mainly VISSIM). These models provided a means to communicate the operations of the new intersection treatment and to accurately evaluate the operations of the intersections. From these evaluations, Avenue identified the operational improvement and benefit of the proposed treatments and developed volume capacity thresholds to help define a lifespan for each intersection. The primary deliverable was a series of graphics illustrating the concepts for each intersection along with other key elements such as cost, delay reduction, impacts, and traffic volumes. The study was well received by the planning organization and is receiving further discussion related to potential implementation.
