Intersection Conflict Warning Systems (ICWS) are used to warn drivers on the mainline road of the presence of traffic at stop-controlled intersections and/or warn drivers at stop-controlled approaches of the presence of traffic on mainline roads. ICWS deployments are still relatively new with few deployments prior to 2010, however the number of deployments has increased in the past several years nationwide.
The ENTERPRISE Pooled Fund Study has completed several ICWS related projects from 2011 - 2015 including design and guidance for ICWS, system engineering documents for ICWS, and overall coordination and outreach with national standards groups, industry associations, and other pooled fund programs. Building off these previous efforts, ENTERPRISE conducted this project to identify and document issues related to the development and deployment of next-generation approaches to ICWS. This information was utilized to develop a roadmap of prioritized next steps to help guide future ICWS deployment efforts.
