• Abstract:
  This application was identified as a promising rural Intelligent Transportation Systems (ITS) solution under a project sponsored by the Federal Highway Administration (FHWA) and the ENTERPRISE program. This summary describes the solution as well as opportunities for expansion into the broader context of rural ITS. Traffic signals disrupt the progress of emergency vehicles by causing them to slow or stop. Since other vehicles in cross traffic often appear to have the right of way, hazardous situations often occur at intersections. This simple solution pre-empts traffic signals to give equipped emergency vehicles the right of way. Although various types of pre-emption systems are in use in urban areas across the U.S., the solution described below is an example of a low-cost siren-activated system. As it requires minimal additional equipment, it is suitable for small communities. The example described below is a product manufactured by a particular vendor.
