This study analyzed the impact of emergency vehicle traffic signal preemption across three coordinated intersections on Route 7 (Leesburg Pike near Landsdown) in Virginia. Emergency vehicle signal preemption is a preferential treatment technique used to ensure continuous green phases to emergency vehicles (i.e., ambulences) at successive signalized intersections on arterials. It may reduce the time necessary for ambulances to reach a victim or emergency facility, poviding faster, life-saving 911 response. However, the impact of signal preemption on the time-based coordination (i.e., synchronization) of an arterial is not well documented. In summary, this study effectively quantified the effect of emergency vehicle signal preemption on the coordination of a signal system for the conditions studied. The information contained in this report may be of assistance to public agencies considering the installation of emergency signal preemption systems and to Intelligent Transportation Systems engineers.
