Connected Vehicle Demonstration

On August 30, 2016 toXcel organized a demonstration on how Connected Vehicle technologies will benefit emergency responders. This event, held at Penn State’s Larson Institute test track and in conjunction with the ITS Pennsylvania and Mid-Atlantic ITE Annual Meeting, featured two demonstrations: the Volvo Connected Truck and its automatic engine breaking system and Southwest Research Institute’s Emergency Vehicle Alert application. Over 100 responders and transportation professionals attended the demonstration and rode in both the Volvo Connected Truck and in Southwest Research Institute’s vehicles to see up close how the alert systems worked. The National Operations Center of Excellence (NOCoE) filmed the event and is providing the video to the left.

Thank you to NOCoE, Gannett Fleming, Volvo Trucks, Southwest Research Institute, Penn State, Pleasant Gap Fire, Tennis Towing, Skyline Technologies and WTI for all their help!
