According to Leidos engineer William Martin (left), the demonstration uses a thermal detection camera to identify a pedestrian approaching a mocked-up crosswalk that traverses the USDOT booth. The data is sent to a V2X hub installed above the intersection that broadcasts a standard message set over the 5.9 GHz band. Based on the SAE J2735 pedestrian safety message, the notification is received by an on-board unit in the lab’s vehicle. Already equipped with video cameras and Lidar, the vehicle’s V2X system enhances detection of pedestrians by adding non- line of sight recognition and tracking. Still in development, the crosswalk perception solution is part of the lab’s cooperative driving automation (CDA) program that enables automated vehicles to cooperate through communication between vehicles, infrastructure, pedestrians, cyclists and other road users.
“We’re really focused on how infrastructure can play a role in enabling pedestrian safety,” added Sudhakar Nallamothu (right), CDA program manager for the Federal Highway Administration.
