A leading proponent of Vehicle-Infrastructure Integration (VII) technology, Southwest Research Institute will be demonstrating its latest vehicle collision technology in front of the Javits Center.
The demo will show how two DSRC-equipped vehicles can share information, helping to prevent collisions with objects that are briefly out of sight of one of the drivers.
According to Josh Johnson of Southwest Research Institute, the demo starts with the two vehicles travelling north on 11th Avenue when one of the cars tries to pass the other, hiding a pedestrian that is attempting to cross the street. The pedestrian is willingly played by Shelley Row, Director of the U.S. Department of Transportation”s ITS efforts.
As Row crosses the intersection, she is detected by laser sensors mounted in the lead car”s front bumper. That information is relayed to the passing car, despite that vehicle”s inability to pick her up due to a lack of line-of-sight. The driver is alerted that a pedestrian is crossing its path, preventing a potentially deadly accident.
The demonstration uses advanced VII technology based on the 5.9 GHz standard and relies on predefined routes created from GPS coordinates.
If an unidentified object lies across the roadway network—whether it be a pedestrian, another vehicle or a roadway hazard—the sensors will alert the driver and advise them to take evasive action. DSRC-enabled vehicles can share information (as in the Southwest Research Institute demonstration), identifying objects that fall outside a particular vehicle”s sensor range.Southwest Research Institute is also showcasing its traffic management software that is in operation in Texas and Florida. The fully-integrated solution analyses data from multiple sources—roadside sensors, traffic lights, ramp metering, weather instruments and other data collection units—and disseminates it to police, break-down assistance vehicles and traveler information web sites.
