Columbia develops smart VRU headphones

The Data Science Institute (DSI) at New York’s Columbia University is designing an intelligent headphone system that uses miniature microphones and intelligent signal processing to detect sounds of approaching vehicles.

The institute says the system will be able to send an audio alert to the pedestrian’s headphones if a hazard appears nearby. The headset will also include a low-power data pipeline to process sounds near the pedestrian. This pipeline will also contain a custom integrated circuit that extracts relevant features from the sounds while using little battery power, the institute adds.  Machine learning models on the user’s smartphone will classify acoustic cues from city streets and nearby vehicles to warn users of danger.

    IRD, Inc's Terry Bergan discusses future applications of weigh in motion technology. The application in recent years of Weigh In Motion (WIM) at tollgates has been driven by recognition of the fact that there is economic value, which can be levied, attached to Heavy Goods Vehicles (HGVs) which haul laden (and are therefore heavy) rather than empty. As wear and damage to road surfaces increases exponentially with weight, the targeting of HGVs in particular makes sense from both the economic and maintenance p

    An innovative ‘pothole alert’ research project could potentially save motorists billions of pounds in punctures, vehicle damage and road accidents every year, say researchers. Jaguar Land Rover is researching a new connected car technology that will allow a vehicle to identify the location and severity of potholes, broken drains and manhole covers, and then share this data in real-time via the cloud with other vehicles and with road authorities to help them prioritise repairs.

    What future is there for automatic number plate recognition? Will it be supplanted by electronic vehicle identification, or will continuing development maintain the technology's relevance? In recent years, digitisation and IP-based communication networks have allowed Automatic Number Plate Recognition (ANPR) to achieve ever-greater utility and a commensurate increase in deployments. But where does the technology go next - indeed, does it have a future in the face of the increasing use of, for instance, Dedi
