New Sensor Concept for Intra-Frame Speed Measurement
Traffic management plays an important role in the smart city concept, enabling the authorities to observe and control the traffic flow. The key elements of such system are the sensing nodes, which provide information regarding the speed of each individual vehicle. Current speed measurement devices use separate sensors for speed estimation (RADAR/LIDAR), and vehicle identification (camera). These are expensive devices, and thus not suitable for example, to monitor the whole road network of a city, which would require a large number of sensing nodes. The research is aiming at the development of a vision based speed measurement concept, which offers a single CMOS imager for both speed measurement and license plate recognition.

The ongoing research is focusing on a novel vision based speed measurement device. We named two research directions: theoretical research consisting of mathematical model of the method and proof of concept measurements; and the design of a dual-pixel CMOS imager, based on the theoretical results.
Based on the published research results, a compact, low-cost camera system will be developed, capable of capturing two separate images in parallel, providing information for vehicle identification and velocity measurement, using a single sensor.
