The city of Bologna has chosen Wisenet video surveillance cameras to help it create a smart traffic management system. The City wanted to invest in a video surveillance solution which would allow the monitoring of 12 vehicle access gates to the city in order to provide authorities with reliable real-time information about urban mobility. The purpose was to provide a tool to allow authorities to take strategic planning measures and optimally redistribute the traffic load on the road network.
After extensive evaluation of a wide range of possible solutions, a decision was made to procure a total of 89 Wisenet cameras manufactured by Hanwha Techwin. The implemented solution consists of cameras dedicated to vehicle counting and classification, and ANPR cameras which have been installed on strategic gates. The cameras monitor both directions of travel to allow local authorities to study the most important and strategic vehicle access flows to the city.
By integrating high image quality and advanced video algorithms, Wisenet ‘intelligent’ cameras are able to enhance the value of video surveillance by supporting mobility and security in smart cities.
24 of the cameras installed are Wisenet XNO-6120R/TD bullet cameras equipped with Traffic Data, an edge based application developed in cooperation with Sprinx Technologies which facilitates the collection of statistical data about vehicle flow. By tracking the vehicles moving in a camera field of view, the application is able to provide information on vehicle counts, classification and average speed.
24 of the other cameras installed are Wisenet XNO-6120R/FNPs. These feature Roadway Licence Plate Recognition application which is able to help the local authority’s control room operators detect illegally parked vehicles and other traffic infringements. Effective with all European numberplate formats, the application has more than a 95% recognition accuracy whatever the environmental conditions, even when vehicles are moving at speeds of up to 150 km/h.
The Wisenet XNO-6120R is a 2 megapixel bullet camera which is able to capture high definition images with the help of a 12x optical zoom, digital image stabilisation with built-in gyro sensor, a defog feature and built-in IR illumination. Part of the Wisenet X camera series, the XNO-6120R features 150dB wide dynamic range (WDR), to produce clear images from scenes that contain a challenging mix of bright and dark areas and normally result in overexposed or underexposed images. The processing power of the Wisenet 5 chipset incorporated into the Wisenet X series provides an opportunity to run on-board third-party video analytics plug-ins for different applications, such as numberplate recognition, vehicle counting/classification and real time automatic incident detection.
Completing the camera line-up are 41 Wisenet SNP-L6233RH 2 megapixel 23x IR PTZ dome cameras which have been carefully located at major road junctions throughout the city, in order to allow control room operators to zoom in to see close up detail of any incidents.
“We are delighted with how easy it has been to successfully integrate the Wisenet cameras with our existing video management platform and our other supervision monitoring systems,” said Alberto Nuzzo, Head of Office ‘Digital Infrastructure and Telecommunications’, at Comune di Bologna, when commenting on the success of the traffic management solution. “The data captured by the Traffic Data and ANPR applications running onboard the cameras, is allowing us to far better manage the existing levels of traffic, whilst also helping us capture and store valuable data which we will be able to analyse to assist us to plan for the future.”
