Kapsch TrafficCom has completed the implementation of a Low Emission Zone (LEZ) in Castellón de la Plana, a city of 171,000 inhabitants on the Mediterranean coast of Spain.

Reportedly, the company has also provided a solution that includes various technological components to identify vehicles entering and leaving the LEZ, as well as the software to operate and monitor the LEZ and integrate it into the city's mobility management system.

The system is includes a number plate recognition system, air quality sensors, sound level sensors and a signalling system to inform users. The entry and exit points are monitored by 45 optical character recognition (OCR) cameras, which are capable of reading vehicle number plates and performing video analysis to classifies vehicle types including lorries, buses, vans, cars, motorcycles and mopeds.

In addition, there are a further 6 OCR cameras located in public car parks within the ZBE to monitor vehicles that enter these car parks while 24 sensors have been installed to measure air pollution and noise levels in areas that have high levels of traffic and in sensitive locations, such as schools.

The data will be integrated into the city's mobility management system. In addition, the existing EcoTrafiX system, which currently manages traffic in the city, has been updated to provide new tools and additional data that will improve multimodal traffic control strategies.

Additionally, 22 fixed and variable message signs will provide information on the access restrictions and display data related to on air quality, among other indicators. The project also introduced a dedicated mobile application to facilitate user authorization and provide information about the LEZ to citizens.
