Sevilla vuelve a procesionar de manera segura en Semana Santa con la tecnología de Bosch y sus partners

The security device of the Andalusian capital during Holy Week 2019 counts for the second consecutive year with Bosch Security solutions, together with those of Axión, Protelsur and Sitelen Spain, as part of the Smart City project to monitor the flow of people and vehicles.

He Ayuntamiento de Sevilla has launched the Smart City project during its emblematic Holy Week, which again this year features the technology of Bosch Security to ensure the protection of citizens and visitors, together with the solutions of its partners such as Axión, Protelsur y Sitelen Spain.

As a novelty this year, the security project incorporates the so-called Intelligent Crowd Management, que utiliza las cámaras de Bosch como sensores inteligentes que ofrecen información en tiempo real sobre afluencia de personas, aforos virtuales, detección de objetos en velocidad y vehículos pesados en zonas peatonales.

In this sense, destaca la incorporación del análisis inteligente del ruido, junto con detección de coches aparcados en zonas de emergencia o que obstaculizan vías de evacuación para monitorizar la afluencia de personas y vehículos.

Además de la tecnología de Bosch, este ecosistema de seguridad integral se completa con las soluciones de Axión, Protelsur y Sitelén, empresas vinculadas a la innovación y que forman parte del programa Smart City Partners de Bosch.

The information from Bosch cameras and parking sensors is collected by Axión's IoT platform, which is responsible for processing the counting data, alarms and occupancy and sending them to the infrastructure of the Seville city council, responsible for managing the rest of the subsystems such as public lighting, the public address system or emergency messaging.

This company has developed different tools aimed at data processing and coordinated city management, which are used especially when there are large events.

To achieve the greatest effectiveness in people counting, the cameras have been installed at height with a top-down view by the company Protelsur at different strategic points in the city, such as access points to the center, the main evacuation routes and public squares. For your part, Sitelén operates as a certified Bosch technical service for the commissioning and maintenance of the operation.

Bosch parking sensors have been installed in critical areas where vehicles may obstruct emergency exits or evacuation zones. Both video cameras and sensors are connected directly to the Emergency Coordination Center (CECOP) in Seville via fiber optic and 4G connections (LTE) implemented and secured with IP-Sec.

Bosch solutions have been selected for this project because, among other elements, they incorporate embedded video analytics, which allows the cameras to be connected via 4G, WiFi or B-PLC satellite. Besides, These devices have demonstrated their reliability in counting people and detecting occupancy levels, so that it is possible to perform noise analysis and generate alarms based on frequency or decibels.

Bosch cameras also integrate Starlight technology, which provides color vision even under low light levels, as well as extended dynamic range (WDR), capable of optimally managing changes in light and backlighting, both day and night.

Data security (TMP) is implemented in the cameras at the hardware level, they have low data and video streaming storage consumption, as well as the possibility of redundant storage in the camera and in the CECOP. Besides, The parking sensors have dual detection technology and are easy to install.

Intelligent crowd management

Seville's Holy Week brings hundreds of thousands of visitors to the city's historic center, al paso de las hermandades que procesionan desde cada templo hasta la Catedral.

the high concentration of people, combined with the city's architecture in this area (narrow streets with many nooks and crannies) increases the risk of stampedes due to false alarms caused by falling metal objects, shouts or runs by groups of people that, often, are intentional.

This has caused situations of collective panic in recent years that have resulted in stampedes and people being crushed, disruption of the procession, abandonment of images and numerous material damages, in addition to generating a negative image of this event, which is a tourist attraction for the city.

That's why, the Seville City Council has sought technological tools to understand, in real time, the flows of people accessing the center, the level of occupancy of the different sections of the route, possible crowding on evacuation routes, virtual capacity control, the start of races or stampedes, the detection of vehicles in pedestrian areas or incorrectly parked in evacuation zones and the analysis of critical noises.

With this information, in addition to viewing the security cameras live and maintaining permanent communication with the Police, CECOP managers can send live messages to the public via loudspeakers, social media, and Bluetooth beacons, as well as act on public lighting (bringing it to its maximum intensity) or activate Police intervention.

The ultimate goal is to automatically and reliably obtain the degree of occupancy of the different streets in the center, pudiéndose conocer en tiempo real cómo se comportan los visitantes y los vehículos y de esta manera tomar medidas preventivas para evitar situaciones de riesgo para la población. Besides, con las estadísticas de afluencia obtenidas a lo largo de este año se podrán planificar nuevas acciones para próximas ediciones.
