The Transport vertical market encompasses all those companies and activities that facilitate the mobility of passengers and goods, both at an urban and interurban level. Specifically, this sector includes rail services and means of transport (trains, trams and suburban railways), road (buses), maritime (ships and ferries) and air (planes), as well as the operational management of infrastructures such as airports. , railway stations and seaports.
If we focus on public passenger transport, in 2021 there were around 4.4 billion people using this type of transport in the world, according to Statista . The fact that this vertical moves millions of people a day makes it one of the most vulnerable sectors, and that is why it requires advanced and specific video surveillance and security solutions to mitigate the risks that this influx of people presents.
In general, the transport infrastructure is characterized by a network of fixed stations interconnected by one or more means of transport, as would be the case of airports interconnected by planes or railway stations interconnected by trains.
Regarding security and video surveillance systems , we find two very different cases: fixed environments in stations and mobile video surveillance solutions for means of transport, each environment having different needs and concerns regarding security.
Stations, airports and seaports for passenger transport are areas with a high influx and continuous movement of people. Therefore, to guarantee security among crowds, reliable images of all critical areas and redundancy systems are required to ensure the uninterrupted operation of the video surveillance solution in the event of any failure situation.
Given the large number of cameras that are needed to cover spaces such as those mentioned, another utility that is increasingly used in the sector is intelligent video analytics . The use of this technology makes it possible to control both the occupation of spaces and analyze the behavior of the crowds, in order to detect any suspicious attitude in time and minimize risks.
In this field, thanks to the constant evolution of the different branches of Artificial Intelligence, there are more and more use cases and the scope of video analytics in Transport. Currently, we find specific analytics for the detection of improper crossing or falling of people in the train track box, even automatically detecting the presence of a train on the track to eliminate any possible false alarm during the boarding and alighting of passengers from the train.
Another analytic of interest for any station, airport or seaport is the detection of high occupancy density, useful for capacity control and real-time detection of crowds. Also very noteworthy for the sector is the use of analytics to detect anomalous behavior such as loitering, intrusions, fraud at turnstiles or gates…
Beyond security, video analytics solutions provide us with multiple data on the behavior of visitors or passengers. The set of data provided by the analytics can range from the number of passengers on a certain platform or boarding gate to the detection of the busiest areas or corridors, the average queue or waiting time, the least active time slots, even segmentation demographic by gender and age of travellers. The consequent analysis of this data allows forecasts to be made and behavior patterns to be isolated, helping in decision-making to reduce costs and increase productivity at any station, airport or port, as well as offering a better experience to the traveler ., increasing your satisfaction.
Regarding the specific needs of the hardware, in isolated or unattended stations, compact and robust video recording solutions are necessary , resistant to high temperatures even without ventilation, thus managing to reduce the failure rate and, therefore, maintenance costs. of the solution.
Public means of transport are perceived in many cities as unsafe environments, especially at night. Given this reality, it is highly recommended that the different media have wireless video surveillance measures, called on-board solutions, that help deter criminals as well as reassure passengers, promoting the use of said transport
Cameras used for mobile environments must be especially robust against changes in lighting, so that they can ensure maximum image quality both indoors and outdoors, especially on routes through tunnels, and in different weather conditions. A recommended technology for this need is WDR ( Wide Dynamic Range or Wide Dynamic Range), already incorporated in most IP cameras on the market. This technology is based on image adjustment algorithms that smooth the contrast between the brightest and darkest areas by measuring and dynamically adjusting the exposure of each pixel in the image.
As for the recording equipment, these also have special needs, since they must be robust against high temperatures, vibration and dust, as well as incorporate 4G modules for the transmission of images and real-time alerts to the control centers. There are even specific safety certifications for on-board electronic equipment, such as Safety of Flight (SOF), used in the aviation sector to demonstrate that the equipment does not represent any danger to the pilot, the aircraft or other equipment during flight conditions. normal and emergency operation of an aircraft.
Transport security control centers are critical points in the system due to their high demand for coordination and action on the thousands of mobile and fixed means to be controlled. These centers, both centralized and distributed, must be prepared for the monitoring of multiple security cameras to cover the entire transport flow, especially if an advanced video analytics solution is not available in the system.
For this, Videowalls can be used that allow security camera monitoring to be combined with other digital media such as web pages and images, to cover all the fronts to be controlled.
In addition, for installations with multiple operators working simultaneously, it is advisable to have a Streaming Server , which optimizes video display by multiple operators without duplicating streams, preserving low-speed link resources.
To cover all these aspects mentioned, the main national operators trust Lanaccess as a provider of their comprehensive video surveillance system, thanks to our robust, reliable and cyber-secure solutions, which optimize the use of communications bandwidth to manage and analyze remotely and intuitively thousands of cameras in distributed stations.
