This reduces the waiting time considerably in some cases.<\/p>\n<p>Now a team led by Horst Possegger from the Institute of Computer Graphics and Vision at Graz University of <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">Technology<\/a> (TU Graz) has developed the second generation of these smart traffic lights on behalf of Vienna&#8217;s Municipal Department 33 and in collaboration with G\u00fcnther Pichler GmbH and successfully tested them at four pedestrian crossings.<\/p>\n<p>The new system is now able to recognize people with mobility impairments or strollers thanks to improved camera resolution, higher computing power and an appropriately trained, deep learning-based model. It can also monitor and control several crossings simultaneously.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Up_to_300_teraflops_computing_power\"><\/span>Up to 300 teraflops computing power<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While the first-generation smart traffic lights in 2018 had a computing power of 0.5 teraflops, the new devices have values of between 100 and 300 teraflops (number of floating point operations per second). &#8220;This allows us to use a more complex and thus, more capable machine learning model, which means that people can be detected more accurately and robustly,&#8221; says project manager Possegger. Thanks to the increased camera resolution, the system can also recognize people with strollers or walking aids, such as rollators or crutches.<\/p>\n<p>&#8220;People with mobility impairments usually need longer to cross the road. Our traffic light system is able to recognize such needs very reliably so that the green phase can be extended as required,&#8221; explains Possegger.<\/p>\n<p>                                                                                                        <!-- TechX - News - In-article --><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Images_are_deleted_within_50_milliseconds\"><\/span>Images are deleted within 50 milliseconds<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The cameras evaluate an area of about 30 square meters in the waiting area of the traffic light, with the image data being exclusively processed locally and deleted within 50 milliseconds. Only the number of people and the categories of people, such as information on mobility restrictions, can be permanently documented if required. Traffic planners could use this purely statistical data to coordinate traffic light systems in a larger area or to provide the data basis for a demand-optimized redesign of the traffic light schedules.<\/p>\n<p>For data protection reasons, the new detector system was not developed using images of a real road situation, but with images from tests at Campus Inffeldgasse of TU Graz. The researchers filmed test subjects in various constellations and with different accessories.<\/p>\n<p>From the movement patterns, the system can correctly predict with an accuracy of 99% whether a person wants to cross the road. When it comes to recognizing mobility restrictions, the accuracy is 85% or more, depending on the mobility aid. In the system architecture, a special focus was placed on safety, so that even in the event of classification errors in a mobility aid, the green phase is requested\u2014in the worst case, with the previously usual &#8220;standard duration.&#8221;<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\tA Comprehensive Crossroad Camera Dataset of Mobility Aid Users. <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/papers.bmvc2023.org\/0743.pdf\" target=\"_blank\">papers.bmvc2023.org\/0743.pdf<\/a><\/p>\n<\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Graz University of Technology<br \/>\n                                                    \t\t\t\t\t\t\t\t\t\t\t\t\t<a rel=\"nofollow\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.tugraz.at\/\" target=\"_blank\" rel=\"nofollow\"><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                <strong>Citation<\/strong>:<br \/>\n                                                Vienna&#8217;s smart traffic lights are now getting even smarter (2024, December 1)<br \/>\n                                                retrieved 2 December 2024<br \/>\n                                                from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2024-11-vienna-smart-traffic-smarter.html\n                                            <\/p>\n<p>\n                                            This document is subject to copyright.
