By foot is another matter. Most cities and towns in the U.S. do not have sidewalk maps, and pedestrians are usually left to fend for themselves: Can you walk from your hotel to the restaurants on the other side of the highway? Is there a shortcut from downtown to the sports arena? And how do you get to that bus stop, anyway? https://techxplore.com/news/2023-03-open-source-tool-planners-pedestrian-networks.html Software Wed, 15 Mar 2023 09:35:03 EDT news598091700 Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new system to improve data collection at intersections. https://techxplore.com/news/2023-03-lidar-pedestrian-behavior-efficiency-safety.html Software Mon, 13 Mar 2023 10:14:10 EDT news597921246 The Swiss city of Lucerne voted Sunday to limit short-term rentals, including on the Airbnb platform, to a maximum of 90 days a year. https://techxplore.com/news/2023-03-swiss-city-lucerne-votes-restrict.html Business Mon, 13 Mar 2023 04:22:01 EDT news597900117 A ransomware attack against Oakland that has affected city services and exposed reams of sensitive personnel data is creating a nightmare for city officials who aren't sure what it will take to resolve the crisis. https://techxplore.com/news/2023-03-sight-oakland-ransomware-crisis.html Security Thu, 09 Mar 2023 13:10:02 EST news597588325 As smart cities continue to grow, one of the most significant challenges faced by drivers is finding parking space.
