10/11/2023 0 Comments Reducing traffic gridlock![]() Traffic signal priority (TSP) gives extra green-light time to transit vehicles like buses and light rail, helping them stay on schedule and alleviating congestion at intersections. 3 – Traffic signal priority and emergency vehicle preemption The payoffs are less congestion, better safety, and fewer truck rolls. Then personnel at the traffic operations center can detect problems right away, remotely adjust signal phase and timing, and monitor for cybersecurity threats. Without network access, technicians have to drive to a site to make repairs or adjust signal phase and timing.Ĭontrollers can connect to the network via our industrial switches, industrial routers, or ultra-reliable wireless backhaul solutions. That means DOTs don’t find out about a signal malfunction until someone calls to report it. Many people are surprised to learn that most traffic signal controllers aren’t connected to a network. By using Ultra-Reliable Wireless Backhaul instead of cabling. Our routers stream real-time video to your operations center over cellular, Cisco Ultra-Reliable Wireless Backhaul, or fiber connections. Instead, mount cameras at the intersection and install a Cisco industrial router in a roadside cabinet. Video surveillance no longer requires expensive cabling throughout the city. And with real-time video analytics, cities can detect when someone walking with a cane or using a wheelchair or stroller needs more time to cross the street, and then automatically adjust the signal timing. ![]() When drivers know the roadway is monitored, they’re inclined to drive more safely, reducing traffic violations. Seeing when and where congestion occurs, you can alleviate it with actions like adjusting signal timing at particular times of day. Video surveillance helps to improve safety in several ways. 1 – Video surveillance at high-traffic intersections and highways In my next blog, I’ll talk more about the Cisco solutions behind them. Below are five projects for roadways and intersections that improve safety and reduce congestion. Investments with big payoffsĪgainst this backdrop, I’ve been hearing from state and local departments of transportation (DOTs) looking for the best investments to improve safety, increase efficiency, and reduce congestion and carbon footprints. an estimated $179 billion (source: Texas A&M Transportation Institute). We spend an average of 97 hours a year sitting in traffic-time I’d rather spend playing with my kids. Congestion is returning to pre-pandemic levels. ![]() Instead, the National Highway Traffic Safety Administration (NHTSA) estimates that traffic fatalities in 2020 were up 7.2% over 2019. Contrary to expectations, telework during the COVID-19 pandemic didn’t reduce accidents. The bill and its ramification positively impacts anyone who drives, bikes, or walks. Thanks to the new infrastructure bill, the pace of connecting roadside infrastructure is about to exponentially take off.
