Smart and Scalable Urban Signal Networks

Smart and Scalable Urban Signal Networks

The system is a real-time, adaptive traffic control system (or the Internet of Smart Intersections, in the sense of Smart IoT) that optimally schedules dynamic traffic flows in complex urban road networks, by integrating traffic theory with artificial intelligence (AI).

PopCity: Pittsburgh as a driving force behind transportation technology

… Pittsburgh boasts a comparable technology with Scalable Urban Traffic Control, or Surtrac, an artificial intelligence-based system… Like adaptive traffic signals, Surtrac, which was deployed at intersections in East Liberty earlier this year, responds in real-time as opposed to working on a fixed-time cycle. While the system operates similarly to PennDOT’s adaptive signals, Traffic 21 Executive Director Stan Caldwell explains that S

Presented work on Multimodal Traffic Control at IEEE ITS Conference, Qingdao, China

On October 10, Dr. Xie presented the work on multimodal urban traffic control at the 2014 IEEE International Conference on Intelligent Transportation Systems, Qingdao, China. This work extends our decentralized, schedule-driven approach to traffic network control in the direction of a broader mobility objective to optimize all modes of traffic that are central to sustainable urban living. We focus specifically on accommodating pedestrians and opt

Smart traffic signals listed as 25 Great Things About Computer Science at CMU

The smart and scalable urban traffic control system (invented by Xie, et al.) is listed in 25 Great Things  about Computer Science at Carnegie Mellon University. What’s so great about computer science at Carnegie Mellon? We’re glad you asked! Here are 25 great ideas from CMU computer scientists to think about as we celebrate the birthday of the School of Computer Science. 1.    Artificial intelligence, 1955-56 … 12. JAVA, 1991 … 25.

PopCity: New real-time traffic signal technology to hit the streets this June

PopCity: New real-time traffic signal technology to hit the streets this June

The city of Pittsburgh is soon extending its cutting-edge system of real-time traffic signals that adapt instantly to shifting traffic conditions. The new traffic signal technology is coming to the Baum-Centre corridor. This $1.8 million pilot project will provide the first-of-its-kind smart traffic technology from the city’s eastern edge almost to Downtown. … “Pittsburgh uses its quirks — in this case a tight urban street grid packed

Traffic Technology Today: Pittsburgh expands ‘smart’ traffic signal network

Traffic Technology Today: Pittsburgh expands ‘smart’ traffic signal network

The City of Pittsburgh and Carnegie Mellon University (CMU) are expanding a network of ‘smart’ traffic signals that monitor flow and instantly react, changing their timings to move vehicles through intersections more efficiently. The expansion of the project, which is due to be done by early next year, will add the signals to several intersections along Baum Boulevard and Centre Avenue, stretching from East Liberty to Oakland. When the installati

Canada.com: Advanced traffic signals can ease congestioned

… Projects stewarded by the U.S. Department of Transportation have shown that reducing traffic congestion has manifold benefits. The SURTRAC adaptive traffic control system implemented at some 20 Pittsburgh intersections has reduced travel time by 25 per cent and reduced GHG emissions by 21 per cent. Canada, which seeks to reduce its 2005 GHG levels by 20 per cent by 2020 – with vehicles accounting for 13 per cent of those levels &#82
