Collective Behavior over Social Networks

Yan Leng, Collective Behavior over Social Networks Social networks are ubiquitous and shape individual behaviors; yet, behavioral data over networks are complex and stretch the limit of conventional analysis and models. In this talk, Dr. Leng presented two complementary projects that extend existing prediction and inference methods over social networks. First, she investigated how social…

Open Source Multi-Agent Virtual Simulation Test Bed in NYC

C2SMART researchers at NYU developed a virtual testbed for NYC using large-scale transportation simulation models built with the MATSim and SUMO open-source simulation platforms. In addition to the development of the integrated and open simulation platform, several algorithms and novel approaches for on-line calibration, real-time computation, etc. were developed using this new simulation tool. The…

Link Criticality Index for Analysis of Large Transportation Networks

Anil Yazici, Link Criticality Index (LCI) for Analysis of Large Transportation Networks Designing and maintaining resilient and robust transportation systems requires identification of links that are critical for the functionality of the network. Traditional traffic simulations techniques create a large computational burden, especially for larger traffic networks. This talk presented the recently developed Link Criticality…

Hani Nassif, Installation of a Smart Roadway Testbed in Brooklyn, NY to Measure the Impact of Overweight Trucks on Critical Infrastructure C2SMART Center researchers worked with the New York City Department of Transportation (NYCDOT) to establish and implement a new smart roadway testbed along a cantilevered section of the Brooklyn-Queens Expressway (Interstate 278) in Brooklyn,…

Xuegang (Jeff) Ban, Traffic Signal Optimization and Coordination in Connected Cities

Xuegang (Jeff) Ban, Traffic Signal Optimization and Coordination in Connected Cities Connected vehicles in smart cities, including vehicle to vehicle (V2V), vehicle to infrastructure (V2I), and vehicle to anything (V2X) communications, can provide more opportunities and impose more challenges for urban traffic signal control. This project webinar explored the basic research on developing signal control…

Hai Wang, Ride-sourcing Systems & Multi-objective Online Ride-Matching

Hai Wang, Ride-sourcing Systems & Multi-objective Online Ride-Matching This talk proposed a general framework to study the on-demand shared ride- sourcing transportation systems and summarized the relevant research problems in four areas, namely, demand, supply, platform operation, and system problems. The problem of online matching in the ride-sourcing systems was the main focus of this…
