The George Washington University Transportation Engineering Program and the AHB45 Subcommittee on Traffic Flow Modeling for Connected and Automated Vehicles (AHB45(3)) are inviting you to submit your abstract(s) to the 2017 Traffic and Granular Flow Conference (TGF17) that will be held in Washington DC, USA, between the 19th and the 22nd of July, 2017. The conference will be held immediately prior to the ISTTT 22 that will take place at the Northwestern University (Evanston, Illinois, USA) between the 24th and 26th of July, 2017. All accepted abstracts will be presented at the conference in plenary or poster sessions. Authors of the accepted abstracts will be invited to submit a full paper. All papers accepted for a poster or oral presentations will appear in the book of proceedings published by Springer. A selection of authors will be invited to publish an extended version of their papers in a special (journal) issue. The theme of the conference is: “From Molecular Interactions to Internet of Things and Smart Cities: The Role of Technology in the Understanding and the Evolution of Particle Dynamics”. The topics covered include but are not limited to: connected and automated vehicles (CAVs), granular flow and dynamics of granular materials, pedestrian detection and modeling, collective motion in biological systems, nano-particles and molecular dynamics, complex networks and Internet of Things (IoT). The deadline for abstract submission is January 30, 2017.
