This report consists of 17 papers that evaluate the accuracy of network-wide traffic states; network partitioning and incident detection using a macroscopic fundamental diagram; the influence of road layout on a network fundamental diagrams; areawide dynamics of pedestrian crowds; and pedestrian walking characteristics through angled corridors. This issue also explores group dynamics in pedestrian crowds; experimental investigation of pedestrian personal space; a mechanism of early-onset breakdown at on-ramp bottlenecks on Shanghai, China expressways; modeling and analysis of merging behavior at expressway on-ramp bottlenecks; and modeling of vehicle interactions during merges in congested weaving sections of freeway ramps. Additionally, this TRR summarizes volume delay functions based on stochastic capacity; the use of probe vehicle data to determine joint probability distributions of vehicle location and speed on an arterial road; real-time prediction of near-future traffic states on freeways; traffic flow predictions; a maximum pressure controller for stabilizing queues in signalized arterial networks; multiscale traffic flow modeling in mixed networks; and a linear programming model for estimating high-resolution freeway traffic states from vehicle identification and location data.
