Greetings!
Travel time reliability--which is increasingly important to highways, arterials, transit, and air travel--is also important to pedestrians. When managing large crowds, performance measures relating to volume, density, and trajectory of pedestrians (crowd metrics) are essential. PRISM (PRoximity Information System for Mobility), which was developed in SHRP 2 Reliability IDEA Project L15B (Proximity Information Resources for Special Events), gives event organizers the ability to automatically measure crowd metrics. PRISM uses detectors that sense Bluetooth devices, such as cell phones, to identify the location of pedestrians. Software is then used to aggregate this data with data from Twitter and FlickR, and display the size, movement, directionality, and density of crowds in near real time. The potential uses for these crowd metrics include emergency management and deployment of event staff. This video showcases a demonstration of PRISM at the Sakura Matsuri 2012 Festival in Washington, D.C., which was conducted in cooperation with event organizer, the Japan-American Society.
