Proximity Information Resources for Special Events (SHRP 2 Reliability IDEA Research Report)

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. SHRP 2 Project R15B (Proximity Information Resources for Special Events) developed a mobile application, known as PRISM, to assist in management and communications during large events. The PRISM concept uses automated measurement capabilities to assess crowd metrics, bringing the concepts of transportation reliability to the pedestrian mode. PRISM was demonstrated at one event on the national mall, using a deployment of 11 portable sensors at strategic locations such as entrances, crossroads, and stages. Data from the sensors was delivered in real-time to a monitoring station and was post-processed for in-depth analysis. Additional data streams from social media (Twitter and Flickr) simulated data streams reflecting the availability of space in nearby parking garages, and the location of a roving medic were integrated into the real-time monitor display. The final report is available on the follow page.
