The Falling Weight Deflectometer (FWD) is most commonly used to evaluate highway pavement structural condition for estimation of pavement remaining service life and overlay design. Recently, the need to accurately characterize layer material properties of the existing pavement has increased with the implementation of the new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG). Although a number of studies have been conducted for using FWD data in rehabilitation design, several challenges still exist due to the complex nature of pavement system.  MORE about Nondestructive Evaluation of Pavement Structural Condition for Rehabilitation Design

Bridge fires can present a severe hazard to the transportation infrastructure system. In fact, a nationwide survey by the New York State Department of Transportation (NYSDOT) has shown that fires have collapsed approximately three times as many bridges as earthquakes. Bridge fires are often intense as they may be fueled by gasoline from vehicles that have crashed in the vicinity of the bridge. Additionally, code recommendations and guidelines for fire protection of bridges are lax.  MORE about Analysis of Curved Weathering Steel Box Girder Bridges in Fire

Parking intrusion occurs when non-residents park on neighborhood streets in order to avoid parking fees while access nearby opportunities (e.g., retails, offices, or sports events). Such intrusion is environmentally undesirable because it invites driving to urban centers with convenient transit services and the worst traffic congestion. It encourages excessive search for parking on neighborhood streets that endangers local pedestrians, cyclists and children.  MORE about Measuring Parking Intrusion in New York City Neighborhoods using Parking Tickets and Vehicle Plate Registration Data

The NYU Poly research team proposes utilizing Bluetooth technology to estimate origin-destination demands and station wait times of users of the MTA New York City Subway system. If the entrance and exit turnstiles at subway stations are equipped with Bluetooth receivers, it is possible to capture O-D information for some percentage of the riders with visible Bluetooth devices. The riders who have electronic devices such as most cell phones, iPods, and computers carry unique information in their devices’ Bluetooth MAC address.  MORE about Real-time Estimation of Transit Origin-Destination Patterns and Delays Using Low-Cost Ubiquitous Advanced Technologies
