The Open Mode Integrated Transportation System (OMITS) forms a sustainable information infrastructure for communication within and between the mobile/Internet network, the roadway network, and the users’ social network. It manipulates the speed gap between different types of the network: information communication through cellular phones and the Internet is tremendously higher than that of vehicles on roadway, which is much faster than that of the social networking.

The University Transportation Research Center – Region 2 supported a study entitled “Connections Beyond Campus: An Evaluation of the Niagara Frontier Transportation Authority – University at Buffalo Transit Pass Program”. Unlimited Access transit passes have become common sustainability programming at many colleges and universities in cities both large and small across the United States.

The introduction of larger aircrafts on flexible airfield pavements has led to a need for asphalt mixtures capable of sustaining such heavy loads. This laboratory and analytical study investigated the mechanical responses of a number of modified asphalt mixtures to identify their potential for use in airfield aprons and taxiways that are subjected to heavy, static or slow-moving aircraft loads.

The I88 culvert crossing of Carrs Creek in Sidney, NY collapsed during the record setting Mid‐ Atlantic States Flood of June 2006. Rapid construction with geofoam as lightweight fill enabled partial reopening of I88 by Labor Day 2006. Shortly after reopening of the roadway, rapid settlements developed. The geofoam fill was removed and I88 was rebuilt using lightweight aggregates. An investigation of the rapid construction failure was completed in 2009. This report examines the failure of the re‐construction and the results of the subsequent investigation.

Transportation Infrastructure in the US is in need of maintenance and rehabilitation. Preservation of road networks at an acceptable level of serviceability subject to the stringent yearly maintenance and rehabilitation (M&R) budgets is a major challenge for State Departments of Transportation (DOTs). Decision-makers are required to develop an optimum financial plan to minimize the total cost of maintenance and rehabilitation for different expected improvement of the road network performance level during a given planning horizon.

The objective of this project was to develop a plan for deploying a statewide RWIS to support both current NYSDOT operations and future MDSS applications. To develop the plan, various information and data sources were investigated, including the current condition of NYSDOT’s RWIS network, potential RWIS station sites, data needed for supporting statewide MDSS applications, and NYS meteorological zones.

In this project, we derived a latent class model with a class assignment mechanism based on the latent bicycle status of the respondent. Two segments were identified: more-skilled and experienced cyclists, versus less-skilled- and non-cyclists. The two segments have different sensitivities to the factors that may encourage or discourage riding a bike. For instance, slope inclination is considered almost 3 times as bad by less-skilled cyclists.

A comprehensive study was performed to develop energy efficient and environmentally friendly alkali-activated cement-free concrete mixtures for pavement and bridge deck applications using sodium silicate-activated fly ash and slag as the sole binders. The effects of water content, air entrainment, alkali concentration, and curing temperature and duration on the resulting compressive strength and workability were evaluated. From these data, four mixtures were selected that showed potential for application in transportation infrastructure.

Emerging technologies offer transit agencies an opportunity to transform fundamental aspects of their operations and the way they communicate with their riders. With nearly ubiquitous smartphones and social media tools among growing ridership patterns, transit providers can use aggregate mobile phone data and social media posts to improve system management.
