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.
Alkali-activated concrete (AAC) is an emerging technology in the construction materials sector. Cement-free AAC is a promising environmentally-friendly alternative to ordinary portland cement (OPC) concrete. A comprehensive study was performed by researchers at Clarkson University to develop energy efficient and environmentally friendly cement-free concrete mixtures for pavement and bridge deck applications. Alkali-activated concrete (AAC) mixtures were developed using slag and fly ash as the sole binder and sodium silicate as the alkaline activating solution.

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.
This project develops a method for predicting coastal flooding considering climate change and sea level rise, and its impact on population and transportation network. In particular, a modeling framework has been proposed to predict flooding and estimate affected population and traffic systems needed for evacuation plans, and the following tasks have been conducted:
This projects main objective is to determine the most economical method to collect probe data and then to utilize this probe data to determine expanded and/or contracted lane closure hours for major construction projects. A cost benefit analysis will be included to measure the savings of using real-time traffic probe data versus existing traffic management approaches based on volume and capacity in the planning, design and implementation of lane closures, which are necessitated by major roadway construction.
