Characterizing and Quantifying the Shrinkage Resistance of Alkali-Activated (Cement Free) Concrete and Evaluating Potential Methods for Reducing Early-Age Cracking in Pavements and Bridges

This report summarizes the findings of an experimental investigation into shrinkage, and the mitigation thereof, in alkaliactivated fly ash and slag binders and concrete. The early-age (chemical and autogenous) and later-age (drying and carbonation) shrinkage of sodium silicate-activated fly ash and slag binders was evaluated in accordance with relevant specifications. The influence of activator concentration and water content on the resulting shrinkage was investigated. The shrinkage behavior of alkali-activated binders and concrete was compared to that of ordinary portland cement.

The Role of Social Media in Improving the Safety and Efficiency of Traffic Operations during Non-Routine Events such as Incidents and Planned Special Events

Social media has become an integral part of modern communication. There is however no clear consensus among transportation managers on how social media could or should be used to collect or disseminate actionable information. To provide guidance on the potential use of social media in transportation, a better understanding is needed of the message content as well as the path taken from the sender to the potential user of actionable information during crises and other non-routine events in the transportation system.

Integrated Incident Management System (IIMS) Web Client Application Development, Deployment and Evaluation: An Evaluation of a Potential IIMS Deployment in Western New York

Incident Management (IM) is an area of transportation management that can significantly decrease the congestion and increase the efficiency of transportation networks in non-ideal conditions. In this study, the existing state of the Integrated Incident Management System (IIMS) is reviewed, additional user requirements and applications are identified, potential obstacles to successful deployment are discussed, and identification of future steps towards deployment in western New York are determined.

Integrated Incident Management System (IIMS) Web Client Application Development, Deployment and Evaluation: Staten Island (SI) Demonstration Project

This evaluation report provides background on the development and findings. The aim of the UTRC project was to develop and deploy Portable IIMS based on Smartphone web applications. Previously, traditional IIMS was deployed in the field vehicles networked to central system. The transition from the vehicle-based IIMS to portable smartphones based applications has enhanced Stakeholders’ experiences and ability to increase usage, and now ready for large-scale deployment. The users and stakeholders-agencies have concluded this effort as a success.

Effect of Plug-in Hybrid Electric Vehicle Adoption on Gas Tax Revenue, Local Pollution, and Greenhouse Gas Emissions

Plug-in hybrid electric vehicles (PHEV) are likely to increase in popularity in the near future. However, the environmental benefits of PHEVs involve tradeoffs between the benefits of reduced tailpipe emissions against the drawbacks of increased emissions at marginal electric generation plants and reduced gasoline tax income. In this report, a model is developed that will enable these tradeoffs to be studied. The model accounts for local commuting patterns and marginal electric generation in New Jersey.

Evaluation of Public Private Partnership Contract Types for Roadway Construction, Maintenance and Rehabilitation

Public-private partnerships (PPPs) in transportation infrastructure projects refer to contractual agreements formed between a public Agency and a private sector entity to allow for greater private sector participation in project delivery. At the current time, most Agencies do not have a set of straightforward guidelines by which they decide whether to adopt PPP for a given project, and if to adopt one, which type of PPP should be adopted.

Port Resilience: Overcoming Threats to Maritime Infrastructure and Operations from Climate Change

In the coastal zone, seaports and their intermodal connectors are key types of infrastructure that support the global supply chain, provide regional economic activity, local transportation system services, and community jobs. The protection of coastal communities and their ports has been taken for granted during a prolonged period of climate stability. Recently there are growing concerns that a new period of climate change and severe weather events is emerging. Communities and their waterfront facilities are vulnerable to disruptions.

Environmental Impacts of Oil and Gas Brine Applications for Dust and Ice Control in New York

Transportation agencies are required to treat roads for dust and ice control to ensure adequate safety for travelers. This is commonly achieved through application of solid and liquid chemicals. These materials can be conventional rock salt, brine from rock salt, natural brine, or oil and gas brine. Due to the high cost of treating roads for the removal of snow and ice, in states with active oil and gas wells such as New York, the potential for using this brine to control dust or ice on roads is currently being explored.
